192 INSECTS INJURIOUS TO FOREST AND SHADE TREES. : 
white and leaden-hued scales extend, more or less irregularly, across 
the wing at nearly right angles with the costa, and having something 
of a wavy appearance in some specimens, with some indication of a 
basal patch, a central and subterminal band composed of the leaden 
and white seales. Fringes light brown above and beneath; 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 irrora- 
tions on the costa and outwardly; fringes long at the anal angle, some- 
what lighter and with a darker line near the base. 
Expanse.—Female, 18-20" ; male, 18-20™". Habitat.—Ithaca, N. Y. 
Described from two males and three females. 
I have provisionally referred this species to the genus Retinia, for 
although it agrees with the definition of the genus as given by Heine- 
mann in other respects, the venation of the fore wing 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"™, cylindrical, tapering very 
slightly at the ends. General color yellowish; head, thoracic plate, and 
piliferous spots brown and highly polished ; anal plate dusky and some- 
what polished, under a high power covered 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 tour 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 larve differ in being darker colored. The head and tho- 
racie 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™™. 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, bearing 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 larve, 
both furnished with long oviporitors to pierce the resinous mass. One 
is a species of Agathis; the other is Hphialtes comstockii Cresson de- 
scribed in Mr..Comstock’s Report.
