of St. Lawrence, N. Lat. 49 ; it also, according to Staudinger, 

 occurs in Siberia ; Gruenee cites it as common in Russia. 

 Agrotis conftua was found by Mr. Couper to be common 

 on Anticosti Island ; it occurs also in Iceland (Staudinger), 

 Scotland (Norman), Switzerland (Gfrote), Prussia ? and France 

 (Guenee).* 



The geographical distribution of the Noctuidse of the Uni- 

 ted States has not been studied. No attempt has been made 

 to assign the species to distinct faunal provinces, although 

 the material for such an arrangement is unquestionably far 

 more ample than with the Phalsenidse. Much of it is unpub- 

 lished, although accessible, if sought for, from the various 

 collectors to be found in nearly every State of the Union. It 

 would prove of essential service if every skilled collector 

 would furnish for publication, authenticated lists of the Lepi- 

 doptera known to him to occur in his vicinity. These, for 

 greater convenience, could be combined into State Lists, simi- 

 lar to that given by Prof. Snow, of the Lepidoptera of East- 

 ern Kansas.f 



The editor of the Canadian Entomologist, in appreciation of 

 such work, has made special request for such lists of the 

 Diurnal Lepidoptera, J and has arranged for their tabulation 

 previous to publication in the pages of that valuable journal. 

 We feel assurance that lists of the Heterocera would also be 

 gladly received and promptly published. 



A very excellent local list, is that given by Mr. Roland 

 Thaxter, in Psyche, Vol. II, pp. 34-38, 80, of collections of 

 Noctuidse, recently made, mainly by himself, at Newton, 

 Mass., and vicinity. It enumerates three hundred and forty- 

 seven species, and is accompanied with statements, in an 

 abbreviated form, of the comparative abundance of each, 

 month of appearance, means of capture of all (whether at light, 

 at sugar, or at rest), and the food-plant of the larva of a num- 

 ber. 



In Yol. VII of the Canadian Entomologist, pp. 3 and 21, 

 Mr. George Norman records his captures of Noctuidae at St. 

 Catherines, Ont., during the year 1874, citing one hundred and 

 seventy-four species, with their dates of capture and compar- 



*For the determination of these species, and of many others, I am indebted to the kind 

 services of Mr. Grote, always most cordially rendered.
