close around first and afterwards reaching out to gather it from 

 as far as could be conveniently reached by stretching out for it 

 with the hind legs. This work was done very thoroughly so that 

 no sign other than a slight elevation remained to indicate where 

 the eggs had been laid. The hind legs are generally used alter- 

 nately for this work and are applied with additional vigor as the 

 task proceeds. Then haying completed their work the locusts 

 either hop or fly quickly away. The egg-sacks were of the usual 

 curled shape with a neck of glutinous matter that did not quite 

 reach to the surface of the ground. They contained 24 and 25 

 eggs, respectively. 



Camnida peliucida Scudd. Several examples were observed 

 ovipositing near Boissevaine, Man., on September 20th. The 

 land was dry and hard, and the vegetation thin with bare spots 

 between. Many individuals were present. The egg-laying habits 

 of this species are very similar to those of Arphia, described above. 

 One example took 23 minutes to conclude her operations from the 

 time when she w^as first observed with her abdomen inserted. 

 She then carefully filled in the cavity using both hind legs for 

 that purpose — the egg-sack contained 18 eggs. 



Dissosteira Carolina Linn. This large species can be found 

 ovipositing without much difficulty during the month of Septem- 

 ber. For that purpose it seeks soil which is comparatively free 

 from \-egetation and situations that are fully exposed to the sun. 

 A large, yellow female was found on September 19, 1915, having 

 just completed working her abdomen into the soil, from which 

 time she took 48 minutes to finish egg laying. The hole was then 

 covered by use of the hind legs which were applied quite vigor- 

 ously, the loose earth being chiefly drawn towards the insect from 

 behind. This egg sack was almost two inches long, of which rather 

 more than a third consisted of neck. It contained 42 eggs. A 

 second example observed ovipositing on September 22 occupied 

 an hour and 19 minutes, and took three extra minutes to cover 

 the egg cavity. This latter operation was done entirely with the 

 left leg. Three others were found on September 28, one of which 

 took an hour and 21 minutes from the time she was first noted 

 with her abdomen in the soil. In these instances both hind legs 

 were used in covering the egg chamber.
