856 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION 
I found only one tree next to the house thus affected by this worm. 
It is probable that in a dense spruce growth the trees would be less 
exposed to the attacks of what may prove a 
serious enemy of shade spruces. The obvious 
remedy is, to burn the affected coues and mass 
of castings late in summer.

(enlarged, original). 
Larva. — Of the usual Phycid form; the head awl prothoracic shield deep amber 
brown ; the body reddish carneous or amber-brown, with a livid hue; a faint, dark, 
dorsal, and a broader, subdorsal line ; piliferous warts distinct : each segment divided 
into a longer anterior and shorter, narrower, posterior section, bearing two dorsal 
piliferous warts, besides a lateral one. Length 16 mm . 
Pupa. — Of the usual Phycid appearance; rather slender, the abdominal tip blunt, 
with six long slender up-curved bristles. Length 9 mm . 
Moth. — 1 male. Fore wings long and narrow, stone-gray, with no reddish or brown- 
ish tints. Head, palpi, and body dark gray with white scales intermixed. Fore- 
wings dark and light gray; a broad basal light pitch; before the middle of the 
wing a white zigzag line composed of a costal and median scallop. A square whitish 
distal patch, and half way between it and the outer margin is a narrow white zigzag 
line inclosed on each side by a dark border, the line being deeply angulated three 
times. Edge of the wing next to the base of the fringe deep black, interrupted by 
narrow pale gray spots. Fringe dusky, with line white scales. Legs banded with 
black and gray. Hind wings pale gray. Expanse of wings 22 mm ; length of body 
10mm, (Identified by Prof. C. H. Fernald.) 
In "A note on Dioryctria decuriella and its allies," in the Entomol- 
ogists' Monthly Magazine for March, 1888, E. L. Ragonot remarks : 
u The North American Pinipestis reniculella Grote and P. abietivorella 
Grote I consider only dark forms of decuriella Hb., and, of course, the 
generic name of Pinipestis Grote is simply synonymous with Dioryctria 
Z." He states that D. decuriella Hiibn. (abietella S. Y.), feeds both on 
firs and pines, and that the larva " lives in the cones, young shoots, 
and decayed wood of the conifera?." 
42. Thk pine nephofteryx. 
Pinipestis Zimmermanni Grote. 
This is said by Mr. Zimmermaun to be destructive to young spruces 
in New York. (Can. Ent., xn, p. 59.)
