in all the Northern United States." I have been unable to procure speci- 

 mens from further west than Ontario or Illinois. In the Staudinger 

 Catalogue, Lapland, Northern Scandinavia, Sajan-Geibet (Siberia), Amur 

 and North America are quoted as localities for " var. hypophlceas," and 

 some that I have bearing labels of some of those Old World localities would 

 pass anywhere as North American specimens, amongst which there is also 

 an occasional tendency to lose the spots, and so assimilate the typical 

 European form. Besides having more pointed wings, the majority of my 

 European and Asiatic specimens show a more decided tendency to develop 

 tails in the secondaries than either the old or new forms of our continent ; 

 and it is a fact well worthy of observation that in some, though not all, of 

 those most closely resembling ours in other respects, this tendency is 

 least. Hypophlceas is recorded by Capt. Gamble Geddes as occurring in 

 the region of the Crow's Nest Pass, in Southern Alberta. Dr. Fletcher 

 tells me that if any such specimens were preserved they should be in the 

 Geddes collection at Ottawa, but that he is unable to find any. With one 

 or two small females only to hand, if the spots were unusually well 

 developed, arethusa might have been passed as hypophhzas even by one 

 well acquainted with that species without comment. The name I have 

 chosen is purely fancifiil. 



GEOMETRID NOTES— No. 2.

In 1S73 Dr. Packard described a species (5th Rep. Peabody Acad. 

 Sci., 1878) under the name of Cleora pellucidaria, having before him two 

 males, one from Maine (Pack.) and the other Albany (Lintner). If my 

 memory serves me correctly, I saw the Maine specimen when at Cam- 

 bridge in going over his collection. Shortly afterward, through the 

 kindness of Mr. D. H. Haight, I received a female of the same species, 

 taken near his home at Copper Cliff, Ont., Sept. 9, '04, and, in a recent 

 visit to Albany, N. Y., found in the Lintner coll. the original co-type 

 described by Dr. Packard, bearing a label in his handwriting. In the 

 Monograph, page 453, he refers to this species, having a doubt at that 

 time of its validity. The species is a good one, and differs from settii- 

 clusaria, Walk., by its larger size, stouter build, its uniform soft gray 

 colour, and by having the front a darker smoky hue, while in semidusaria
