single one in coll. Tepper as genuine, while conceding elsewhere that Mr. 

 Morrison was very liberal in labelling specimens as " types." To conclude, 

 in the Synonymic Catalogue the locality for carnea, Mount Washington, re- 

 appears ! On whose authority if not on mine based on Morrison's speci- 

 mens ? What has happened between the Revision and the Catalogue ? 

 Has Prof Smith seen my specimens sent by Morrison and found them 

 really carnea? In the Synonymic Catalogue several oi xa^y Agrotis species 

 are reinstated, and perhaps finally my determination of these two Alpine 

 forms may gradually come to be acknowledged. Where an examination 

 of my collection has resulted in establishing my determinations so very 

 largely, it seems hardly worth while to pursue the subject further. There 

 remain but a few cases of specific detc-mination where I am still of a 

 different opinion from the author of the Synonymic Catalogue, and I 

 reserve my views on these until a proper time. 



Agrotis exsertistigma. 



This species was described by Mr. Morrison on material furnished by 

 me and credited to me, and I figured, in the Buffalo Bulletin, the speci- 

 mens returned as " types " of Exsertistigfua by Mr. Morrison. But 

 it appears that one of my specimens was not returned me, that this 

 specimen, also marked as " type" of exsertistigma^ found its way into Mr. 

 Tepper's possession, and that this specimen belongs to a species after- 

 wards described by me as ohservabilis. It may be truly said that Mr. 

 Morrison's original description was totally inadequate, and that therefore 

 the species should remain as figured and determined by myself. There 

 is nothing to prove the Tepper specimen the genuine one, and mine not 

 genuine. My publication was the only sufficient one. Probably, almost 

 certainly, Mr. Morrison considered them all the same, in which case my 

 determination was decisive. If Mr. Morrison considered my specimens 

 credited to me and Mr. Tepper's one species, I was free to determine one 

 as exsertistigma and re-describe the other (of the existence of which in 

 Mr. Tepper's collection I was, however, ignorant). I think, with justice, 

 my original determination should prevail. But my original determinations 

 have been overturned by Prof, Smith ; only this author has overlooked 

 the fact that his new name for my exsertistigma, viz., con/ttsa, must fall 

 before Morrisonistigma, proposed by me in Buff. Bulletin. 



Thyatira anticostiensis. 



I would draw attention to the fact that this form of T. pudens, Guen., 

 taken by Mr. Wm. Couper on Anticosti, is described by me. Can. Ent,,
