April, '13] BRITTOX. WALNUT WEEVIL 199 



one side of the stem, but usually it tunnels downward from the terminal 

 or from an axillary bud being concealed all the while. 



The frass is retained at the entrance of the burrow and being fastened 

 to leaves, helps to form the nest where pupation occurs, and which is 

 the most conspicuous evidence of the presence of the bud moth. The 

 frass is never exu'ded laterally from the burrow as is the case with the 

 walnut weevil. 



The bud moth does about as much damage to the Persian walnut 

 as does the weevil, and like that- species can be controlled by spraying 

 with lead arsenate. In fact, the same treatment is effective against 

 both insects. Probably the winter is passed in the larval stage, though 

 this point is not settled. 



The bud moth may prove to be Aa'ohasis caryce Grote or a new 

 species. 



Early in the summer of 1910 my assistant, Mr. B. H. Walden, col- 

 lected in a blackberry plantation near New Haven some adult saw- 

 flies which Dr. A. D. MacGillivray pronounced a new species. In 1911, 

 he noticed that some of the plants in the same field had been defoliated 

 by saw-fly larvae, but no a^lts were reared that season. In 1912, 

 additional material was gathered and the adults reared from the larvse 

 proved to be identical with those collected in the same field two years 

 before and were described by Dr. MacGillivray in the Canadian Ento- 

 inologist Vol. XLIV, October, 1912, page 297, as Pamphilius dentatus. 



The eggs are laid in rows on the leaf -veins the first part of June. 

 The eggs soon hatch and from fourteen to seventeen days are necessary 

 for the larvse to reach maturity, when they go into the ground and 

 remain until the following spring before pupating. The adults appeal* 

 the" latter half of May. The larvse spin threads by means of which 

 they draw a portion of the leaf over themselves forming a protecting 

 tube in which they feed. One tube may serve as a nest for several 

 larvse or it may contain a single occupant. The habits are quite 

 similar to those of the peach saw-fly, Pamykilhis jjersicum MacG. 

 studied by Mr. Walden in 1907. 



Detailed accounts of these studies together wnth such other facts as 

 are known about, the walnut w^eevil, walnut bud moth and the black- 

 berry saw-fly, may be found in the twelfth Report of the State Ento- 

 mologist of Connecticut, which is Part III of the Annual Report of 

 the Agricultural Experiment Station for 1912. 



At the conclusion of this paper the business session was resumed, 

 after which the meeting adjourned. 



The following papers were read by title and in accordance with the 

 practice of earlier years are included in the printed proceedings.
