66 E. T. CRESSON. 



thickly clothed with a long pale pubescence; abdomen oblong-ovate, shining, 

 strongly punctured, the depressed apical margin being smooth and impunc- 

 tured and obscure testaceous, base of third segment and the remaining seg- 

 ments thickly clothed with a short appressed ochraceous sericeous pubescence; 

 anal fimbria ochraceous. Length .35 inch. 



'J,. — ^More coarsely punctured than Q and more pubescent; abdomen more 

 sparsely and coarsely punctured, the segments depressed at base and having on 

 each side a patch of pale sericeous pile, not very distinct, but seen only when 

 viewed in certain lights. Length .30 inch. 



Ifah. — Mexico, (Sumichrast). Three specimens. Distinguished 

 from all the other species by the very coarse sculpturing of the head 

 and thorax. Resembles sefhiops Cress., in form, but much smaller 

 and more coarsely sculptured. 



Calliopsis illinoiensis. — %. — Black, shining, head and thorax quite 

 thickly clothed with a short whitish pubescence, tinged on vertex and meso- 

 thorax with ochraceous; sides oj" face not higher up than clypeus, the clypeus 

 entirely, labrum, middle of mandibles, and dot on tubercles lemon-yellow; 

 flagellum and tegulfe pale testaceous; wings dusky, slightly darker at apex; 

 second submarginal cell narrowed one-half to the marginal, receiving the first 

 recurrent nervure at about one-fourth from the base and the second about 

 one-fifth from the apex; legs clothed with pale glittering pubescence; knees, 

 anterior tibise in front, base of posterior pair and all the tarsi pale yellow; 

 abdomen elongate-ovate, shining, thinly pubescent except at tip where the 

 pubescence is rather dense, apical margin of the segments depressed and 

 obscure testaceous. Length .20 inch. 



Hub. — Illinois. Six specimens. This was presumed, both by Mr. 

 Smith and myself, to be the S of andreni/unnis, bu;: judging from 

 analogy in coloradensis, a closely allied species, the % of andreni- 

 formis must have a broad form like the 9 ^ ^"^^ li^G that of fiavtpes 

 Sm., which is doubtless the true % of that species. 



Calliopsis pauper. — 9 • — Uniformly shining piceous black, finely punc- 

 tured, very slightly pubescent ; clypeus with larger scattered punctures; tips 

 of mandibles, flagellum beneath and tegulse testaceous; mesothorax very finely 

 and densely punctured; metathorax faintly striolate at base; wings hyaline 

 iridescent, slightly dusky at apex, marginal cell obliquely truncate at tip, 

 second submarginal narrowed towards marginal, receiving the first recurrent 

 nervure one-fourth from its base, and the second very near or at the tip; legs 

 clothed with short pale glittering pubescence, anterior pair and all the tarsi 

 brown; abdomen oblong ovate, subconvex, shining, clothed with pale pubes- 

 cence at apex. Length .22 inch. 



% . — More pubescent than 9> lower corner of face, clypeus, spot on labrum, 

 and the mandibles white; all the knees, anterior tibiae, base and apex of two 

 posterior pairs, and all the tarsi yellowish-white. Length .20 inch. 



Hah. — New York ; Colorado. Six specimens. This little species 

 has the body almost destitute of pubescence, otherwise it closely 

 resembles iUmoiensis.
