THE CANADIAN ENTOMOLOGIST. 327 



The eggs from this female were carefully removed from the soil and 

 counted. They readied a total of 2,604. 



f. — Began to burrow during the evening of March 25th, and eggs 

 were found on the following morning, or about fifteen hours after starting 

 to dig into the earth. The burrow was vertical. 



g. — This female was crawling over the surface of the soil late in the 

 afternoon of March 25th, searching for a suitable spot at which to enter. 

 Accordingly a hole eight millimetres in diameter was made for her by 

 pushing the blunt end of a pencil into the earth. 



On the morning following eggs were found deposited in two masses, 



one at the bottom of the hole, and the other on the surface of the soil at 



its edge. The hole was eight millimetres deep. The parent was observed 



to crawl into the hole several times, but was apparently dissatisfied with 



it, and deposited no more eggs. Instead she made many efforts to enter 



the earth elsewhere, but failed. On the morning of March 28th she was 

 very weak, and during the afternoon died. 



No attempt to cover the eggs was made, though after they were dug 

 up some were found to have been buried in the earth at the bottom of the 

 pit. There were 3,007 eggs in the combined masses. 



h. — Although not succeeding in getting into the earth, this individual 

 scattered her eggs in small masses through the grass. It died on the 

 morning of March 17th, in a position indicating a last effort to get beneath 

 the soil. The eggs, exposed to the air, shriveled up in a very few hours. 



i. — This female died soon after confinement. Made persistent 

 attempts to enter the earth. 



B. — At 1.30 p.m., 29th March, six females were taken from the two 

 trees and confined as in foregoing, the jar containing compact loamy soil. 

 They continued to wander through the whole of the next day, and by the 

 morning of the 31st none had as yet succeeded in entering, though trying 

 hard to do so. One was then found dead, in a slight depression, near 

 several hundred of her eggs, in a mass on the surface of the soil. The 

 remaining five were showing evident signs of weakening, and, as expected, 

 were on their backs dead on the morning following. A few eggs were 

 scattered here and there over the surface. They soon dried up. 



Although these females freely entered loose earth present, getting 

 some distance beneath, they refused to oviposit in such places, and always
