disease generally attacked lame at a certain definite stage in their de¬ 
velopment. In rearing large numbers of Lasiocampa ijuercus, he had 
noticed that when many in the penultimate skin were dying, the 
forward lame of the same brood which had reached the last stage 
were not affected. 
Note ox Larva of Eutricha quercifolia. —Mr. A. W. Mera found 
that the larva of Kutricha quercifolia discharged a quantity of strong¬ 
smelling fluid before pupation. On one occasion when he was breed¬ 
ing this insect he had seen that as soon as the largest larva; had 
pupated the rest of the brood sickened and died. This fact he attri¬ 
buted to the smell of the fluid referred to. Mr. V. Eric Shaw bore 
out Mr. Mera’s experience with this insect.
