DISTRIBUTION�British Columbia to Mexico, east to Wisconsin and Illinois. July to October.

FLOWER RECORDS�According to LaBerge (1961) Grindelia and Solidago are preferred by menuachus as a pollen source, but it has been collected also on species of Argemone, Aster, Cassia, Chrysopsis, Chrysothamnus, Cleome, Eustoma, Gaillardia, Gutierrezia, Helianthus, Hymenothrix, Medicago, Melilotus, Petalostemum, Polygonum, Rudbeckia, Sidalcea, Verbena, Viguiera and Xanthocephalum.

Appears as Melissodes pallida in this excerpt.

♀- Black, clothed with pale pubescence, which inclines to ochraceous on the thorax above ; face rather closely pubescent, clypeus closely and strongly punctured, mandibles rufous in middle, with a yellow streak at apex, antennas black, third joint about equaling next two together, flagellum dull testaceous beneath. Thorax above densely pubescent, except on disc of mesonotum and scutellum, more sparsely punctured on former. Wings subhyaline, second submarginal cell a little smaller than first, third narrowing one-half above, nervures dull testaceous, tegulas piceous. Legs black, apical joints of tarsi ferruginous ; pubescence pale ochraceous, becoming fuscous on apex of tibiae and tarsi, scopa pale, oh the basal joint of hind tarsi within it is black. Abdomen opaque, basal segment with pale pubescence at base and laterally, base of second and broad apical margins of segments 2-4 with appressed white pubescence, segments 5 and 6 with black pubescence, the abdomen beneath has the pubescence fuscous, paler towards apex. Length 14 mm.

Appears as Melissodes octobris in this excerpt.

Female. Length about 10.5 mm., anterior wing 8.2; black, with pale, faintly tawny hair. sooty or black at end of abdomen. and black on inner side hind tarsi, but white on inner side of hind tibiae; flagellum red beneath except basally the ends of the joints dusky; tegulae very dark brown. with light hair; wings hyaline. suffused with reddish, eyes pure black. but drying to pale grey. This is a species with a very broad short head and very wide face. like M. pallidicincta; Ckll., of which I should consider it a variety. but for the fact that the first tergite (except the depressed apical portion) is very distinctly though finely punctured. as seen under a lens and is moderately shining. whereas in M. pallidicincta (and also its var. erythrina Ckll.) this part is dull and not distinctly punctured. The clypeus is dull and very densely punctured all over. not shining in middle as in pallidicincta. The punctures are dense and more regular than in erythrina. but it agrees with that form in having a distinct though delicate median raised line. Sides of face rather dull, very hairy; supraclypeal area smooth and shining: each side of vertex with a broad shining basin ; no dark hairs on head or thorax above; disc of mesothorax posteriorly polished and sparsely but strongly punctured; scutellum shining, but more punctured than in erythrina; posterior truncation of metathorax dull, but with a pair of shining foveae at lower end (in erythrina represented by narrow shining bands, and about the same in pallidicincta); venation as in pallidicincta; scopa of hind legs very large. full of the bright orange Grindelia pollen (the type of erythrina has collected red pollen), abdomen broad. hind margins of tergites brownish; declivity of first tergite with white hair: bands at base and middle second tergite, and middle of third and fourth; depression of second tergite broader (antero-posteriorly) than the raised part above. The rather broad whitish margin of first tergite of pallidicincta (and erythrina) is replaced by a mere line. The abdominal bands appear to be feebly developed. but they would doubtless appear stronger in a freshly emerged specimen, though surely not as in pallidicincta. The hair of sides and under parts of thorax is all light. In Robertson’s (1905) table this runs out at 16. It is easily distinguished from the superficially similar M. confusiformis incondita Ckll. by the reddish wings, highly polished disc of mesothorax and distinctly punctured first tergite. From M. glenwoodensis Ckll. it is known by the shape of head. light hair on inner side of hind tibiae, and other characters. In my table of 1906 (Trans. Am. Ent. Soc.) it runs to group K. and under this to 6. Type. From Hudson. COLORADO, October 1. 193.3, In the author's collection.
