described, and most of these have been made known in quite 
recent years. 
When Walker catalogued the Eupithecie of the world in 
1862, he only credited North America with five species. In 
Packard’s Monograph published in 1876, only twelve species 
were recognized. But the labors of Dr. Hulst have vastly in- 
creased our lists in this genus and the allied genera, so that in - 
Dyar’s Catalogue we find enumerated no fewer than 55 species of 
Eupithecta, four of Gymnocelis and eight of Hucymatoge—67 pugs 
in all; and, yet, even this number falls considerably short of the 
number of apparently distinctspecies which are represented at the 
present moment in my own collection. 
The species sent by Mr. Young all belong to the typical 
genus Hupithecia, and I have determined them as follows : 
1. Eupithecta geminata, Pack., (which is probably, but not 
certainly, the Hupzthecia coagulata ot Guenee and is cer-_ 
tainly mot the &. abstnthiata, Linneus, under which ~ 
name it appears in all our recent lists, 
2. Eupithecia ornata, Hulst, 
Be 5 latipennis, Hulst, 
4. 45 palpata, Packard, 
5 “5 albicapitata, Pack. (a very rare species, so far as 
I know, this being the first specimen to come under my 
notice), 
and three species which are apparently without names. Two 
of these require further study of more abundant material before 
they can be safely characterized ; but the third I propose to 
describe now and to name after my kind correspondent from 
whom I have received the very beautiful and absolutely perfect 
specimen which I shall designate the type of the species. 
I may add here that I shall be greatly obliged, and I am sure 
science will be benefited, if Canadian entomologists will endeavor 
to collect good series of Hupithecie during the coming season, in 
order that the species native to the Dominion may be correctly 
determined, and those that prove new, furnished with suitable 
names.
