apex densely covered with brownish-black hair, but there is a tuft 

 of light hair on each side beneath. 



Habitat: Claremont, California {Baker; Pomona coll. 148). 

 This looks like AnthophoruJa bnincri Crawf., but is at once separ- 

 ated by the roughened disc of first abdominal segment, the black 

 hair at end of abdomen, and the minute dark stigma; there is evi- 

 dently no real affinity.- 



Mclissndes pygmaa Cresson, from the description, is apparently 

 an Anthophoriila or Exomalopsis ; indeed the description might well 

 apply to J. bruneri. 



E. vchithnts and E. mchuuirus are not typical Exomalopsis. The 

 genus as at present understood contains some rather diverse ele- 

 ments. 



Bombomclccta niaculata (Viereck) 

 Viereck described this as a variety of B. separata, but it seems 

 to be a distinct species. A female from Claremont {Baker; Po- 

 mona coll. 162), has the spots on third and fourth segments quite 

 large and quadrate, and there are small spots on the fifth. 



Coelioxxs megatricha sp. n. 

 $ Length about 11 mm.; black, with bright ferruginous legs 

 (the femora dusky beneath) and rather dark red tegul^e; no red on 

 abdomen, above or below; mandibles dark red subapically; face 

 and front densely covered with long white hair; antennae black, third 

 joint distinctly longer than fourth; vertex with very large punctures, 

 which latcrad of the ocelli are distinctly separated, leaving inter- 

 spaces equal to the size of punctures; eyes pea-green, with very long 

 hair; mesothorax and scutellum densely and very strongly punctured, 

 middle of mesothorax with little longitudinal ridges; scutellum 

 rounded behind, teeth at sides long, finger-like, slightly incurved; 

 pleura and metathorax covered with long shaggy white hair; anterior 

 coxcC with strong spines; anterior trochanters and femora with much 

 white hair beneath ; spurs red ; wings clear, the apical margin broadly 

 dusky; abdomen with white hair-bands at apices of segments; dor- 

 sum and sides of first segment closely punctured; second and third 

 segments with very deep transverse impressions, and strongly punc- 

 tured, the ridge just behind the impression with sparse punctures;
