rondacks, from Pennsylvania, and from
Sudbury, Ont., Canada. At Jackrnan,
Me., it has been found in " open woods
and bogs ?? (Harvey, - Psyche, 1897,
p. 77). Mr. Scudder states that "it
frequents the dose branches of the
dwarf birch" in the White Mts, Some
of my specimens were obtained from
birch but most were found on or among
the various species of Vaccinium char-
acteristic of the mountain-tops, and on
Ascutney among dwarf cornel. It is
a somewhat sluggish insect, relying
chiefly for protection upon the similarity of its dark olive green coloring to that of the surrounding vegetation, though on warm days the males become fairly
active.
A NEW PARAS.4, WITH A PRELIMINARY TABLE OF THE SPECIES OF THE GENUS.
BY HARRISON G. DYAR, WASHINGTON, D. C.
The Eucleid genera Euclea and Parasa
are closely allied and indeed not well
separated. There 'is a stronger ten-
dency to the stalking of vein 10 of
primaries in Euclea, but some species
of Parasa show the same character.
Judging from the American larvae alone
there appear to be marked differences
in the early stages of the genera; but
the larva of P. /e/i;ĺ´/a a true Parasa, shows the more generalized Euclea
form, proving that our P. chloris is a
specialized offshoot, not a characteristic type for the genus.
Parasa is a widespread genus, being
represented in all the continents except Australia and Europe. The following
are its characters : -
Head partially sunken, untufted ; palpi
upturned, reaching half way to the ver-
tex, third joint small, evenly clothed.
Antennae of male pectinated on basal
half, the tip simple, the two regions
usually sharply marked off, occasionally grading into each other; simple in
female. Thorax smoothly haired, not
scaly. Abdomen extending moderately
beyond hind wings. Legs densely
hairy ; posterior tibiae with one pair of spurs. Fore wings with the costa
straight, rarely convex, outer and inner margins rounded ; two internal veins,
2 to 5 rather regularly spaced, 4 and 5
nearest at base ; 6 from cross-vein, 7 to g stalked, rarely 10 also shortly stalked, I I from cell, 12 from base ; discal vein often forked and open. Hind wings
with three internal veins, 2 to 5 regu-
larly spaced, upper half of cell retracted, 6 and 7 usually stalked, 8 anastornosing with cell toward base with more or less
distinct fine veinlets thrown off toward costa.
PARASA PRAsINA ft. sf.-Vertex of head
and thorax green, a few brown hairs at base of fore wings and a very narrow central

brown crest.
Fore wing green, a small basal
dark brown patch, widest on costa, a little angled on median vein and vein I, narrow- ing to nothing at inner margin. Outer
border very narrow, nearly confined to the fringe except between veins 5 to 8 where it widens inwardly; brown, shaded with sil- very, edged within by a dark brown line. A very small brown discal dot. Hind wings
creamy ocherous, the fringe brown and white. Below uniformly yellowish, fore wings a
little greenish, fringe brown tipped. Front of bead, palpi and pectus dark brown. Middle and hind legs yellowish. Vein 10 of fore wings from end of cell.
Expanse 2.5 mm.
Two 2 s without definite locality, but
from Mexico or Central America
(Heyde). U. S. Nat. Mus., type no.
4019. Nearest to P. inzifufa Druce.
The specimens mentioned in the Bio-
logia Cent. Am., (Lep. Het. 11, 441
(1898)), from Costa Rica with hind
wings pale cream color may be this
species.
In the following synoptic table of
Parasa I exclude certain species listed
by Kirby. Of these atfitis Wall. and
gemmans Feld. belong to Taeda accord-
ing to Karsch; ancilis Wall. is the type of Ectropa Wall., a genus very distinct
from Parasa as I learn from the struc-
tural details that Sir G. F. Hampson
has kindly sent me; ruh~iplaga Walk.
and zmirolor Moore belong to Idonauton
and Natada respectively (vide Hamp-
son's Moths of India). Besides these
I have excluded provisionally all species without any green marking on the thorax
as needing to be reexamined structurally. They are b&;/fata Walk., cruda Walk.,
cupeiplaga Walk., czIpreistriga Walk.,
humilk Mab., vetusta Walk., rzdticunda
Walk., rttdis Walk., palKda Moschl.,
chlorostigma Snell., and dentata Hamps.
The latter species differs in structural characters from Parasa as the male
antennae are serrate throughout. I
would propose that it be made the type
of a new genus, HAMPSQNELLA, with the
characters given in the "Moths of
India."
