58 THE CANADIAN ENTOMOLOGIST, 



occurring in the U. S. Nat. Museum. It first came to my notice in the 

 State on August 8, 1897, when it was found near DeLong, Fulton County, 

 in an open peat bog which was surrounded on all sides by a heavy growth 

 of tamarack, Larix americafia Michx. But about a dozen specimens 

 were secured, all of which were of the short-winged form, Af. e. Junius, 

 the measurements of male being : length of body, 18 mm.; of tegmina, 11 

 mm.; of hind femora, 11.5 mm. 



When disturbed they gave several short, quick leaps, and then 

 burrowed as far as they could into the dense mass of sphagnum moss 

 which everywhere covered the bog.

 This is a western species which has not heretofore been recorded 

 east of Kansas and Iowa. According to Bruner, it ranges from North 

 Dakota to Texas, and west to Yellowstone, Montana. He also states 

 that it is increasing rapidly in numbers, and is likely in places to become 

 a serious pest. 



It is one of the most common grasshoppers about the south shore of 

 Lake Michigan, occurring in company with M. atlaiiis (Riley); Sphara- 

 gemon wyotningensis (Thos.), and others over a large part of the sandy area 

 within five miles of the lake. It seems to prefer such barren localities to 

 those more promising in plant food, since Bruner mentions its partiality 

 for " old breakings and well-fed pastures of many years' use." 



To a cursory observer angustipennis bears a general resemblance to 

 atlanis (Riley), but may be readily distinguished by its blue tibis., the lack 

 of a notch at the apex of the last abdominal segment of the male, and the 

 different shape of the male cerci. The dark spots along the middle line 

 of the tegmina of the Indiana specimens are larger and more numerous 

 than one would expect to find after reading the descriptions of Dodge
