Length 12 mm.

♂- Resembles the female, the pubescence being longer and thinner, tegulae and nervures sometimes darker, segments 2-4 of abdomen with margins sometimes more evidently testaceous, fascia at base of second segment white, fifth segment also with a white fascia, and sixth with pubescence sometimes black, sometimes pale ; clypeus, labrum and mandibles at base pale yellow, the latter at apex with an orange-yellow streak ; third joint of antennae as long, or twice as long, as second, fourth longest of all, flagellum fulvous beneath, apex of tibiae and the tarsi ferruginous, or sometimes the knees and the tibies and tarsi entirely ferruginous. Length 11-12 mm.

Extracted from: Melissodes suffusa Cockerell (1934) Am. Mus. Novitates 697, p. 10

Appears as Melissodes suffusa in this excerpt.

Female. – A peculiar variety, with the margin of first tergite broadly hyaline, and the following tergites with the tegument red under the broad bands, the red part of second and third tergites in middle being much broader than the black base; mesothorax with rich fulvous hair, and almost no dark, but much dark brown hair on scutellum; vertex with bright fulvous hair, but face and cheeks with white; labrum dusky red, with a tuft of red hair at apex; flagellum red beneath. The general appearance of the abdomen is that it is black as far as middle of second tergite, and pale red beyond, with the bases of tergites blackish.

Female. – Black; head clothed with short dense cinereous pubescence, that on occiput fulvous; clypeus finely punctured; mandibles with a pale spot near base; flagellum dull testaceous beneath; thorax clothed with a short dense ochraceous pubescence, more or less tinged with fulvous above, that on disk of mesothorax and scutellum black; tegulae dull testaceous; wings sub hyaline, tinged with yellowish, nervures pale fuscous, second submarginal cell nearly as long as first, the third broadly rounded at tip and narrowed one-half towards marginal; legs clothed with ochraceous or pale fulvous pubescence, long and dense on posterior tibiae and tarsi, tips of tarsi ferruginous; base and sides of first segment of abdomen and sides of apical segments clothed with ochraceous pubescence, broad apical margin of segments 2-4 and base of second narrowly, densely clothed with a short appressed cinereous pile; apical margin of first segment narrowly testaceous; ventral segments fringed with yellow or ochraceous pubescence. Length .50 inch.
