THE NANTUCKET PINE MOTH. 745 
baud composed of the leaden and white scales. Fringes light brown above and be- 
neath ; fore wings light brown beneath ; ferruginous apically, with the white spots 
of the costa well indicated. Hind wings above and beneath grayish brown, with a 
tinge of ferruginous in some specimens and with darker irroratious on the costa 
and outwardly ; fringes long at the anal angle, somewhat lighter and with a darker 
line near the base. Expause of female, 18-20™° ; male 18-20 mm . Habitat. — Ithaca, 
N. Y. Described from two males and three females. 
I have provisionally referred this species to the genus Retima, for 
although it agrees with the definition of the genus as given by Heiue- 
mann in other respects, the venation of the {brewing differs in the 
origin of veins four and five, which are not from the same point, but a 
little remote from each other ; the distance between veins five and six 
at their origin is about twice the distance between veins four and five. 
The moth has also been taken by Mr. Otto Lugger at Baltimore, Md. 
Larva.— Length, when full-grown, 12 mm , cylindrical, tapering very slightly at the 
ends. General color yellowish ; head, thoracic plate, and piliferous spots brown and 
highly polished ; anal plate dusky and somewhat polished, under a high power cov- 
ered with shallow pits. The piliferous warts are large and quite prominent, each 
bearing a stiff hair. Their arrangement is normal. The anal shield is furnished 
with two transverse rows of four hairs each ; the posterior row, from a dorsal view, 
appearing to fringe the end of the body. The stigmata are light colored, surrounded 
by a dark-brown chitinous ring. Thoracic legs and bases of prolegs brownish. 
The young larvae differ in being darker colored. The head and thoracic shield are 
lighter; the piliferous spots are hardly discernible ; the stigmata are much larger in 
proportion to the size of the larva, and their dark circumference is very strongly 
marked. 
Pupa. — Length, 7 mm . General color dark shining brown, darkest on dorsum of 
thorax and head ; wing-sheaths broad, extending to third abdominal segment. The 
posterior border of each abdominal segment dorsally elevated to a spiny ridge, bear- 
ing many strong backward-directed spines. Anal segment somewhat truncate, with 
a number of slender hooked filaments. Eyes very black and prominent. Between the 
eyes two pairs of the hooked filaments, having their origins close together and 
spreading. (Comstock.) 
Two species of Ichneumonid parasites have been bred from the larvae, 
both furnished with long ovipositors to pierce the resinous mass.. One 
is a species of Agathis ; the other is Ephialtes comstockii Cresson, de- 
scribed in Mr. Comstock's Report.

(Plate vn.) 
Infesting the new growth of the pitch-pine (P. rigida) and Pinus inops (and perhaps 
of other species), spinning a delicate web around the terminal bud, and mining both 
the twigs and the bases of the leaves ; one or several small yellowish larvae' which 
transform within grayish cocoons, either in their burrows or fastened to the twigs 
and become small copper-colored moths, with wing expanse of 12 mm (.47 inch).
