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 

 IN EUROPEAN COLLECTIONS.— II.

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

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

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



Mr. J. Alston Moffat, Curator of the Entomological Society 

 of Ontario, who has examined for me the material of the D' Urban 

 collection, writes me that Numeria inceptaria Wlk, 1667, is this 

 same species, and in that case Walker's name has priority. I am 

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

 occasion to express my thanks to him. 



Thamnonoma tripundaria Pack, is put by Mr. Warren as a
