Diagnosis. Although separated from E. bifasciatus in the key, this species most closely resembles E. ilicis among Canadian Epeolus, particularly in the campanulate shape of the pseudopygidial area of T5 in the female. Epeolus ¡uds and E. lectoides exhibit several structural similarities (F2 of female antenna noticeably longer than wide, axilla distinctly hooked, and metasomal terga with sparse punctation), but in contrast to E. lucís the mandible of E. lectoides is with a preapical tooth, the ventrolateral half of the mesopleuron of E. lectoides ‘s sparsely punctate, and the axilla of E. Iectoides is angled posteriorly and its tip extends well beyond the midlength of the mesoscutellum.

Distribution in Canada: Central Canada (Map 9).

FEMALE—Length 8-10 mm.; black, scape and basal segment of flagellum more testaceous, antennae otherwise brownish-piceous; mandibles and tubercles more or less reddened, tegulae and legs testaceous, axillae sometimes reddened; lateral ocelli separated from margin of vertex by about their own diameter; cheeks very narrow, subcarinate posteriorly; labrum considerably broader than median length, the subapical tubercles quite distinct; mandibles simple, inner margin not angulate; scutellum quite deeply impressed medially on posterior margin (fig. 110), axillae robust, acute, tips strongly divergent from sides of scutellum, subcarinate laterally; wings with the usual three submarginal cells, hyaline basally, becoming rather deeply infuscated apically, veins brownish; pubescence very short, either very thin or appressed, front of face densely silvery tomentose, and venter of thorax covered with dense, silvery tomentum, the scale-like hairs becoming sparse on pleura above; pronotum quite densely covered with pale yellowish tomentum, scutum with a pair of anterior, longitudinal patches of yellowish tomentum on each side of midline; abdominal terga 1-4 with transverse, subapical, pale yellowish fasciae that are narrowly interrupted medially, that on tergum 1 rather broad but quite narrow, somewhat separated from margin of plate on 2-4, 5 with a broad patch of dense, greyish tomentum on each side; punctures quite deep and distinct in general, rather sparse between ocelli and eyes and below ocelli, becoming fine and close on lower portion of face and on cheeks; punctures deep and distinct, quite sparse or well separated on pleura below, becoming rather close above, rather close along mid-line of scutum but becoming quite sparse on each side, scutum quite deeply impressed medially on posterior margin, punctures coarse and sub- contiguous, those on axillae coarse and irregular; tegulae very finely and rather closely punctate; punctures of the more basal abdominal terga rather fine but quite deep and distinct, slightly separated in general, but variable, usually bearing very short, dark, plumose setae, apical margins of the terga slightly and rather broadly depressed, becoming yellowish-hyaline along rims, punctures fading out apically, those on tergum 5 minute and very close; pseudopygidium quite extensive, median length much more than half its apical width.

MALE—Agrees in most respects with description of female, but pygidium broadly rounded, median length about equal to basal width, surface rather smooth and only very obscurely punctate.

DISTRIBUTION—Illinois to the New England states, south to Georgia; June to September.

FLOWER RECORDS—Ceanothus, Cephalanthus, Helenium, Hypericum and Rhus. Recorded by Robertson (1929) on Pycnanthemum.


Identification
E. lectoides is a very distinctive bee. In both sexes the axillae are strongly hooked, with the pointed end of that hook being long, quite acute, and reaching nearly to the rear edge of the scutellum. Also, the pattern of pits on the thorax is very distinct. On the scutum, scutellum, and mesopleura the surface is extremely smooth and shiny and the pits are large and sparse. The interpit spaces are irregular with many spaces being as large or larger than the pits. In the East, this pattern of pits and overall appearance of the surfaces of the thorax is specific to this species.
