| Links | Identification Note: Males often have bright yellow markings on either side of the labrum ....the process is dark as is the center of the labrum. Some specimens are all dark, or only small marks. However, as far as we know, this is the only species of Andrena with some form of yellow marking on its labrum.

This common eastern species is quite distinctive and probably should constitute a group by itself. It is related to the accepta group by the yellow clypeus of the female, but the parocular areas of both sexes lack yellow maculae. It seems to be closely related to A. asteris Robertson and A. simplex Smith, but differs from either of these by the sculpturing, the form of the flagellar segments, the yellow female clypeus, and the sculpturing of the propodeum as described below.
FEMALE. MEASUREMENTS AND RATIOS. � N = 20; length, 12.5-14.0 mm; width, 3.5-4.5 mm; wing length, M = 4.51 � 0.216 mm; FL/FW, M = 0.99 � 0.056; FOVL/FOVW, M = 2.55 � 0.036.
INTEGUMENTAL COLOR. � Black except as follows: clypeus yellow except narrow brown apical margin and small dark spots below and mesad of tentorial pits; flagellar segments 4-10 rufescent below; tegulae piceous; wing membranes moderately infumate; sterna narrowly hyaline apically; distitarsi rufescent; tibial spurs yellow or yellowish-brown.
STRUCTURE. � Scape subequal in length to flagellar segments 1-3; flagellar segment 1 equal to or slightly shorter than segments 2 through 4, segment 2 slightly shorter than 3, and 3 distinctly shorter than 4. Eye about three and three-fourths times as long as broad, inner margins slightly converging towards vertex. Malar space linear, about six times as broad as long. Mandible (outer) in repose extends beyond middle of labrum by one-fourth or less of its own length, with distinct ventrobasal lamella. Subgenal coronet well developed; hypostomal carina without process. Galea densely tessellate, opaque, la lend surface indistinct, surface curves gently from dorsum to side, lateral area equals about half dorsal surface. Maxillary palpus not reaching tip of galea, segments in ratio of about 1.3:1.5:1.0:1.1:0.9:1.1. Labial palpus with first segment curved on inner margin, flattened, broader at apex than at base, segments in ratio of about 2.5:1.5:1.0:1.3. Labral process short, about five times as broad as long, evenly curved apically with shallow, indistinct emargination. Clypeus evenly rounded, protruding below lower ends of eyes by about one-fourth its length, impunctate along narrow midline, elsewhere with irregularly-sized punctures separated by one-half to one or more puncture widths, surface shiny, unshagreened medially, with fine reticular shagreening peripherally. Supraclypeal area with small round punctures separated by one to two puncture widths, surface moderately dulled by longitudinal shagreening. Genal area slightly broader than eye in profile, with minute punctures, near eye margin separated by one to two puncture widths, posteriorly mostly by two to four puncture widths, surface dulled by reticular shagreening. Vertex short, above Literal ocellus equals about one and one-half ocellar diameters, with minute sparse punctures and dense tessellation dulling surface. Face above antennal fossae with coarse, anastomizing, longitudinal rugae, interrugal spaces with small indistinct punctures and reticular shagreening dulling surface. Facial fovea extends just below middle of eye, rounded and broad above, narrow but rounded below and turned slightly from eye margin, shallow.
Pronotum normal, with minute, indistinct, relatively sparse punctures, surface opaque, finely tessellate. Mesoscutum with shallow round punctures of moderate size separated mostly by one to two puncture widths, surface opaque (slightly shiny mediobasally), tessellate. Scutellum and metanotum similar to mesoscutum. Propodeal enclosure opaque, coarsely tessellate, narrow basal zone with short, irregular rugae sometimes forming shallow, incomplete areola; dorsolateral and posterior areas sculptured like mesoscutum but punctures more crowded; corbicular area with sparse punctures in upper half, surface moderately shiny, with coarse, reticular shagreening. Mesepisternal sculpturing like mesoscutal. Metepisternum below impunctate and reticularly shagreened like corbicular area. Fore wing with three submarginal cells; vein 1st m-cu meets second submarginal cell beyond middle of cell and usually at about two-thirds distance from base of cell; pterostigma narrow, equal in width or slightly broader than from inner margin of prestigma to wing margin. Middle basitarsus slightly broader than hind basitarsus, with evenly curved sides, broadest near middle. Tibial spurs and claws normal.
