10 THE CANADIAN ENTOMOLOGIST. 



ACRIDID/E. 



Stenobothi-tis cequalis Scudd. Quite a large series of what appears to 

 be this insect were taken July i6, at Yakima River. The specimens differ 

 from eastern ones in several respects, but not enough to warrant describing 

 them as new. The occiput is a trifle longer than usual, and the middle row 

 of spots on the tegmina extends almost to the tip. There are males and 

 females of both greenish and brownish-gray colors. 



Stenobothrus coloradus Thos. A few examples of the ordinary form 

 on Yakima River, July i6. 



Stenobothrus curtipmnis Scudd. This trim little species is represented 

 by quite a large number of specimens, among which at least three well 

 marked varieties occur. They were taken at various points along the 

 Yakima River in July. 



Stenobothrus sp. ? A single specimen of a species resembling S. 

 brtmneus. and perhaps that species, but so badly damaged that it is 

 difficult to place it with a certainty. Same locality as the preceding. 



Chloealtis abdonmialis ? Thos. The collection contains a single male 

 which is doubtfully referred to this species. Locality not noted. 



Aulocara elliottii Thos. This species was numerous at Yakima and 



Ellensburg, as well as at many other points in eastern W. T. Among the 



specimens examined I find two well marked varieties which agree with 



Mr. Scudder's description of A. cccrtileipes sufficiently close to be referred 



, to that species, which is a synonym of Stauronotus elliottii Thos. 



Dissosteira Carolina Linn. Three specimens of this wide-spread 

 species were taken at Portland, Oregon. 



Circotettix undulatus Thos. A few at Yakima, July i6. 



Circotettix carlingia?ius Thos. Same locality as the preceding. 



Trimerotropis suffusa Scudd^ A few specimens from some point 'n\ 

 Washington Ter. which I neglected to note when they were examined. 



Trimerotropis vinculata Scudd. W. T. 



Trimerotropis pseudofasciata Scudd. A single male from some point 

 in eastern W. T. This species was found by me on Birch Cr. in central 

 Idaho, where it was quite common during July and August, 1883. 



Trimerotropis coeruleipennis, n. sp. 



Distinct from all other North American species with which I am 

 acquainted in the coloring of the wings. 



Wings without the median dusky band, faint co2rulean blue at the
