256 THE CANADIAN ENTOMOLOGIST. 



Mr. Riley exhibited specimens oi Megaphycis'bollii in all stages, and 

 mide some brief remarks on the life habits of the species, which he was 

 led to do by the fact that Mr. Smith had recently bred it from prickly 

 pear in New Jersey. His own specimens had been bred from the fruit 

 of Opuntia in Florida, first received in 1877 from Mrs. Mary Treat, of 

 Green Cove Springs. Fla , and subsequently from Mr. H. G. Hubbard, 

 Crescent City, Fla., in January, 1883. He had had the species marked 

 with the MSB. name Myelois opuntiella, and had had engravings made of 

 all stages for many years : but as he had learned in 1S82 that the insect 

 had been described as Metitera prodenialis by Walker, he had never 

 ]3ublished his description, and the species was subsequently named as 

 Megaphycis boUii by Zeller. According to the law of priority this last 

 name, both generic and specific, would have to give way to Walker's. 

 The breeding of this species in New Jersey gave it a more northern range 

 than had been hitherto recorded. 



As a supplement to the paper which was expected from Mr. Lintner, 

 he further exhibited a box containing specimens of t and ? Phengodes 

 laticollis and Zarhipis riversii, and called especial attention to the larvi- 

 form females. 



He also called attention to the fact that in connection with Mr. 

 Pergande, he had been of late making special collections and observations 

 of Phylloxerce at the request of Mr. Dreyfuss, who was preparing an 

 elaborate work on them. He had found many interesting new forms and 

 manv facts that were new concerning the habits of the gall-makers on 

 hickory. He had also found an interesting species on willow and Nyssa, 

 and stated that the hickory species are much more numerous than had 

 been supposed. 



He also exhibited a box of specimens, with drawings, illustrating the 

 life liabits oi Sphecitts speciasus, which had not been previously recorded. 

 The egg and several larval stages were shown in the specimens. One of 

 the most interesting features is in the cocoon. There is a median band 

 lined with silk, containing curious circular perforations which have the 

 appearance of minute tubes reaching the exterior of the walls of the 

 cocoon with a sort of rim, recalling in appearance stigmata. He was 

 oblic^ed to leave without going into further details, but hoped for an 

 expression of opinion from others as to the object of these peculiar 

 perforations.
