Hab. Denver, Colo., 1889 (S. A. Johnson). 



This species runs in Fox's table (Proc. Acad. Nat. Sci. 

 Phil., 1895, p. 354) to B. connexus Fox, but it is not that spe- 

 cies. It probably is more closely related to B. spinolae or B. 

 amoena, but may be separated from these species by the fore- 

 going table.

Steniolia duplicata Prov. 



Two females, Cortez, Col., Aug. 10, 1903 ; female, Boulder, 

 Col., Sept. 7, 1907 (Roh.). We have also seen this species 

 from L,as Cruces, New Mexico, Aug. 3Oth, at fls. of Solidago 

 canadcnsis (Townsend). This species has so far only been 

 found on the plains. It is probably a southern form, finding 

 its northern limit in Colorado. 



Steniolia obliqua Cress. 



Male and female at Florissant, Col., June and July, some at 

 fls. of Edivinia americana (Roh.) ; Ward, Col., July, 1905, at 

 fls. of Gilia (Ckll.) ; Wet Mountain Valley, Custer Co., Col. 

 (Ckll. ). This is the most common Bembicid in the mountains. 

 So far it is not been reported from the plains.
