40 • THE CANADIAN RNTOMOLUGIST. 



Ottawa, Dec. 14, 1882. 

 My Dear Si?.- In the last Kmu.moi.ooi.st. at page 198, Mr. Fyles 

 contributed a note on a gall mite of the Nettle tree. The insect referred 

 to is undoubtedly Prof. Riley's Psylla cc/t'ufis-inainma. of which I exhibited 

 the galls and pups at the last Annual Meeting of the Society, and of 

 which I have already sent you an account in a paper on " The Cicadfe 

 and their Allies," for the Annual Report. J notice that Mr. Fyles found 

 his galls to be monothalamous. and this agrees with Prof Riley's descrip- 

 tion. I have found, however, in examining a large number of specimens, 

 that many contamed 2. j;, and in one case even 4 pupa^. The occurrence 

 of Celtis occiilcittalis at CoA\"ansville is very iiueresting from a botanical 

 point of view. In this locality it is very uncommon, although from its 

 resemblance to the Elm, it has probably been frequently overlooked. It 

 grows to the size of a small tree from 30 to 40 feet in height, with a 

 diameter of from 12 to 18 inches. In ^^'estern Canada 1 believe it is a 

 common tree, and I should be glad to learn whether it is there attacked 

 by this Psylla to the same extent it is here. In some of the galls I 

 examined I found the larva; of apparently two different species of parasitic 

 Hymenoptera. j. Flktchkr. (Jttawa, Ont. 



Editor Can. Ent. — Dear Sir : 1 am sure your readers were pleased 

 at your printing the pretty lines on a winter butterfly, which Mr. Fletcher 

 took the trouble to send. (See ]). 219, vol. xiv. ) I remember very many 

 years ago. in Januarv. finding a hibernating Va?u'ssa Antiopa in the 

 garret of our Staten Island farm hou.se. It hung from a rafter and seemed 

 almost dead. I placed it on a brick flue, which was liardly warm, but it 

 did not revive at the time. Some few days after, the weather having 

 become milder. 1 searched for it and found it where I had laid it. still on 

 its side, with the legs drawn in. But on touching it, the wings suddenly 

 unclosed, the insect took to flight, and. the window being open, it escaped 

 into the winter sun^^hine. Some years after I found three or four speci- 

 mens of Pyraiiu'is Atalanta under the same circumstances, all close 

 together, hanging to a rough rafter and perfectl}' torpid. On l)eing placed 

 in a warm room the}- revived in a short time and 1 allowed them to 

 escape. As early as warm February days I have met the Cambenvell 

 Beauty and Admiral, in solitary state, on the wing. The south side of 

 Staten Island soon gets warmed by the Spring sun. and is a good collect- 

 ing field for the entomologist. A. R. Grote.