Metasomal terga 1-4 with basal segments with punctures indistinct due to dense tessellation dulling surfaces, apical areas with punctures more crowded and distinct, tessellation grading into reticular shagreening apically. Terga 5 and 6 with punctures small, distinct, separated by two to tour puncture widths, surfaces dulled by reticular shagreening. Pygidial plate V-shaped with truncate apex (occasionally worn and then rounded). Sterna with narrow apical impunctate margin, basal half impunctate or extremely sparsely punctate, apical half except margin with abundant punctures separated by two to three puncture widths, surfaces dulled by coarse reticular shagreening.
VESTITURE. � Head white, sparse except labrum and mandibles with long golden or golden-brown hairs. Thoracic vestiture white, dorsum with hairs sparse, of moderate length, tending to be ochraceous posteromedially on mesoscutum and medially on scutellum. Terga 2�4 with basal areas with extremely short, simple suberect, extremely sparse, black hairs; tergum 1 almost glabrous except at sides. Terga 2-4 with white apical pubescent fasciae but these interrupted medially (broadly so on tergum 2). Terga 5 and 6 with long hairs golden-ochraceous to brownish. Sternal hairs white to pale ochraceous, concentrated near apices of sterna. Propodeal corbicula incomplete anteriorly, with long, minutely barbed, internal hairs in upper half. Trochanteral flocculus complete, moderately thick. Tibial scopa ochraceous or yellowish, plumose with median hairs long, plumose in outer third or slightly more. Legs white to ochraceous except inner surfaces tarsi golden-yellow.
MALE. MEASUREMENTS AND RATIOS. � N = 20; length, 10.0-13.0 mm; width, 2.5-3.5 mm; wing length, M = 3.94 � 0.171 mm; FL/FW, M = 1.00 � 0.056; FS1/FS2, M = 2.32 � 0.034.
INTEGUMENTAL COLOR. � Color essentially identical with female.
STRUCTURE. � Antennae barely surpass tegulae in repose; scape distinctly shorter than flagellar segments 1-3; flagellar segment 1 subequal in length to segments 2 plus 3, segment 2 shorter than 3 and 3 subequal to 4. Eye about four times as long as broad, inner margins parallel or slightly converging towards vertex. Malar space, galeae, hypostomal carina, and mandibles as in female but without ventrobasal lamella. Maxillary palpus as in female but ratio about 1.0:1.2:1.0:0.8:0.7:0.9. Labial palpus as in female but ratio about 2.7:1.5:1.0:1.6. Labral process as in female. Clypeus protrudes beyond lower margin of eyes by about one-fourth its length evenly rounded, with small scattered punctures separated mostly by one to three puncture widths, often impunctate along midline, surface shiny, unshagreened except at extreme lateral angles. Supraclypeal area with abundant small punctures separated by half a puncture width or slightly more, surface moderately shiny, finely shagreened. Genal area, vertex, and face above antennal fossae as in female. Small, vestigial facial fovea or pseudofoveae present near margin of upper end of eyes. Thoracic sculpturing as in female except propodeal enclosure often with basal half with small areola and corbicular area with sparse punctures scattered throughout and surface opaque, tessellate. Wings as in female but second submarginal cell frequently smaller, especially above, and vein 1st m-cu often near middle of cell. Tergal and sternal sculpturing as in female except as follows: tergum 5 like 2-4; terga 6 and 7 like 5 and 6 of female; sterna with punctures sparse in apical half except impunctate margin. Sternum 6 with strong, apical, V-shaped emargination. Genital capsule and sterna 7 and 8 (Figs. 65-09) similar to those of accepta but differ as follows: gonoforceps rather abruptly narrowed near tips; penis valves extremely narrowed apically, narrower near base; dorsal lobes of gonocoxites very short; sternum 7 with apicolateral lobes bluntly rounded, long, emargination narrow; Sternum 8 with neck region slightly expanded medially, shallowly emarginate.
