the upper part of the lateral lobes more or less infuscated aud gener- 

 ally with dusky markhigs on the disk, the lateral carinas on the meta- 

 zone generally black. Elytra light brown with ash}' markings, the 

 disk with a series of more or less distinct light diagonal spots; wings 

 deeply" fuliginous with translucent spaces between the cross yeins oyer 

 the greater part of thediscal area. Legs yellowish brown with obscure 

 darker mottlings on the femora, the posterior femora without scali- 

 form markings on the outer face, sometimes longitudinally marked 

 with a broken l)lackish line.

Type.— Cat. No. 1102, U. S. National Museum. 



Specimens examined. — The type, a male collected in northern Arizona 

 l)y Doctor Palmer, four males and four females from Arizona, Nevada, 

 and California, one male taken by Townsend, probably in New Mexico, 

 and a female from Lower California. Besides these, all of which are 

 in the U. S. National Museum collection, I haye seen specimens from 

 Arizona and California in the collections of Scudder, Bruner, and 

 Morse. 



This species was described by Thomas in the genus Locust <i from a 

 single male which was figured." Three years after the description of 

 the male, Thomas described the female from a specimen collected by 

 the Wheeler expedition. In 1897 Doctor Scudder erected the genus 

 Ckipnohotes for this species and its allies. Being the first species 

 described as well as the first to appear, both in table and discussion, 

 in Scudder's article establishing the genus Capnohotey., it is logically 

 the type of that genus. 



This species seems to occur as adults in Jul}' and August, and prol)abl3' 

 later. The series studied, including material from the Scudder and 

 Morse collections, exhibits considerable variation in the slenderness of 

 the elytra, length of the oyipositor, and amount of the posterior eleya- 

 tion of the pronotum. But the different phases of development in 

 these characters seem to extend throughout the range of the species 

 and probably do not indicate specific difl^erences. No specific differ- 

 ences were found to separate the Lower Californian specimen from 

 those of California or Arizona. 



Aside from Rile3"'s statement in the Standard Natural History that 

 they live in low and somber-colored vegetation, there is nothing
