tural character should refer it to a known species with certainty. 

 Now I wish to call attention to just one thing: in all the discus- 

 sions on this matter so far as the Lepidoptera are concerned, 

 everything seems to have gone on the question of color and 

 markings; factors which within a limited range are quite constant 

 and worthy of high rank, but which above all other matters are 

 subject to variation and to aberrations. I always examine an 

 insect for structural characters before I determine its rank in any 

 work that I do. I have never yet found, anywhere, two species 

 that are entirely alike in structural characters, and where I find 

 an absolute agreement between two species in all the structural 

 characters I incline to consider them as belonging to the same 

 species, whatever the difference may be in marking or color, until 

 I prove to my own satisfaction that the range of variation in 

 marking departs from what is usual or possible in the genus. I 

 am very much more conservative in the matter of naming va- 

 rieties than many of our Lepidopterists of the present day, and 

 I may be wrong and they right. I cannot see the use of bur- 

 dening our lists with a lot of really unmeaning names, like, for 

 instance, all those names applied by Prof. French to the species 

 of Leptarctia, and I may cite others that are as poorly based. I 

 think, however, you have my views on the subject at sufficient 



length.

NOTES ON TYPES OF NORTH AMERICAN GEOMETRINA

A specimen in the Museum has a label in Dr. Packard's hand- 

 writing, Tephrina modestaria Pack. It is the same as T. argil- 

 iacearia Pack. I do not know that it was ever described. 



Mr. J. Alston Moffat, Curator of the Entomological Soci< t\ 

 of Ontario, who has examined for me the material of tin- PTrlun 

 collection, writes me that Numcria inccptaria YVlk. 1667, is this 

 same species, and in that case Walker's name has prinriu . 1 am 

 much indebted to Mr. Moffat for his determinations, and take this 

 occasion to express my thanks to him.
