tibiae, passing it over the venter, and from thence out of the burrow, with 

 its slender posterior pairs of legs. Hence its head was at the bottom of 

 the burrow, the body inclined upward. 



Oviposition commenced very early in the morning of the 26th. The 

 eggs were being massed across and around the tip of the abdomen, about 

 1.3 cm. down the burrow, and 1 cm. directly below the surface of the 

 soil. The entrance to the burrow was unnoticeable. 



At g.30 a.m. the insect was in the same position, on her back, the 



body inclined upward, the abdomen highest, the anterior legs stretched 



out beyond and above the head in the position assumed while digging. 



Further extension of the burrow had probably been stopped by masses of 



intertwined rootlets. The eggs were then being placed quite irregularly, 



above and below the caudal half of the abdomen, sometimes in clusters of 



regular rows, mostly simply massed together. The individual eggs were 



placed methodically at the rate of from six to eight per minute, by simple 



movements of the. tip of the abdomen. By this time she had effectually 

 bottled herself within the burrow with eggs, which, as indicated, were then 

 massed directly across the burrow, above, below and in front (caudad) 

 of the abdomen. The burrow itself was not clearly defined, but filled with 

 loose particles of earth, which were also mixed in with the egg-mass. 



By 3 p.m. oviposition had apparently stopped, the period thus being 

 about twelve hours. The position of the body had not changed, but the 

 whole of the caudal half of the body was then nearly covered with eggs, 

 while the wings extended beneath most of the mass, forming a good 

 foundation. The female was thus actually pinned down. The mass itself 

 was broadest at its bottom or base, and extended from one side of the 

 burrow to the other ; it measured approximately 3 mm. (apex), by 4 mm. 

 (base), by 6 mm. (depth). The burrow measured at its greatest width 8 

 mm. The insect's posterior two pairs of legs were extended out and up, 

 the caudal pair crossed. 



The female remained perfectly motionless after oviposition ceased. 

 Gradually moisture gathered about the egg-mass and body, until at last 

 (April I St) both were bathed in it. About April 9th the body com- 

 menced to sink, and was highly decomposed. 



d. — This female was also found burrowing on the afternoon of the 

 ist of April. It was but 1.2 cm. directly below the surface, in a rather
