166 THE CANADIAN ENTOMOLOGIST. 



Coelioxys grmdellœ denve7'ensis, n. sul)?;i). — Four males ; Denver, 

 Colorado, Aug. 6 to 25, 1908 (Mrs, C. Bennett). Eyes light red (green 

 in C. grindèliœ Ckll,) ; fourth ventral segment strongly emarginate (entire 

 in grindeliœ). Otherwise they seem about the same. Face densely 

 covered with white hair; antennae entirely black: bevelled space on 

 cheeks rugose but shining ; anterior coxae with large flattened spines ; 

 tegulae black, the margin sometimes dark reddish ; legs black, including 

 tarsi ; spurs dark ; second abdominal segment on each side subLiterally 

 with a more or less evident but small shining raised area ; teeth on each 

 side of scutellum long ; teeth at sides of. sixth abdominal segment long ; 

 lower apical teeth of abdomen not broad. In Robertson's table this runs 

 out at 3, although the first abdominal segment is very hairy at sides, and 

 sublaterally has distinct indications of a basal band. The anterior part of 

 the mesothorax is conspicuously but diffusedly hairy, instead of having 

 well-defined spots as in C deplanata. 



Coelioxys angelica Cockerell. — The male, previously unknown, has 

 been taken by Mr. F. Grinnell, jr., in Strawberry Valley, San Jacinto 

 Mts., California, alt. 6,000 ft., July 18. By 'its small size and general 

 appearance, it closely resembles C. deani Ckll., but the sulcus on the last 

 abdominal segment is much broader. It agrees with the female angelica 

 in having a series of large pits along the basal margin of the mesothorax. 

 The anterior coxœ have short spine-. 



Coelioxys texana vegana, n. subsp. — Beulah, New Mexico, 8,000 ft., 

 August, (Cockerell). I had erroneously placed this with C. moesta. It 

 differs from C texana as shown in the table ; by the black legs, with red 

 only at the apices of the joints, it resembles C. alter?iaia Say. It differs 

 from Say's description o{ alt em at a by the dark chestnut-red tegulse, and the 

 total absence of any white hair band bordering the mesothorax, though 

 there is a little tuft of hair just before the axillaj. The abdomen is 

 sparsely punctured, as in texana; the fourth ventral segment has slender 

 apical spines. 



Coelioxys erysimi, n. sp. — Male at flowers oî Erysimum parvifioru?n ; 

 Rifle, Colorado, July 3 to 8 (S. A. Rohwer). 



Length about 10 mm.; black, with white hair, abundant on head and 

 thorax ; tegulcC black ; legs entirely black ; hind spurs red ; eyes pale 

 green, with long hair; antennae and mandibles black; cheeks hairy all 

 over ; vertex, mesothorax and scutellum with large, quite dense, punctures ; 

 scutellum rounded behind ; axillar spines moderately long, obtuse ; wings
