Lauva. 



Tlu' larva wlicii it escapes from the egg is a delicate 

 while ui-iib about 1-25 of an inch long,, and without legs. 

 (^Ve Fijjs. '2 and 3.) If it were not for the 

 brtjwn head aii<l mandibles the larva would be quite as 

 incunspicuous as is the egg itself. In tiie scpnires the 

 lai va probably molts but twice while growing, but it is 

 almost certain that in the bolls, and perhaps also in 

 squares, there is also a third molt.

During the warmer parts of the summer it is probable 

 that the larval stage in the squares lasts not over 6 days, 

 but in colder Aveather the period is of course longer. 

 Even frosts do not kill the larva in the bolls, and they 

 may continue their growth and complete their develop- 

 ment after the occurrence of a frost.
