and dark in color, the pattern being strongly marked and the tibiae 

 purplish in color. 



In the locations where this species was captured it was found plenti- 

 ful among desert plants, excepting at Cima where individuals were 

 scarce and were found in thick thorny bushes. 



The previously published records of the species are from Fort Whip- 

 ple and Yuma, Arizona, and the Mohave Desert. 



iEoloplus oculatus Scudder. 



This interesting species, previously known only from Mohave, 

 Arizona, is represented in the series before us by six specimens, two 

 males and four females, taken at Cottonwood, September 9. The 

 prominent character of the eyes, mentioned by Scudder in his original 

 description of the species which was based on a unique male, is by no 

 means as pronounced in the female as in the male sex, although when 

 compared with females of M. arizonensis the same sex of this species 

 can be separated with little difficulty. The species is quite as variable 

 in size as most of the others of the genus, but the specimens before us 

 are quite constant in coloration. 



These insects were fairly plentiful in a low white desert bush, which 

 they would not leave and were in consequence difficult to capture. 



Melanoplus herbaceus Brunei-. 



At Indio, July 29, this species swarmed in an irrigated alfalfa field 

 and in high weeds, a series of twelve males and nine females being- 

 taken. A pair of this species was also taken on vegetation on irri- 

 gated land at Las Vegas, Nevada, August 10. This is one of the most 

 active species of the genus Melanoplus. 



The Indio males are nearly equally divided between the typical 

 form and that called flavescens by Scudder, while several specimens 

 are perfectly intermediate in character. All of the specimens are 

 in the green phase with more or less distinct postocular bars or no 

 traces of the same, except one in the brown phase and several approach- 

 ing the same. 



The species has previously been recorded from California at San 

 Diego and Indio, this constituting, however, the first Nevada record. 

 Melanoplus devastator Scudder. 



The collections made in California in 1907 contain an extensive 

 series of this very variable species, representing the following localities : 

 Mill Valley, August 23, nine males, nine females; Santa Cruz Moun- 

 tains, August 28, one male, one female; Merced, August 30, thirteen 

 males, ten females; Raymond, September 3, five males, thirteen
