PINE BUTTERFLIES. 767 
secondaries beneath. None of them have so much red ; many none at all, and not 
one shows any trace of the streak near the inner margin. As I have not access to the 
description of the female by Felder, I forward a series to the editor of Papilio. Should 
he find them to differ largely from Felder's description, I would suggest the name of 
11 suffusa" for this variety, as it is very constant. 
Description of larva.— General color green. Head green, covered with small white 
points ; mouth-parts dusky; low down on each side a curved row of four black dots. 
Body clear green, tinged with purplish, and with two lateral yellowish-white 
stripes. In the dorsal green stripe the purplish tint shows itself as a faint dorsal 
line, and on the edge of the upper lateral line, leaving clear green between. The 
upper edge of the upper lateral stripe is clean cut ; the lo wer edge more diffuse, shading 
into green, and that color being tinged with purplish along the upper edge of the 
lower lateral stripe, which is somewhat broader than the upper one and better 
defined. Anal segment somewhat horny, narrow, and slightly notched at the tij>. 
Venter dusky green. Prolegs black. Abdominal legs dusky green. Length, 1 inch. 
Note. — I have in this paper assumed that all the damage done to the yellow pines 
was caused by P. menapia. It is only fair to state that on the edge of the timber, 
north of Spokane Falls some 4 or 5 miles, I came across a large Bombycid larva 
which denudes the foliage in a similar manner. From one small pine, not more than 
12 feet high, I took some thirty specimens and might have taken a hundred. These 
were in a district where P. menapia was uncommon. We did not have time to make 
any extended search on other trees, but it may be possible that a portion of the dam- 
age has been done by these insects. It could not have been common, however, in the 
affected district, as a close watch on the habit of menapia did not reveal its presence. 
I have a number of cocoons of this insect, from which I hope to raise the imago, 
which is probably allied to the genus Parorgyia. If I succeed, I will put the obser- 
vations on record. — [San Fransisco, August 9, 1882. 
87. The pine thecla. 
Thecla niphon (Hiibner). 
Order Lepidoptera ; family Lyc^nid^:. 
Feeding upon the leaves in summer, a flattened oval worm, .75 long when full- 
grown, of the same deep green color as the leaves, with a light yellow stripe along 
the middle of its back and a white one on each side, and a brown head ; changing 
to a short thick grayish pupa with two rows of small blackish spots, and outside of 
these a row of more conspicuous rust-red ones, which is attached by its tail and by a 
thread around its middle in form of a loop ; giving out a smallish butterfly which 
comes abroad in April and the fore part of May; 1 to 1.15 in width across its 
wings, which are of a dusty rust color and without spots above, paler grayish be- 
neath, the fore ones with a dislocated black band beyond the middle, edged on its 
hind side with snow white, and beyond this a row of black crescents, each with a 
white spot in its concavity, and the hind wings similarly but more complexly varie- 
gated. (Fitch.) 
Boisduval says : 
This insect lives in Georgia and Florida, on several species of pine, and is very 
rare and seldom seen in collections. 
It is, however, a common species in the State of New York, in all 
our forests where pine trees abound, coming oat with the first warm 
days of spring, before collectors are much abroad in search of insects, 
and continuing but a short time. (Fitch.)
