324 THE CANADIAN ENTOMOLOGIST. 



Others were in all probability so, as the sexes were then freely copulating. 

 Oviposition had taken place by the following morning (25th), in two cases 

 the females having burrowed to a depth of two centimetres. They were 

 still within the burrow, apparently going deeper into the earth. 



By the afternoon of the 25th two other females were digging along 

 the sides of the jar ; one was on its back, a centimetre below the surface, 

 the other going head first and about 7.5 millimetres beneath. Four females 

 were thus below the surface ; two of them had deposited, while the other 

 two were still burrowing. Four others were then crawling restlessly about 

 in the dense grass, making futile efforts to enter the ground. A fifth, or 

 the ninth, was found on its back dead, its head buried in the earth. 



By the morning of March 26th six females had deposited their eggs, 



four during the night just passed ; the seventh died before finishing its 

 burrow. The eighth had not as yet succeeded in penetrating the soil ; 

 after doing so it died in its burrow. 



a.— This female oviposited in the early morning of March 25th, or 

 less than eighteen hours after confinement. It was lying in a doubled-up 

 position, in an apparently closed earthen cell, the egg-mass to one side. 

 The body was nearly vertical, the head below, the insect lying on its back 

 to one side of, and slightly beneath, the egg-mass. To all appearances it 

 was dead. The entrance to the burrow at the surface of the ground was 

 unnoticeable, filled as it was with loose soil particles. No movements of 

 the body were afterwards observed, and it is evident that the insect died a 

 few hours after deposition. By March 30th the body was decomposing, 

 and very moist. 



b. — Oviposited in the early morning of March 25th, or less than 

 eighteen hours after confinement. After oviposition the female lay in a 

 cramped position, in a cell similar to that of the preceding. The body 

 was vertical, inclined somewhat, and with the head above. The insect 

 was apperently dead. The entrance to the burrow was not noticeable. 



No further movements of the body were detected, and six days later 

 the body was covered with the spore-bodies of a fungus. By the 9th of 

 April it was badly decomposed. 



c. — On the afternoon of March 25th this female was found in an 

 inclined burrow, on its back, about two centimetres beneath the surface. 

 It was scooping the earth over its head by means of its fossorial anterior
