Extracted from: Melissodes rivalis Cresson (1872 & 1873) Trans. Am. Ent. Soc. 4. p. 292

Male.—Black, head and thorax clothed with a dense whitish pubescence, that on occiput and thorax above slightly tinged with pale ochraceous; clypeus yellowish-white; tips of mandibles honey-yellow; antennae as long as head and thorax, brown or pale fulvous beneath, sometimes entirely fulvous; posterior disk of mesothorax and scutellum very thinly clothed with pubescence which is short and generally slightly mixed with black; tegulae fuscous; wings hyaline, apical margin faintly dusky; legs clothed with short pale pubescence, dense on tibiae and tarsi and yellowish on latter; abdomen oblong ovate, convex, shining, minutely punctured, thinly clothed with a short pale pubescence, first segment at base and sides clothed with a rather long, suberect pale pubescence, each segment with a subapical fascia of short appressed whitish pubescence, generally more or less interrupted medially on basal segments, quite narrow on first segment, moderately broad on remaining segments, lateral margin of fourth and following segments carinate, ending in a prominent tooth on fifth and following segments, that on the sixth large and subacute. Length .45-.55 inch.

Five specimens. (Belfrage; Boll) Nearly allied to the male of menuachus, but with shorter antennae and more distinctly banded abdomen.

Extracted from: Melissodes mysops Cockerell (1905) Entomologist 38, p. 146

Appears as Melissodes mysops in this excerpt.

Male. Length nearly 14 mm., pubescence dull white, some black on scutellum, and black on the basal parts of the abdominal segments except the first; clypeus lemon-yellow, its upper-margin black; labrum black; mandibles without a yellow spot; flagellum red beneath. Very close to M. cnici, Rob., from wich it differs this; yellow of clypeus only obscurely trilobed; face broader; eyes (when dry) pale bluish-grey; antennae darker; ventral hair of thorax not black; scutellum with black hair in middle; hair of legs not black; disc of mesothorax and scutellum more shining, the punctures more separated; abdomen narrower and longer, with weak light hair-bands, failing in the middle; lateral subapical teeth longer and narrower.

Female. Length about 14 mm.; face broad, facial quadrangle much broader than long; eyes light grey; flagellum stained with red beneath; hind part of mesothorax, and scutellum, shining, with well-separated punctures, and sparsely cloted with erect black hairl pubescence of legs black, but scopa on outer side on hind tibiae and base of tarsi long, under side of abdomen and lower part of pleura black, that at apex of abdomen dark fuscous or black. Differs from M. cinici, Rob., by the conspicuous black hair on disc of thorax, the more shining and less closely and coarsely punctured scutellum, and the narrower abdomen, with distinct pale hair-bands, especially on the third and fourth segments.

Extracted from: Melissodes mysops Cockerell (1907) Entomologist

Appears as Melissodes mysops in this excerpt.

Mr. S. A. Rohwer took one female and fourteen males at flowers of Cardaus acaulescens at Florissant, July 24th-29th, 1907. The males mostly differ from the type in having the yellow of the clypeus strongly trilobed, and the scutellum is often without black hair; but the species remains quite distinct from M. cnici.
