three pale longitudinal bands, evanescent 

 posteriorly before reaching the scutellum. 

 Halteres yellow, club large, somewhat 

 longer than its pedicel. Abdomen shovel 

 shaped, deep chrome jellow, thinly pube- 

 scent above with whitish hairs, which give 

 it a sericeous appearance in certain lights. 



Legs pale 3'ello\v, tibiae slightly dusky, 

 tarsi blackish at their distal ends, other- 

 wise brownish. 



Wings clear, iridescent, veins dark brown, 

 the first longitudinal paler. 



Hab. On yellow flowers of Compositae, 

 grounds of Agricultural College, Las Cruces, 

 N. M., Sept. 1S94 {Miss. J. Casad). 



A $ was taken at San Augustine, N. M., 

 on flowers, Aug. 29, 1S94 {CkH., 2260). It 

 resembles the $ , but the abdomen is nar- 

 ro%ver and the eyes are contiguous. 



This species is interesting from its colour, 

 which is exactly that of the flowers it fre- 

 quents. It occurs on the same flowers as 

 the similarly colored bee, Perdita luleola 

 Ckll. ined. Prof. C. H. T. Townsend tells 

 me that he remembers finding a similar 

 species in Michigan, but it was not 

 determined.

I know of the lai\"a tVom Nevada (Prof. 

 J. J. Rivers), Montana (Mr. C. A. Wiley), 

 Colorado (Mr. H. W. Nash) and Wyoming. 

 I feel satisfied from a comparison of bred 

 and captured specimens from these and 

 other localities that there is only this one 

 species from the Rocky Mountains to the 

 Sierras and from Canada (Mr. F. H. WoUey 

 Dod) to Mexico. C. fragilis is the western 

 representative of a}nericana. and is in turn 

 represented in the Pacific Northwest by 

 fluvialis. C. disstria extends throughout 

 the ranges of americana and plrivialis and 

 also extends into California {erosa and 

 tlioracica are synonyms) ; but does not 

 enter the range oi fragilis to my knowledge.* 

 The other species {califoriiica, eonstricta 

 and ambisimilis) appear to be confined to 

 California, and are yet imperfectly worked 

 out. The following life history is based 

 on larvae bred from eggs kindly sent me 

 by iMr. H. W. Nash of Pueblo, Col. 



Eggs. Colutnnar, flat above, rounded

* Since the above was written, I have seen disstria 

 from Guadalajara, Mexico.
