seventh of the male are invaribly black. Uufortunately, all speci- 

 mens are not typical, and it is these nontypical forms that cause the 

 difficulty in identification. The white forms of parata might be 

 considered a distinct species were it not for the fact that there is an 

 intermediate series passing by gradations over to the yellow form 

 of farata on the one side and another series passing likewise over to 

 ventralis on the other side. Much more work must be done in the 

 field before the problem here presented can be solved in a satisfactory 

 manner. 



SPECIMENS EXAMINED 



California: Los Angeles County (September, Coquillet) ; San Bernardino 



County (May, Coquillet), 

 Netw Mexico: Pecos (September 2, Cockerell).

The species has also been reported from Utah and Arizona. 



BICYRTES ODONTOPHORA (Handlirsch) 



Figure 36 



Bemhidula odontopliora Handlirsch, Sitz. Akad. Wisseusch, Wien, Math.-Nat, 

 CI., vol. 98, 1889, p. 482.— Dalla Torre, Cat. Hym., vol. 8, 1897, p. 495. 



The male of this species can not be confused with that of any other 

 species known to me. The dilated and flattened segments of the 

 anterior tarsus give to the males of this species a character unique 

 in the genus. Handlirsch separates the females of this species from 

 those of discisa, which most closely resemble it, chiefly on the charac- 

 ter of the punctation of the scutellum, which is much finer than on 

 discisa. This character, unless both species are available for com- 

 parison, is difficult to use. I have before me a single female that I 

 have referred to this species. The discal maculations on the scutum 

 are lines and the lateral spots on the scutellum are approximately 

 rectangular, whereas the corresponding maculations on discisa are 

 really spots on the scutum and triangular spots on the scutellum. 

 The female of inendica is distinguished from both discisa and odon- 

 tophora by having the tibiae and the tarsi entirely yellow. 



SPECIMENS EXAMINED 



Bolivia: Near mouth of Rio Maxiri (September, W. M. Mann). 



Peru: Puerto Bermudez (Cornell University Expedition). 



Venezuela: Rio Moto, Cuara District (October, 1909, M. A. Carricker). 



The female referred to this species bears the label, " Furo de 

 K-esaco, 10 Sept., night. Cornell Univ. Exped." The specimens on 

 which Handlirsch based his description of the species were from 

 Peru.
