fortably settled in the shadows cast by weeds, etc., but never so comforta- 

 bly but that it follows the shadow as the latter shifts. 



59. Roopedor mibilum Say. Barber Co. (Cragin). 



This very variable insect is found throughout the entire country, from 

 the British line southward to Texas, and from the eastern portion of Ne- 

 braska and Kansas, westward t> the Rocky Mountains. It seldom occurs 

 in numbers, and as a rule, is rather rare than otherwise. During the past 

 summer, however, while I was passing through the valley of the Lower 

 Yellowstone in Montana, I was surprised to find it by the hundreds upon 

 the borich lands a few miles back from the River. It was represented in all 

 shades, from deep, shining black, to pale yellowish brown, and also varied 

 greatly in size. It appeared to be feeding upon sunflowers and several 

 other weeds that had been left almost untouched by the various other spe- 

 cies of locusts chat were swarming throughout the immediate neighbor- 

 hood. 



60. Aulocara Elliottii Thos. Garden City, (Cragin). 



This species was first described by Prof. Cyrus Thomas as Stauronotus 

 Elliotti, arid afterwards by Scudder as Aulocara coeruleipes. It does not 

 belong to the genus Stauronotus, and therefore must be placed in the new 

 one created for the reception of it and a closely allied species. 



61. Aulocara? sp. Barber Co. (Cragin). 



The survey collection contains specimens of a locust which I have never 

 been able to place satisfactorily to myself, but which is so common through- 

 out the central portion of the United States that there can be no doubt of 

 its having been described. In its general appearance it comes close to the 

 genus Aulocara as limited by Scudder, but also differs from that genus in 

 several important characters. It also appraches the genera Stenobothrus 

 and Gomphocerus, and appears to connect the two groups. I will send 

 specimens of it to Prof. Scudder for determination, and will report the re- 

 sult in a future paper. 



62. Phlibostroma ? quadrimaculata Thos. Garden City (Cragin). 



I place this insect in the above named genus with some hesitation, be- 

 cause I have only glanced at the types of P. picta, the insect upon which 

 the genus was founded, and that at a time when I had no specimens of my 

 own with me to label. The members of this genus also resemble the Steno- 

 bothri in their general appearance, and, if I am correct in my present de- 

 termination, several species that belong here have been placed in the genus 

 Stenobothrus by both Thomas and Uhler. 



6$. Acridimn frontaiis Thos. Garden City and Barber Co. (Cragin) ; 

 Shawnee Co. ( H. J. Adams and R. E. McCampbell). 



This is the Pezotettix xpeciosa of Scudder (U. S. Geol. Surv. Neb., 

 1872, p. 250). 



64. Acridium rubigiiiosum Harr. Labette Co. (Newlon). 



This and the following species generally occur in regions where oak 

 abounds, and in such localities can be found very early in spring as larvae 

 and pup^e. Especially is this true of the present species. In the vicinity 

 of Washington. I). C., I have taken it throughout the entire winter in 

 company with Chimarocephla viridifasciata and Hippiscus discoideus.
