THE CANADIAN ENTOMOLOGIST. 



long and irregular burrow, measuring in length 2.6 cm. It entered the 

 earth, of course, head first, and burrowed in a direction slightly inclined 

 from the horizontal for a distance of 1.5 cm. Then abruptly turning 

 downwards in a direction perpendicular, it burrowed for a distance of a 

 single centimetre. At this point she died, apparently from exhaustion. 

 Another female was observed to enter the burrow while she worked, but 

 retreated upon finding it occupied, On March 31st the body was 

 extracted with a pair of forceps ,; it was decomposing, and readily fell to 



pieces. Above the bend 

 the burrow was 6 mm. 



wide, and from thence 

 down 4.2 mm. Its en- 

 trance was barely notice- 

 able. It is shown in 

 outline at figure 15. 



e. — Entered the soil 

 during the evening of 

 March 25th, and eggs 

 were found deposited on 

 the morning of the 26th, 

 about 2 cm. directly be- 

 low the surface. They were in a more or less regular mass, most of them 

 placed in rows on end against the glass of the jar ; a few were placed flat 

 against the side of the jar. The mass was at the extreme bottom of the 

 vertical burrow. The latter was 6 mm. wide. 



The parent was directly above the egg-mass, the head, obviously, up, 

 and but 5 mm. beneath the surface. The entrance to the burrow was 

 inconspicuous, the upper half of the burrow itself being filled with loose 

 earth pushed into that part of the burrow during excavation. 



Finally the parent was disturbed with forceps, in order to find its 

 relative position in regard to the egg-mass. Thirty minutes afterwards, 

 evidently on account of this disturbance, it crawled from the burrow and 

 made attempts to escape. It was perfectly fresh in appearance. After 

 wandering through the grass for a while, it went to the entrance of its 

 burrow and made long and persistent efforts to re-enter, but in vain. By 

 the following morning it was resting in the grass, very weak ; fifteen hours 

 afterwards it died.
