THE NANTUCKET PINE MOTH. 745 



band composed of the leadeu aud white scales. Fringes light brown above and be- 

 neath ; forewings 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 irrorations on the costa 

 and outwardly ; fringes long at the anal angle, somewhat lighter and with a darker 

 line near the base. Expanse of female, 18-20™'" ; male 18-20""™. Habitat. — Ithaca, 

 N. Y. Described from two males aud three females. 



I have ijrovisionally referred this species to the genus Betinia, for 

 although it agrees with the definition of the genus as given by Heine- 

 maim in other respects, the venation of the forewing differs in the 

 origin of veins four and five, which are not from the same point, but a 

 little remote from each otlier ; the distance between veins five aud 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 somewhat polished, under a high power cov- 

 ered with shallow pits. The piliferous warts are large aud 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, aud their dark circumference is very strongly 

 marked. 



Pupa. — Length, T"""'. 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 iilaments, having their origins close together and 

 spreading. (Comstock.) 



Two species of Ichneumonid parasites have been bred from the larvse, 

 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. Com stock's Eeport.

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 larvie which 

 transform wiihin grayish cocoons, either in their burrows or fastened to the twigs 

 and become small copper-colored moths, with wing expanse of 12'"'" (.47 inch).
