ilie genus Gryllus. As the mole crickets crawl ratlier than leap, the 

 hind femora arc hut little enlarged, and are alwaj^s shorter than the 

 pronotum. The hind tarsi are short, seldom exceeding half the 

 width of the pronotum. But one species occurs in Indiana.

The northern mole cricket has been taken by the 

 writer in Marshall, Starke, Kosciusko, Putnam, Clin- 

 ton, Vigo, Tippecanoe, Marion and Monroe counties, 

 and doubtless occurs throughout the State, as it is 

 found over the United States and Canada east of the 

 Rocky Mountains. About one-third of those noted 

 in the State are of the long winged form. On one 

 occasion a log deeply buried in the sand on the 

 southern shore of Lake Maxinkuckee was overturned 

 and nine specimens were secured. Of these, however 

 winged and three short winged. 



In the moist mud and sand along the margins of the smaller 

 streams and ponds the runs or burrows of this cricket, exactly like 

 those of a mole though much smaller, can in late summer and early
