"220 THE CANADIAN ENTOMOLOGIST. 



grown. He found a lot on chestnut, two of which pupated and emerged 

 the same fall, the others remaining in pupa until the following spring. 



Mr. Osborn stated that his experience with io at Ames was similar to 

 that described by Mr. Kellicott, and he asked whether Asopia faj-inalis 

 ever occurs in clover hay. He at one time found the imago very abun- 

 dant where clover was badly infested, but he could not say the larva was 

 that oifarinalis. No one present was able to answer. 



In reply to a question, Mr. Webster said he had seen the Cecidomyid 

 larvae feeding on the Aphids. 



Mr. Ashmead said the habit is not uncommon. He has bred preda- 

 ceous species himself, and Mr. Fletcher has recorded a similar occur- 

 rence. 



Mr. Howard thought the habit could scarcely be called a common 

 one ; he recollected only two European records of that character. 



Mr. Lintner spoke on the occurrence of an onion pest at Canastota 

 and vicinity, in Central New York, during the month of June. The pest 

 was reported as a dark coloured caterpillar of a maximum length of an inch 

 and one-fourth, feeding on the plants above ground, overrunning large 

 fields of onions in the muck lands north of Canastota, and consuming not 

 only all of the onion tops but other vegetation also. From the account 

 given, the caterpillar was believed at first to be the species of cut-worm 

 that in the spring of 1885 proved so exceedingly destructive in the onion 

 fields in Goshen and vicinity^ in Orange County, N. Y., as recorded in 

 Prof. Riley's Report to the Department of Agriculture, for the year 1885, 

 viz. : Agrotis messoria. Comparison of the caterpillar secured later, 

 showed it to be a different species, which, on being carried through its 

 final stage, confirmed the identification of it which had been made from 

 Prof Forbes's admirable figure in his 15 th Report, as Agrotis ypsiloti. The 

 moths emerged from the pup?e in the early part of Juiy. 



It was not possible at the time to visit the infested locality to note 

 particularly the habits of the cut-worm and the amount of injury inflicted 

 by it, nor could any definite or satisfactory information be obtained by 

 correspondence, for the attack ceasing with the pupation of the larvse, all 

 further interest in it on the part of the onion growers seemed to be lost. 



Mr. Lintner also read a letter from Mr. Geo. F. Shepley, asking for 

 information concerning an insect which had bored galleries in the pine 

 boards and in the linen contained in a closet, and had done much injury 

 to the fabric. He asked whether any members recognized the attack.
