had all been taken by him about the lower branches of Ostrya 

 Virginica in July and August last. 



Mr. Baldwin exhibited a specimen of the West Indian moth 

 Melipotis fasciolaris taken by him in Otawa last summer and read 

 a note upon its capture. 



Mr. Metcalfe showed 13 species of orthoptera, all taken at 

 Ottawa. 



Mr. Halkett showed some parasitized pupae cf various kinds 

 from his collection. 



Mr. Wilscn gave an account of the country he was exploring 

 last summer in the Temagami district. 



A copy of Dr. E. P. Felt's sumptuous memoir Insects Af- 

 fecting Park and Woodland Trees, Volume 1, was laid on the 

 table and was much admired by all present. J. F. 



Held at Mr. Gibson's, 20th April. Messrs. Halkett, Flet- 

 cher, Harringr.n, Keele, Metcalfe, Baldwin, Newman and Gib- 

 son present. 



Mr. Halkett exhibited living specimens of the nymphs of 

 some May-flies and Stone-flies which he had collected from the 

 Rideau river. He said that he had found these in thousands, 

 near St. Patrick's Bridge, swimming up the river against the 

 current. He also showed one of the curious cases, with the larva 

 inside it, of a caddis-worm. 



Dr. Fletcher spoke cf an interesting occurrence at Ottawa, 

 in very destructive numbers, of a tineid caterpillar. This min- 

 ute larva is at present working inside the tips of white cedars, 

 killing many twigs and giving the trees a very unsightly and un- 

 healthy appearance. Specimens of the work of this minute in- 

 sect were examined. Dr. Fletcher also showed some living 

 parasites, Pteromalus puparum, reared from the chrvsalids of the 

 Common White Cabbage Butterfly. Mr. Harrington mentioned 

 that he had found the cases of Coleophpra laricella in large num- 

 bers on wild trees of Larix Americana at several places in the Ot- 

 tawa district. A living specimen of Meloe niger, one of the first 

 insects to appear in the spring, was also shown by Dr. Fletcher.