VESTITURE. � Color as in female except terga with minute basal area hairs pale; distribution as in female except usual secondary sexual differences.
TYPE MATERIAL. � The holotype female (INHS) was collected at Carlinville, Illinois, September 20, 1890, on Bidens chrysanthemoides, by Charles A. Robertson (Robertson No. 9529). A male in the same collection bears the label "lectoallotype" and the Robertson No. 15,265. Since Robertson described aliciae from a single female specimen this cannot be an allotype of any kind. Also, this male was collected at Carlinville in 1893, two years after the original description was published.
DISTRIBUTION. � This species is known to occur from Minnesota south to Kansas and east to New York and Georgia (Fig. 5). It has been taken from July 30 through October 2, but chiefly from the end of August through September. In addition to the type the author has examined 164 females and 72 males from localities listed below (published records are also listed): GEORGIA: Tifton. ILLINOIS: Beverly Hills; Carlinville; Chicago; Palos; Southern Illinois. IOWA: Mt. Pleasant (6 miles S.W.). KANSAS: Doniphan County; Douglas County. MARYLAND: Cabin John; Chesapeake Beach; Glen Echo; Plummer's Island. MICHIGAN: Pontiac. MINNESOTA: Cass County; Hastings; Lake Independence, Hennepin Co.; Powder Plant Woods, Ramsey Co.; St. Paul; Zumbra Heights, Carver Co. NEBRASKA: Lincoln; Omaha; West Point. NEW JERSEY: Bear Swamp (near Ramsey); Englewood; Greenwood Lakes; Ramsey. NEW YORK: Tuxedo Park. NORTH CAROLINA: Bryson City; Marion; Swannanoa. OHIO: Mansfield; Stark County. PENNSYLVANIA: Cambridge; Alleghany Co.; Dorseyville; Ohio Pyle; Philadelphia. SOUTH CAROLINA: Greenville. VIRGINIA: Bellview; Chain Bridge; Great Falls; Hunter; Offute's Island. WISCONSIN: Farmington, Polk Co.; Fountain City, Buffalo Co.; Milwaukee; Maiden Rock; Pierce Co.; Never's Dam, Polk Co.; Washington Co. Canada. ONTARIO: Toronto.
FLORAL RECORDS. � Of the specimens examined by the author only 53 representing 23 collections had floral data. Of these, 28 specimens (8 collections) were from some species of Helianthus and all but one of the remainder were taken on some species of Compositae. The exception was one male taken from the flower of a squash (Cucurbita sp.). In view of these data one can state that A. aliciae is an oligolege of the Compositae and seems to prefer the genus Helianthus. This agrees reasonably well with Robertson's conclusions (Robertson, 1925, 1926). Plants from which aliciae has been collected are listed below (this list includes published records).
Aster azurella, Bidens aristosa, B. chrysanthemoides, B. laevis, B. trichosperma, Cucurbita sp., Helianthus sp., H. angustifotius, H. divaricatus, H. giganteus, H. microcephalus, H. sirumosns, H. tuberosus, Heliopsis helianthoides, Rudbeckia sp., R. fulgida, R. laciniata, R. lanceolata, R. triloba, Silphium perfoliatum, Solidago sp., S. occidentale.

Identification | |
Extracted from Joel Gardner. "The mining bees of Minnesota (unpublished manuscript)" Andrena aliciae is the only Minnesota Andrena in which the clypeus is yellow in the
female.
Extracted from: Charles, R. (1895). Notes on bees, with Descriptions of New Species. Transactions of the American Entomological Society Vol. 22, No. 2. pp. 115-128.
This was described from a single female specimen. I now have
nine females agreeing with the type. The male agrees with the
female, except in characters peculiar to the sex. This is the only
Andrena known to me in which the female has the clypeus yellow,
the same as in the male.
