THE CANADIAN ENTOMOOGIST. 29 



by Mr. Walsh (Proc. Ent. Soc. Phil, T. iii., p. 608, after the statements 

 1. c, T. vi., p. 286) on Bdtila nigra and CepJialanthns occide?italis, both 

 probably Cephaloneon. Further, after the Hst of Acarideous galls given 

 by Mr. Walsh (1. c, T. vi., p. 285-2S6), 3 on Ulmus, i Populus, several on 

 Quercus, i Juglans, i Negundo — in all 13 species not seen by me. Of 

 these 68 galls, 56 are Pleurccecidia. 



The 68 Phytoptus galls known from N. America belong to 42 species 

 of plants, to 33 genera, and 23 families. Primus has 7 different galls, 

 Acer 5, Quercus at least 4 ; all other plants have less, mostly one gall. 



It is obvious that this list is only a beginning of the knowledge of the 

 Phytoptus galls in N. America, when we look on the large number of 

 species discovered in Europe since more attention is given to them, prin- 

 cipally by the untiring efforts of Dr. Fr. Thomas. 



ENTOMOLOGICAL NOTES. 



BY J. G. JACK, CHATEAUGUAY BASIN, QUEBEC. 



The following notes on the habits of several insects are from a record 

 of entomological observations kept during the past four years, and although 

 imperfect, they may serve as a hint to others to pursue observations in the 

 directions indicated. 



During the past season few unusual specimens were taken and very 

 few notes made. Diurnal Lepidoptera (with the single exception of P. 

 cardui, which had been rare for some years) were unusually scarce. 

 Fieris rapce is becoming less numerous every year, owing, probably, to its 

 many parasites. Moths were not so abundant as usual, and the only cap- 

 ture worthy of notice was the re-occurrence of Aletia xylina Say (the 

 cotton-worm moth), a single good fresh specimen of which was taken 

 October 26th, in the woods, among leaves near a butternut tree. There 

 had been severe frost the night before, but the moth was quite lively when 

 found. Looking through my note book, I find the following entries 

 regarding this insect : — 



"October ist-i5th, 1881. Yonnd. Aletia xylina Say quite common, 

 especially in open barrels or heaps of decaying apples left in the orchard." 



" Sept. 21, T882. Aletia xylina Say taken at decaying fruit."
