locust (Robinia psendacacia) . The wound thus produced 

 results in a small dead area surrounding the cell, which was 

 found to extend through the thick inner bark to the wood 

 itself. The hibernating larvae are very small. Normally but 

 one egg is deposited by the beetle in a place, instead of clusters 

 of from 4 to 9 as stated by Gen. H. A. S. Dearborn, who was 

 the first to record the more important facts in the life history 

 and habits of this insect. The beetle selects healthy spots for 

 oviposition, thus making the injury more extensive than it 

 would otherwise be. The dead portion of the plant tissue 

 around the larval cells resembles somewhat the bark killed by 

 the pear blight and seems to be of a similar nature. 



Mr. Caudell reported that assistants of Mr. A. H. Kirk- 

 land, Superintendent for Suppressing the Gipsy and Brown- 

 tail Moths, had lately taken from 25 to 30 cocoons of a Japa 

 nese limacodid moth (Cnidocampa flavescensWalk.) near Cape 

 Cod, having mistaken them for those of the gipsy moth. This 

 species was introduced into North America many years ago, 

 but has not been taken before in the Cape Cod region, so far 

 as known. In this connection Mr. Caudell stated that Doctor 

 Dyar had experienced considerable difficulty in inducing bred 

 limacodid moths to mate in captivity. Mr. Knab stated that, 

 as regards chrysomelid beetles, most of those that emerge in 

 the fall do not mate until the following spring, and he thought 

 that some similar explanation might account for this failure 

 to mate in the case of the limacodids. Professor Quaintance 

 stated that he had a record for the plum curculio in which 

 specimens mated in summer almost immediately after emerg 

 ence from the pupa, and larvae therefrom were reared almost 

 to maturity. Doctor Hopkins stated that in Europe bark wee 

 vils of the genus Pissodes do not mate until a year after they 

 emerge and are known to live three years and to oviposit each 

 year. Mr. Knab stated that he had reared the larva of the 

 cerambycid beetle Orthosoma brunneuni Forst. to the pupa in 

 an old railroad tie. Doctor Hopkins stated that larvae of the 

 locust borer (Cyllene robimce Forst.) develop, transform, and 

 emerge from a gallery little more than twice the length of the 

 full-grown larva. Larvae under dry conditions completed their
