LIFE HISTORY OF THE STRIPED CUCUMBER BEETLE 

 WITH A BRIEF ACCOUNT OF SOME EX-

By T. J. Headlee, Manhattan, Kan. 



In this paper it is purposed to give briefly the results of a study of

Egg. In 1907 the first eggs discovered were laid by a caged 

 beetle on July 2d, but it was not until July 16th that they were found 

 in the field. Eggs were last taken in the cages the 7th of August, 

 and oviposition in the field appeared to have ceased some time before. 

 The egg-laying period, therefore, occupies about one month in New 

 Hampshire. 



The eggs are deposited singly or, with equal frequency, in groups, 

 in the soil, usually just beneath the surface, but sometimes on the 

 surface or, again, a considerable distance down. The variation seems 

 to be largely dependent upon the compactness and moisture of the 

 ground. When it was dry and cracked, the beetle was likely to de- 

 posit her eggs on the moist soil in some crevice, but if damp and com-
