EUPITHECIA VOUNGATA. 
A GEOMETRID MOTH FROM OTTAWA NEW TO SCIENCE. 
By Geo. W. Tay.Lor, Wellington, B.C. 
During the past three years I have devoted nearly all my 
leisure to the study of North American Geometridez, and I have 
been very greatly helped by a number of entomologists who have 
allowed me to examine the specimens in their cabinets and who 
have, moreover, liberally added. to my own collection. In this 
way I have made the acquaintance of a large majority of the 
American species so far made known to science. There are, how- 
ever, many forms that are still undescribed, and, though these 
‘‘ new species”’ are naturally more numerous in the West and 
South than in the Eastern Provinces of Canada or the older States 
in the Union, where entomological researches have been carried 
on for a century or more, there are still some—perhaps more than 
we suppose—of these nondescripts to be found evenin Ontario. 
Indeed, the subject of the present paper was captured close 
to Ottawa itself, which, when we consider the many eminent 
entomolegists who have worked there so enthusiastically during 
the last twenty-five years and the activity of the members of the 
_Field-Naturalists’ Club generally, might be looked upon as the 
least likely place in all Canada to produce novelties. The captor 
of the species I am about to describe,was Mr. C. H. Young. Mr. 
Young has sent me for study, from time to ‘time, specimens of 
nearly all the Geometrid# he has taken at Ottawa, Meach Lake 
and the Mer Bleue ; and, after seeing these specimens, many of 
which he has generously allowed me to retain in my own cabinet, 
I am compelled to say, as so many others have said, that more 
beautifully prepared specimens could not be imagined. 
Mr. Young sent me not long ago a number of smail 
Geometridze from Ottawa for determination. Among these I . 
found no fewer than eight species of the interesting genus 
Eupithecia, Of these little moths, ‘‘Pugs,”’ as we used to call them 
in England, there must be over one hundred species native to 
North America; but only about one-half that number have been
