This is a small red-abdomened species which superficially appears like A. pectidis (Cockerell). It differs from pectidis in several respects, such as the three submarginal cells, the coarser sculpturing, the well-developed subgenal coronet, and the bidentate labral process. It is here placed near A. accepta to which it is probably closely related in spite of lacking the high vertex and broad genal areas of accepta. A. aliciarum is one of those species which tic the accepta-group closely to the manifesta-group through species such as pectidis and verbesinae.

FEMALE. MEASUREMENTS AND RATIOS. N = 2; length, 9.0-10.0 mm; width, 3.0-3.5 mm; wing length, about 3.55 mm; FL/FW, 1.13; FOVL/FOVW, 2.40.

INTEGUMENTAL COLOR. Black except as follows: clypeus pale yellow except apical one-third or less with brown band with sinuous basal border and brown triangular maculae below tentorial pits; parocular area pale yellow to lower margin of facial fovea (upper margin of antennal fossa) and with narrow pale line between fovea and compound eye to within upper third of eye; supraclypeal area, scape and flagellar segments 410 below rufescent; tegulae rufescent; wing membranes infumate apically, hyaline basally, veins dark brown; terga hyaline apically, tergum 1 piceous in basal half or more, red apically near hyaline marginal area, terga 2-6 red basally or piceous basally except near hyaline apical area (holotype is dark), or basal area more or less infused with brown medially; sterna red but last two sterna becoming infused with brown; legs red except coxae, trochanters and femora reddish-brown.

STRUCTURE. Scape subequal to flagellar segments 1-3; flagellar segment 1 longer than 2 plus 3, segment 2 subequal to 3 and each shorter than segment 4. Eye about four times as long as broad, converging slightly to mandibles. Malar space linear, six times as broad as long. Mandible in repose extends beyond middle of labrum by less than one-fifth its length, bidentate, lacking ventrobasal lamella. Subgenal coronet present. Galea as in accepta. Maxillary palpus short, not quite reaching apex of galea, segments in ratio of about 1.3:1.5:1.0:0.9:0.8:1.3. Labial palpus as in accepta but ratio about 3.0:1.0:0.9:1.5. Labral process short, strongly bidentate. Clypeus somewhat flattened posteromedially, protruding beyond ends of eyes by about one-third its length, with coarse round punctures separated mostly by half a puncture width or less, slightly sparser along midline, surface moderately shiny, with irregular shagreening. Supraclypeal area with abundant small almost confluent punctures, surface moderately shiny. Genal area equal to or slightly broader than eye in profile, with small round punctures separated by one-half to one puncture width, surface shiny, unshagreened. Vertex above lateral ocellus equals slightly more than one ocellar diameter, above ocelli with crowded punctures, laterally with punctures separated mostly by one-halt to one puncture width or more, surface shiny. Facial fovea about half length of eye, rounded above, narrowly rounded below near eye margin, deeply impressed. Face above antennal fossae with almost confluent, moderate-sized punctures, without rugae except median ruga.

Pronotum normal, with minute punctures separated by one-half to one puncture width, becoming sparsely punctate laterally, surface shiny, unshagreened. Mesoscutum with small, round, regular, deep punctures separated by half a puncture width or less, surface shiny, shagreening delicate, if present. Scutellum and metanotum similar. Propodeum with enclosure with short, fine, longitudinal, median rugula, lateral to this finely areolate or granular or with incomplete or anastomizing, extremely fine, transverse rugulae; dorsolateral areas and posterior surface punctate, punctures sparser posteriorly, surfaces shiny, unshagreened; corbicular areas smooth, with widely-spaced punctures and surfaces slightly dulled by fine reticular shagreening. Fore wing with three submarginal cells; vein 1st m-cu meets second submarginal cell at about two-thirds distance from base of cell; pterostigma as in accepta. Middle basitarsus, tibial spurs and claws as in accepta.

Metasomal terga 1-4 basally with round, deep, regular punctures separated mostly by about one-half a puncture width, surfaces shiny, unshagreened, apical areas with punctures slightly smaller and more crowded. Terga 5 and 6 with punctures minute, well-separated, surfaces dulled by dense fine reticular shagreening. Pygidial plate somewhat V-shaped with well-rounded apex. Sterna 2-5 with narrow apical areas impunctate, basally with widely-scattered punctures except on sternum 5 punctures close-set near apical area, surfaces moderately dulled by reticular shagreening.

VESTITURE. White below and on sides to pale ochraceous above except as follows: dorsum of thorax may be dark ochraceous or pale brown in middle of sclerites (not in holotype); inner surfaces distitarsi and front and middle basitarsi yellow: inner surfaces hind basitarsi yellow infused with reddish-brown in some specimens (not holotype). Thoracic dorsum with hairs extremely short, erect, highly plumose, scale-like under low magnifications but branches not as dense as in manifesta or pectidis, terga 2-4 with apical pubescent fasciae, often interrupted medially on tergum 2 (interrupted in holotype); terga 1-4 with basal areas with abundant, short, erect, largely simple hairs scarcely obscuring surfaces; sterna without subapical fimbriae except on sternum 5 where poorly developed. Propodeal corbicula incomplete anteriorly, with long simple or sparsely barbed internal hairs. Trochanteral flocculus complete, weak. Tibial scopal hairs plumose, of normal length, white.

MALE. MEASUREMENTS AND RATIOS. N = 2; length, about 9 mm; width, about 2.5 mm; wing length, 2.90-3.08 mm; FL/FW, about 1.18; FS1/FS2, 2.09-2.18.

INTEGUMENTAL COLOR. As in female except as follows: parocular area with upper margin rounded, reaching level of upper margins antennal fossae, without pale line extending up alongside of compound eye; terga 1-6 piceous basally except rufescent in extremely narrow area just basad of hyaline apical margins; hind tibiae and tarsi dark red.

STRUCTURE. Antennae short, barely reaching middle of tegulae in repose; scape equal or slightly longer than flagellar segments 1-3; flagellar segment 1 longer than segments 2 plus 3, segment 2 shorter than 3 which is shorter than 4. Eye slightly less than three times as long as broad, converging towards mandibles. Malar space, mandible, galea, genal area, vertex and face as in female. Maxillary palpal ratio about 0.9:1.0:0.8:0.7:0.6:1.0. Labial palpal ratio about 2.7:1.0:0.9:0.8. Labral process bidentate, narrow, reflexed. Clypeus and supraclypeal area as in female.

Sculpturing of thorax and metasoma as in female except as follows: pronotal punctures separated mostly by one puncture width or slightly more; propodeum as in female in one specimen but transverse rugulae lacking in second, finely shagreened, propodeal lateral surface with punctures slightly smaller than mesepisternal and sparser ventrad, surface shiny; terga 1-4 with apical areas deeply impressed with reflexed rims. Sternum 6 relatively flat with a broad, V-shaped, apical emargination.

Genital capsule and sterna 7 and 8 as figured (Figs. 40-44); note extremely short and blunt gonoforceps and apices of penis valves, sternum 7 with V-shaped apical emargination and sparse hairs, sternum 8 with apex entire.

VESTITURE. As in female but thoracic dorsum with hairs slightly longer and slightly less plumose (not forming a mat-like covering); tergal basal area hairs longer; sterna 3-5 with subapical fimbriae of long, slightly curled, white hairs.

TYPE MATERIAL. The holotype female (USNM No. 13,394) of aliciarum from Organ Pass, New Mexico, September 29, 1896, was collected by X1X. D. A. Cockerell.
