116 THE CANADIAN ENTOMOLOGIST. 



that Nemalus ventricosus, Klug, is found at Quebec. The larvae have been 

 very destructive, stripping some of the gooseberry and currant bushes almost 

 before I knew they were there. — G. J. Bowles, Quebec. [This pestilent 

 saw-fly has been more than usually destructive this year in the province of 

 Ontario. It appears now to have spread over the whole Dominion of Canada, 

 as^well as over some of the neighbouring States ; last year we received speci- 

 mens from Mr. J. M. Jones, of Halifax, Nova Scotia. — Ed.] 



American Butterflies and Moths. — (1) Do you know of any work on 

 American Butterflies and Motlis, publishing in numbers in cheap form, like 

 Newman's British Moths and Butterflies, in which every known specimen is 

 figured and described in caterpillar, chrysalis and perfect state, both male and 

 female ? and if not, would not such a work pay ? (2) Would it not be a 

 good plan to begin such a work in the Canadian Entomologist, taking, say 

 butterflies first, each variety in succession, giving scientific and popular names, 

 with wood-cuts of caterpillar, chrysalis, and full grown insect, one in each 

 number till the work is completed ? — J. W. H. Rowley, Yarmouth, Nova 

 Scotia. [Reply by Ed. C. E. — (1) There is no such work being published 

 in parts j but Mr. Scudder, of Boston, Mass., has in preparation an elaborate 

 work on the Butterflies of New England, which will include probably all the 

 Canadian species. It is to contain descriptions, with coloured illustrations 

 of the eggs, larvae, pupae, imagines and parasites, of all the species found in 

 the New England and neighbouring States and Provinces. It must neces- 

 sarily be an expensive work, though no doubt it will be issued at as cheap a 

 rate as possible. It is rather difficult to say whether such a work as Mr. 

 Rowley contemplates would pay in America ; if well got up and made inte- 

 resting and attractive to the ordinary collector it might obtain a large sale, 

 but Entomology has hardly a sufficient number of votaries on this Continent 

 as yet to assure against loss in such an undertaking. As far as a work on 

 the Butterflies alone of North America is concerned, nothing can surpass in 

 beauty and excellence Mr. Edwards' work, now being issued in quarterly 

 parts, but of course it is not a cheap work, each part being $2 50 in U. S. 

 currency, though well worth the money. (2) We should be delighted to 

 carry out such a work in the numbers of the Canadian Entomologist, had 

 we sufficient means to pay for the wood-cuts. If any enthusiastic Entomolo- 

 gist will supply the necessary funds, or give us a sufficient guarantee against 

 loss, we shall be only too happy to do all the rest of the work to the best of 

 our ability.]
