acter is that the face is entirely black, although there remains a white 

 spot at the base of the mandibles. The abdomen has a spot on each 

 side of the first two segments, a broadly interrupted band on the 

 third, and an almost continuous one on the fourth, these markings 

 being white. The fifth segment, as in australior, has neither band 

 nor spots ; the apical pubescence is entirely white. For the rest, the 

 characters are practically as in sdtulus. 



Hab.— Pasco, Wash., May 25, 1896 (T. Kincaid). 



Calliopsis clypeatus Cresson, 1878. 



Cresson had only a single $ . Prof. C. F. Baker has taken both 

 sexes in Colorado (No. 1,581, on Laramie River, Larimer Co., 

 8,500 ft., July 19, 1895). The 9 is like the $ , except that the face 

 is wholly dark : the antenna? shorter, with the flagellum, after the 

 third joint, dull ferruginous beneath ; the abdomen broader, the 

 apical portion with white pubescence, and the extreme apex with a 

 broad, dense, ochreous brush. 



Calliopsis boylei Ckll., 1896. 



This is not rare at Santa Fe, New Mexico. It is also found in 

 Colorado, a specimen before me was collected by Prof. C. F. Baker 

 (No. 1,600). The Colorado form has a yellow line on the scape, and 

 a study of it leads me to believe that C. boylei is probably only a 

 variety of C. ornatipes (Cress., 1872). In the typical boylei from 

 Sta. Fe, the scape is entirely black. 



Calliopsis coloradensis Cress., 1878. 



Santa Fe, N. M., on flowers of Grindelia squarrosa, Aug. 1 (Ckll. 

 4,029) ; and in Mr. Boyle's garden, Aug. 10 (Ckll. 4,397). The 

 face-marks are slightly tinged with pinkish, and the lateral marks 

 do not go up so far as would seem to have been the case in Cresson's 

 type ; yet the identity is evident. The specimens are females. 



Calliopsis andreniformis Smith, 1853, subsp. rh.odopb.ilus n. subsp. 



$ . The legs, instead of being entirely yellow, have the femora 

 with the basal two-thirds nearly all black, and all the tibia? with a 

 black patch behind ; sometimes the four hind tibiae have a dark 

 shade in front ; the scape is entirely black, or may have a narrow 

 yellow line in front; the yellow is paler throughout; the thoracic 

 pubescence is more scanty and grayish-white rather than ochraceous ; 

 otherwise there is little or no difference. 



9 . The face-marks are cream-color ; no rudiments of dog-ear 

 marks . wings clearer. This subspecies is more distinct in the <? 

 than 9 .
