I have found this cricket in abundance in all parts of Ontario where 

 I have made collections of Orthoptera. In this species the tegmina 

 usually cover about three-quarters of the abdomen in the ^ , and about 

 half the abdomen in the 9 , and in such specimens the wings are absent. 

 This is the form that was formerly known as vittatus. Specimens with 

 wings extending far beyond the end of the abdomen are often met with, 

 however, and are most often seen at night, when they are attracted to 

 light. These long-winged individuals are usually, but not always, females. 

 Blatchley says of this species in Indiana: "During hundreds of days spent 

 in field collecting, not a single specimen of the long-winged form was taken 

 until Aug, I, 1902, when it was found in numbers on the stems of long grass 

 in a marsh bordering Round Lake, Whitley County." This has not been 

 my experience, as I have frequently come across it in the field. On Aug. 

 26, 1 90 1, I found large numbers of this form floating on Lake Huron, 

 about a quarter of a mile from the south shore of the Bruce Peninsula. It 

 was a hot, still day, and many other insects were seen floating in the same 

 manner, notably two other Gryllidse, the tree cricket, CEca?ithus fasciatus, 

 and the long-winged form of Gryllus abbreviatus This species reaches 

 maturity towards the latter part of July, and continues until severe frost, 

 usually in the early part of November. 



Specimens from the south-west appear to average larger than those 

 from the north. My largest ones are from Arner, Essex Co., close to the 

 shore of Lake Erie. 



Localities : Niagara Falls, Point Pelee, Arner, Chatham, Sarnia, 

 Goderich, Southampton, Bruce Peninsula, Owen Sound, Hamilton, To- 

 ronto, Lake Simcoe, Severn River, Lake Muskoka, Algonquin Park, North 

 Bay, Stony Lake (Peterboro' Co.). 



< Mr. Blatchley has called my attention to a small dark Nemobius 

 which he has taken in Northern Indiana, Michigan, and in Ontario across 

 from Buffalo, N. V. I have also taken this form, and I agree with Mr. 

 Blatchley in considering it to be a small degenerate form oi fasciatus. 

 5. Nemobius canus, Scudd.

I have a single $ Netnobius taken at Arner, Ont., which agrees 

 pretty well with Blatchley's description of canus. The head is light
