Bombus proximusy Cresson, 1863. 



This has priority of place over Howardi, Cresson, and 

 must be used for the species. The proximus form is the 

 usual one in New Mexico (Monument Rock&c), but Miss W. 

 Porter took a male of B. proximus, var. Howardi {B. Howardi, 

 Cress. 1863), at San Ignacio, Sept. 1, 1899. The var. 

 Howardi has the second and third segments of the abdomen 

 yellow (some black hair at the base of the second), whereas 

 proximus proper has the second segment black as well as the 

 first. 



Bombusjuxtus, Cresson, 1878. 



This has a very perfect mimic in Volucella facialis. Will., 

 which Miss Wilmatte Porter collected in company with it on 

 flowers of wild plum at Beulah, N. M., May 30, 1899.
