THE CANADIAN ENTOMOLOGIST. 225 



omyid larva on choke-cherry, with habits very Uke those described, and 

 thought it might possibly be the same. 



Mr. Fletcher thought it unlikely that a pear insect would be found on 

 Prunus. It might possibly be found in some allied forms like Crataegus, 

 as is Anthonomus 4-gibbus at Ottawa. 



Mr. Howard gave some notes on 



THE ENCYRTIN^ WITH BRANCHED ANTENN/E. 



He gave a history of the gradual discovery of these aberrant forms, a 

 box of which he exhibited, and explained by means of blackboard figures 

 the nature of the curious antennal modifications. Excellent drawings of 

 the species were also exhibited. 



In response to a question from Mr. Osborn, he stated that one of the 

 species was bred from Bucculatrix ; but that the hosts of the others were 

 not known. 



On motion of Mr. Keilicott, the President appointed Messrs. Kelli- 

 cott. Smith and Howard, a committee to nominate the officers of the 

 club for next year. 



The Club then adjourned until i p. m. 



AFTERNOON MEETING. 



The Club reassembled at i p. m., vvith President Osborn in the chair 

 and twentj'-seven persons present. 



A paper by Mr. Hubbard being called for, 



Mr. Schwarz stated that the communication to be presently read by 

 the Secretary was not an elaborate paper, but a private letter hastily 

 i written by the author while still in the field. The insects mentioned 

 therein had, of course, not yet been studied, and could only be determined 

 by Mr. Hubbard after his return. But on account of the highly interest- 

 ing information it contained, the letter was eminently fitted to be laid 

 before the Club. No previous observations on the insect life in the Hot 

 Springs of the Yellowstone Park seem to have been made, although this 

 interesting locality had frequently been visited by scientific parties. In 

 fact, beyond Dr. Packard's short article in the American Naturalist on a 

 Stratiomys larva from a hot spring in Colorado, he was not aware that 

 anything had been published in North America on the insect fauna of Hot 

 Springs. Further, there was very little recorded of the general insect 

 fauna of the Yellowstone Park, and he even remembered having seen
