BY T. D. A. COCKERELL, N. M. AGR. EXP. STA. 



Calliopsis meliloii, n. sp., $ . — Length, 5 mm.; head and thorax 

 wholly black, abdomen very dark brown, with yellowish-white markings. 

 Head, thorax, legs, and sides of abdomen with abundant long dull white 

 hair. Clypeus prominent, shining, with conspicuous sparse punctures, 

 its upper portion longitudinally sulcate in the middle, its whole surface 

 appearing bare, with only very short, inconspicuous hairs. On each side 

 of the clypeus is a shining bare eminence. Vertex closely punctured. 

 Mandibles brown. Antennae quite short, the hairy scape not much less 

 than half as long as the flagellum, the last joint of which is truncate and 

 somewhat flattened. 



Tegulae shining testaceous. Dorsum of metathorax bare, smooth. 

 Legs dark, knees and terminal joints of tarsi becoming paler. Wings 

 quite short, hyaline, iridescent, nervures and stigma light reddish-brown. 

 Second submarginal cell about three-fourths length of ist ; narrowed one- 

 half to marginal. Abdomen short and broad, with broad creamy-white 

 bands ; that on first segment narrowly interrupted in middle, and roundly 

 notched on each side behind ; that on second very broadly interrupted, 

 and also notched at sides ; those on third and fourth entire, notched at 

 sides behind ; finally an obscure broad subrufescent band partly on 

 fourth and partly on fifth segment. Anal fimbria dirty white. 



Habitat. — Las Cruces, N. M., on the College Farm, May ist, 1895 ; 

 swept from Melilotiis ijidica, together with Nomada, Sphecodes, Prosapis., 

 and four species of Ifalicius, viz.: bardus, stuitus, pectoraloides, and 

 meliloti. 



It is related to C. ductus, Cr., but differs in the abdominal bands 

 being white instead of yellow. The anal fimbria not fuscous, the wings 

 not at all dusky. It has some superficial resemblance to Perdita 

 albovittata. 



Calliopsis hirsutifrons, n. sp., ,^ . — Length about 6 mm.; pitch-black, 

 very shiny, thorax and abdomen without any pale markings, face-mark- 

 ings creamy-white. Face, including clypeus, scape, cheeks, occiput, 

 sides of thorax, post-scutellum, metathorax except basal middle, legs, and 

 lateral hind margins of abdominal segments, with rather dense and fairly 

 long white pubescence. Head transversely oval, ocelli small and close
