THE CANADIAN ENTOMOLOGIST. 113 



Lecontei is found in dry situations. Sandy fields or the edges of 

 drifting sand among sparse vegetation are its favourite spots. It is found 

 in company with Manitoba, veniista and tranguebarica, but nowhere 

 commonly. The new brood appears in August, and they begin to excavate 

 their winter quarters early in September, being one of the first tiger-beetles 

 to disappear. The burrows are nearly always made in very small open- 

 ings, not more than a foot or so wide, surrounded by weeds, etc., being 

 the least open locality of any of our forms or species, with the possible 

 exception of Montana. The average depth of hole of a number measured, 

 from the entrance, was i6 inches, the deepest being 22 inches and 

 shallowest 10 inches. The beetles appear again in the spring in April, at 

 about the same time as venusta, and disappear late in July, about a week 

 before the new brood appears. This form has been seen feeding upon 

 cutworms. 



C. punctulata, Oliv. — -.\ summer species. Appears late in June and 

 dies off towards the end of August. At Aweme it is found on old trails 

 and on prairie where the grass is thin. Appears to be confined to a few 

 spots, vi^here it is usually plentiful. 



The larvae were found in holes on the prairie in small mossy places 

 between clumps of grass in dry situations, at an average depth of 21 inches, 

 the deepest hole being 26 inches and the shallowest 18 inches. Most of 

 the holes at this date (Oct. 7) were filled up tightly near the top, and again 

 about four inches lower down, so that it was very difficult to push a grass- 

 stalk down them. As with other species, the larvae*°greatly exceed the 

 beetles in numbers. 



C. pHsi//a, Say. — This species is taken by Mr. L. E. Marmont, of 

 Rounthwaite^ which is only about 12 miles from Aweme. It occurs on 

 roads and bare spots where the land is of a very black colour. Mr. 

 Marmont takes pusilla in July and August. One he collected as late as 

 the 24th of August. No sign of the beetles could be found in June, and 

 this fact, combined with the general appearance of the insect, leads me to 

 the conclusion that it is probably a summer species that dies at the 

 approach of winter. 



Pusilla has also been taken by Mr. .\. W. Hanham at Bird's Hill, 

 near Winnipeg. Mr. Hanham says, from his experience, pusilla never 

 flies, but runs very rapidly, "easily disappearing off the trail into the long 

 grass and so away." He adds that he only took two or three at the most. 

 Mr, Marmont on one occasion caught a specimen in a pail of milk.
