This species seems most closely related to the following species 

 (capnopfera) , with which it shares a tendency toward ferruginous 

 markings. There is no tooth on the posterior coxa, the female lacks 

 a pygidial area and lateral ridges on the sixth tergite, and the male 

 lacks the tooth on the posterior proximal edge of the intermediate 

 femur. The legs are wholly ferruginous. 



SPECIMENS EXAMINED 



New Mexico. 



Texas: Clarendon (August 11, 1905, C. R. Jones) ; Jacksonville (June 28, 1906, 



F. C. Bishopp) ; Mineola (June 26, 1906, F. C. Bishopp) ; Rosser (August 



23, 1905, C. R. Jones). 



Handlirsch reports the species also from Kentucky. 



BICYRTES TRISTIS C. L. Fox 



Bicyrtes trisHs C. L. Fox, Proc. Cal. Acad. Sci., vol. 12, 1923, p. 435. 



This species was described from a single male taken at La Paz^ 

 Lower California. It is closely related to oapnopfera and viesU- 

 lensis, from which species it may be distinguished by the lack of 

 maculation on the metanotum, the narrower fasciae on the tergites, 

 and by the form of the seventh tergite, which in this species is much 

 narrowed at the apex. 



BICYRTES CAPNOPTERA (Handlirsch)

The wings of this species are infumated, very heavily in the case 

 of some specimens, much less so in the case of others. The female 

 bears a well-marked pygidial area on the sixth tergite set off by 

 distinct lateral ridges, the apical part of the area being somewhat 

 rugose. The male shows no structural modifications of legs or 

 antennae that may serve to distinguish it from the males of other 

 species,
