10 Winter Insects of Eastern New York. [May, 
als that come forth earliest, but I am unable to detect any marks 
by which they may be characterized as specifically dist) rom 
those which appear at a later day. 
7. Tricuocera prumauis. The Mid-winter Trichocer 
Brownish-black; wings and legs pallid at their bases; poisers 
blackish, their pedicels whitish. 
Length of the male 0.18, of the female 0.25, the wings expand- 
ing twice these measurements. 
Thorax with an obscure grayish reflection. Abdomen in the 
males cylindrical, slightly narrower towards the tip, in the fe- 
males elongated-oval, and pointed at the tip; each segment with 
a strongly impressed transverse line in its middle, and the posterior 
margin elevated into a slight ridge. Ovipositor fulvous, some- 
times tinged with blackish. Wéngs hyaline, faintly tinged with 
dusky; inner margins ciliated with quite short hairs; nervures 
blackish. Legs very long, slender, and fragile, blackish; femurs 
brown, gradually paler towards their bases. 
Common in forests in the winter season, coming out in warm 
days, flying in the sunshine, and alighting upon the snow, its 
wings reposing horizontally upon its back when at rest. Even 
when the temperature is below the freezing point, and the cold 
so severe as to confine every other insect within itscoverts, this may 
be met with abroad upon the wing. It isa plain, unadorned 
species, closely allied in its characters and habits to the European 
T. hyemalis, but in a number of impaled specimens before me, 1 
can detect no stripes or bands upon the thorax; whilst the very 
obvious character of the legs and wings being pallid at their ba- 
ses, Ido not find mentioned as pertaining to that species. 
8. Popura Nrvicona. “ The Snow-flea.” 
Black or blue-black; legs and tail dull brown. 
Length 0.08. 
Body black, covered with a glancous blue-black powder but 
slightly adherent, and sparingly clothed with minute hairs; form 
cylindrical, somewhat broader towards the tail. Antenne short 
and thick, longer than the head. Legs above blackish, beneath dull 
brown and much paler than the body. Tail of the same color 
with the venter, shortish, glabrous on its inner or anterior sur- 
face, with minute hairs on the opposite side; its fork -Lrownish. 
Though found in the same situations as the European P. niva- 
lis, ours is a much darker colored species. Say’s P. bicolor isa 
Jarger insect than the one under consideration, and differs also in 
size and in the color of the tail or spring. From the habits of the 
present species, we should infer that it might be abundant in all 
the snow clad regions of the northern parts of this continent; it
