A NEW ALPINE GRASSHOPPER FROM WESTERN CANADA. 



BY E. M. WALKER, TORONTO. 



Among a large number of Orthoptera taken by myself during a trip 

 to the Pacific Coast by the Canadian Pacific Railway there is one 

 species belonging to the Melanopli which I was unable to determine 

 from Scudder's " Revision " of the group, and could not *even satisfy 

 myself as to its generic place. I therefore sent a pair to Mr. Scudder, who 

 informed me that it was a new species of Aseuioplus, but that a change 

 would be necessary in the description of that genus as given in his 

 "Revision of the Melanopli" in order to receive my species. I had 

 noticed the resemblance to Asemoplus in the extremity of the male 

 abdomen, but the total absence of tegmina and other points of dis- 

 similarity caused my uncertainty regarding its true generic position. 



I have accordingly prepared the following description taken from 

 3 (J 's and 5 9 '5, of which 2 (^ 's and i ? were taken near Sandon, B. C, 

 in the Gold Range, and the others on Mt. Piron, near Laggan, Alberta. 

 Asetnophis niidus^ n. sp. 



Rather stout and strongly built ; tegmina and wings entirely absent ; 

 dull olivaceous above in the ? , black with two longitudinal dorsal yellow 

 stripes in the $ . 



Frontal costa not prominent, fading before the clypeus, equal, 

 sulcate at and below the ocellus, or sometimes throughout in the male, a 

 little wider than the first antennal joint in the ^ , about half as wide 

 again in the 9 • Vertex a little tumid, scarcely raised above the 

 pronotum ; fastigium rather steeply declivent, very slightly arcuate, 

 about on a level with the eyes or sometimes a little below in the (^ , 

 feebly depressed, considerably expanded anteriorly. 



Interspace between the eyes half as broad again in the ^ , twice 

 as broad in the 9 as the first antennal joint. Eyes rather small, a little 

 prominent in the (^ , but little longer than broad, subtruncate anteriorly, 

 about as long as the infra-ocular portion of the gena;. Antenna; shorter 

 than the hind femora, in the 9 about as long as the head and pronotum,
