TRIMEROTROPIS CRISTATA, new species. 



Closely related to Trlmerotrojyl-s te.rana^ from which it may be dis- 

 tinguished b}^ the following characters: 



Color as in that species, but with a reddish tinge sometimes replac- 

 ing fuscous gray. Scutellum of the vertex deep, with a distinct median 

 carina; eyes decidedly shorter than the genal grooves. Pronotum with 

 the median carina very strongly cristate on the prozone, and equally 

 distinctly bilobate, the first lobe being one-half and the second fully 

 as high as long; on the metazone a slight l)ut distinct raised line. Lat- 

 eral carinse present only on the front of the metazone; the latter little 

 more than once and a half as long as the prozone, with the process 

 strongly obtuse-angular, the margins straight, and the tip rounded. 

 Tegmina with the light area prevailing in the anterior and posterior 

 fields and about equaling the dark in the middle field. Wings as in 

 that species, but transparent and faintly tinged with yellowish green 

 on the disk, Avith the fuscous band narrower and scarcely at all con- 

 tinued on the posterior border toward the base. Posterior femora as 

 in that species, but with the black deeper and more extensive on the 

 inner face and lower sulcus, and less distinct on the outer face. Pos- 

 terior tibite obscure yellow, with . no subbasal annulus. Length of 

 body, female, 26-29 mm.; length of tegmina, 27-28 mm.; length of 

 posterior femora, 13i mm. 



One female, San Julio, Lower California, Charles D. Haines, col- 

 lector, April; one female, 4,300 feet. Salt Lake Valley, Utah, August 

 1 to 4, Bruner collection. 



This species has been mistaken for Conozoa .wldfrons^ but it is xerj 

 unlike that species as I recognize it, and certainly does not answer to 

 Saussure's description.
