but the black is mostly in coarse streaks containing several small tufts. Tbe costa 

 beyond tbe middle is blackish, with three small white spots at nearly equal dis- 

 tances apart. The fringes of the fore wings, the upper side of the hind wings and 

 abdomen are darker gray with a silky lustre. The under side of tbe hind wings 

 is lighter, witb darker cross-streaks or reticulations, whicb are much brighter to- 

 wards the apes. Tbe under side of the fore wings is dark gray, except along the 

 costal border, where the markings of the upper side are dimly reproduced. The 

 legs are brown on the outside, but pale yellowish within and on the end of the 

 joints. This seems to be a very variable species, and at first sight one might tbink 

 that there were more than one species. 



One variety has the top of the head yellowish, and the oblique band and outer 

 part of the wing dull whitish and slightly touched with yellowish. Another va- 

 riety is quite dark, and has a broad bright ochre yellow band through the middle 

 of the fore wing, from the base to the apex. 



A third variety, in very poor condition and bred on white spruce in Ashland, Me., 

 has the head white and the basal part of the fore wings white with only slight traces 

 of the black tufts and markings. Expanse of wings, 14 mm (Fernald). 



THE FIR TORTRIX. 



(Toririx packardiana, n. sp., Fernald.) 



This moth was bred from the fir on Peaks Island, Casco Bay, Maine, 

 and sent to Professor Fernald, who regarded it as new and sent ns the 

 following description : • 



Head whitish: palpi and thorax ashy gray; fore wings with a whitish ground 

 color, and marked with black, which is more or less overlaid with pale bluish or 

 whitish scales. The black basal patch has an obtuse angle pointing out on the mid- 

 dle of the wings. An oblique black band broken in the cell crosses the middle of the 

 wing. A black patch rests on the costa before the apex, marked with one or two 

 white costal spots; a similarly colored patch within and above the anal angle, and 

 still another on the outer border inclosing the apex, sends in a square projection to- 

 wards the end of the cell. All the black markings are overlaid more or less with 

 white scales, and the white portions of the wings are somewhat stained with gray. 

 The fringes are dark smoky brown. 



The hind wings and abdomen above are ashy gray. Fringes lighter. Under side 

 of the fore wings ashy gray, with tbe white costal marks reijroduced. Under side of 

 the hind wings whitish, irrorate with gray. Expanse of wings, 16-18 mm . 



Bred from Fir by Dr. A. S. Packard, for whom I name this species in 

 recognition of his extensive and valuable work on Xortli American in- 

 sects. 



THE RED SPRUCE BUD -WORM. 



(Gelechia obUquistrigeUa Chambers.) 



[Plate I. Fig. 2.] 



Associated with the preceding bud-worm occurred in abundance, both 

 on the terminal shoots of the spruce and tir, a little reddish cylindri- 

 cal caterpillar, about two-thirds as large as the larva of Teras variance, 

 and very active in its habits. It occurred as early as the 10th of June, 

 but it disappeared earlier than the caterpillar of Teras rariana, and 

 the moths, which were common, flying in spruce at and soon after the 

 middle of July, were not seen after the first week in August.
