dots, and triangular lateral face-marks, white, the latter in shape not very 

 far from a half-circle, but the ends more produced and the inner (orbital) 

 margin a little concave. Mandibles mostly white without. Fiagellum 

 black above, coffee-brown beneath. 



Disc of mesothorax with conspicuous, very sparse punctures ; at 

 sides of mesothorax, and on scutellum, they are much closer. TegulcS 

 dark chestnut-brown. Legs black, anterior tibise in front, and first joint 

 of all the tarsi, cream colour ; remaining joints of tarsi subrufescent. 

 Claws deeply cleft. Wings hyaline, with a faint smoky tinge, which does 

 not extend to the external margin ; nervures and stigma dark brown, 

 marginal cell long, the tip roundly truncate, minutely appendiculate. 

 Second submarginal a little shorter than ist, narrowed a little less than 

 one-half to marginal. Abdomen narrow, strongly but rather sparsely 

 punctured, the segments transversely grooved adjacent to the sutures. 

 Hind lateral margins of segments with white hair bands. 



Habitat. — Albuquerque, N. M , middle of August, 1895 [Ckll., 4527]. 

 Something like C. pauper, but hairy, and the tibiae are differently 

 marked. It resembles a good deal the $ of C. albitarsis, which I took 

 on Rudbeckia laciniata, at Santa Fe, N. M., July 19th. In a/bit arsis, 

 however, the face is not nearly so hairy, the face-marks are pale yellow, 

 and the lateral marks are obtuse instead of pointed above. 



Calliopsis fraterculus, n. sp., $. — Length about 6^ mm., pitch- 

 black, with the ciypeus, triangular marks at sides of face, and tibiae in part, 

 pale lemon-yellow, tarsi light. Head broader than long, shining, the 

 ocelli in pits, a conspicuous prominence adjacent to the summit of each 

 eye, occiput and cheeks with large, more or less confluent, punctures. 

 Vertex with very few punctures, front with large subconfluent punctures ; 

 ciypeus punctured, high, light yellow, with its piceous apical margin 

 produced into a tooth on each side ; lateral face-marks triangular, rounded 

 above, not extending as high as antennal sockets ; labrum truncate, 

 mandibles wholly dark ; antennie short, reaching about to tegulte, flagellum 

 dark brown. Thorax wholly dark, with large punctures ; pubescence of 

 head and thorax sparse and inconspicuous, white, specially noticeable only 

 on each side of antennae, on border of prothorax, beneath the wings, and 

 at the sides of the metathorax. Punctures of scutellum and post-scutellum 

 very large and like those of mesothorax, those of metathorax smaller and 

 closer. Base of metathorax with obscure longitudinal wrinkles, but no 

 well-defined smooth space behind them. Tegulse shining dark reddish-
