the disc; base of metathorax roughened but glistening; legs densely 

 hairy, the hair pale ochreous-tinted ; hind tibiae and basitarsi with a 

 very broad loose scopa, hair on inner side of hind basitarsi pale 

 ferruginous; teguls piceous ; wings rather short, faintly grayish, 

 with a milky appearance in certain lights; greater part of abdomen 

 densely covered with felt-like very pale ochreous pubescence, but 

 apex with pale ferruginous; base of second segment with the hair 

 so thin as to leave a dark band; first segment bare in middle, finely 

 punctured; hind margin of first segment (tegument) broadly red- 

 dened, and the second and third the same, only in these the color 

 is hidden by the pubescence; venter with bands of red-golden hair 

 alternating with pale. 



Habitat: Claremont, California {Baker; Pomona coll. 153). 

 Very like Alelissodes stearusi Ckll., which is to be called Exo7na- 

 lopsis stearusi, but readily distinguished by the shorter and rela- 

 tively broader marginal cell, the well though finely punctured disc 

 of first abdominal segment, and the much shorter third antennal 

 joint (length 480 microns in stearusi, 350 microns in velutiuus) . 

 The apical plate of abdomen is much broader than in stearusi, with 

 straight sides. Both species look like some Xenoglossodes, from 

 which the most conspicuous superficial distinction is the bare pol- 

 ished disc of mesothorax. A second specimen of E. velutiuus bears 

 the number 147.

 scutellum with sculpture and arrangement of hair as in E. veluti- 

 uus; legs with long pale hair, the copious scopa of hind legs wholly 

 pale; a black brush at end of hind basitarsi; tegulae piceous, wings

 of the segments exposed and appearing black; fifth segment and
