226 THE CANADIAN ENTOMOLOGIST. 



Friday, August 22nd. — The Club met at 8.30 a. m. Dr. Weed pre- 

 sented a short paper on the habits of Lixus concavus. 



As reported in the bulletin of the Ohio Ex. Station, Mr. Alwood had 

 found this insect injuring the stems of rhubarb. During the past summer 

 he had bred it from all parts of the stem of the common curled dock. 



Prof. Alwood stated that he had observed the larvae of Gortyna nitela 

 eating those of Lixus. 



Dr. Weed read a paper upon the habits of Psephenus Lecontei. 



Prof Webster and Mr. Fletcher also spoke on the habits of this beetle. 



Prof Hargitt read a note upon a large foliaceous gall which destroyed 

 the tips of the stems of various species of Soiidago at Bloomington, 

 Indiana. In many instances as many as ninety-nine per cent, of the flower 

 stems had been destroyed. 



Prof Hargitt read a note upon the Canker Worm. He said : " My 

 attention was drawn to an orchard near Oxford, Ohio, which, for three or 

 four years, had been seriously affected by this pest. In May, 1890, I 

 went to examine the orchard and found it thoroughly over-run by the 

 larvae, many of the trees being actually dead, and several others in a very 

 weak condition. The orchard, viewed at a distance, had the appearance 

 of having been burned, the leaves being brown and dead. The trees 

 were most attacked upon the outer rows, particularly those adjoining a 

 wood. I recommended spraying with one of the arsenites, but it was too 

 late for the present season. I observed several small birds in the orchard 

 actively engaged in feeding upon the larvte, amongst them the cedar bird, 

 blue bird, summer warbler, chipping sparrow and field sparrow." 



Prof. Hargitt also read a note upon C er mat ia forceps. He had found 

 that this Myriapod had become abundant in houses and the college 

 building at Oxford. Ohio, during the past two or three years. He had 

 experienced the same difficulty in keeping the insects alive in captivity, 

 as was mentioned by Dr. Lintner in his 4th Report. He had succeeded 

 in keeping them for several days and inducing them to take prey by 

 keeping them in dark quarters in a tin canister during the day. When 

 so confined they had fed freely upon house-flies, and other insects sup- 

 plied them. 



Prof. Webster spoke of the predaceous habits of C. forceps, and its 

 special fondness for the Croton-bug (Ectobia germanica).
