fei-ruginous ; tegulie yellowish-white ; wings long, strongly dusky at 

 tip, b. n. meeting t. m. a little on the outer side, second s. m. nearly 

 as large as third ; abdomen strongly punctured, with five entire yellow 

 bands ; apical plate very strongly notched ; venter with the first two 

 segments largely ferruginous, the third and fourth with broad dull 

 yellow bands. In my table of Rocky Mountain Nomada (Bull. 94, 

 Colo. Exp. Sta.) this runs to A\ snoivi, Cresson, to which it appears 

 to be allied. It differs, however, by the ferruginous colour on the 

 metathorax, the absence of black marks on the legs, and the band 

 on first abdominal segment not " deeply indented on each side 

 anteriorly." The scape is obscurely whitish beneath, not with a 

 white spot. It is possible that it represents a southern race or sub- 

 species of y. snoici. The spine on anterior coxa is ferruginous, of 

 moderate length.
