The Sumach gall. Fine specimens of the curious and pretty 

 gall which is sometimes found beneath the leaves of the Stag's horn 

 Sumach, have been sent from Nictaux Falls, Annapolis county, N.S., 

 by Prof. A. H. Mackay. This gall, which varies very much in size and 

 shape, but is generally somewhat spherical and from \ to i inch in 

 diameter, is formed by one of the gall-making plant lice beneath the 

 leaves of both the Stag's horn and Smooth Sumach. The colour is the 

 same as that of the leaves, and like the latter, turns to a brilliant scarlet 

 in the autumn. 



In the American Entomologist for 1869, Prof. Walsh says: 

 "Early in spring, as we have been informed by Dr. Manlius, each gall 

 contains but a single wingless mother louse with numerous larvae." At 

 this time of the year, when the galls drop to the ground, they are found 

 to be little more than hollow bladders filled with enormous numbers of 

 winged plant lice. Numerous specimens were collected at Kirk's Ferry 

 last year and attracted much attention ; some of the largest galls 

 resembled small tomatoes. The insect which causes these curious 

 excrescences is known by the name of Pemphigus rhois, and belongs to 

 the Aphidse or Plant lice. 



Eacles imperialis. I have received a specimen of this large and 

 beautiful moth from Mr. T. W. Ramm, of Ross Mount, Northumber- 

 land county, Ontario, who writes as follows concerning its capture : 

 " I am not certain of the date, but it was at the end of June or the 

 beginning of July, when I found two specimens of the Imperial Moth 

 mated on a piece of an old log, on the side of the Port Hope and 

 Peterboro gravel road, on Lot 35 in the 7th Concession of the Town- 

 ship of Hamilton. This is the last Lot, and the Concessions here 

 number from the shore of Lake Ontario and are one mile and a quarter 

 each. I had never seen the moth before, that I remember, in a residence 

 here of 32 years." 



Catocala relicta. Mr. Ramm also sent, under date of Sept. 

 1 8th, a specimen of the above named handsome moth, which he had 

 taken two days before. The colouring of this moth is chiefly white, 

 with a few black marks, and Capt. Geddes has recorded an interesting 

 habit, with regard to this species, of settling on white trees or other 

 white objects. He has taken several specimens at rest on the white
