IA'1 FIFTH EtEPORI OF mi. ENTOMOLOGICAL COMMISSION. 
The reasons why I regard this species as pertaining to the genus 
Aphropkora^ to which Say had assigned it, instead of the genera iu 
which it bas recently been placed, will be found stated under a kindred 
species In iay Third Report, No. 98. (Fitch.) 
What 1 suppose to be this insect I8 also very common on the pitch 
pine at Brunswick, Me. The pupa* are common late in July, but early 
in August the insects acquire their wi.

Ajihrojihora saraioytusi* Fitch. 
A similar insect with the same habits with the preceding, hut differing from it in 
baying (he punctures uneolored, and the head above with its anterior and posterior 
margins parallel. It is of a lighter color than the foregoing, being pale tawny-yellow 
varied with white. It is much more attached to the pitch-pine than to the white 
pine, and is very common upon the small trees of that kind growing upon the sandy 
plains of Saratoga County. ^ Fitch.)

Iletinia comstockiana Feruald. 
Boring into the twigs and small branches of the pitch-pine (Pinus rigida), causing 
an exudation of resin: yellow-brown larvae about 10 mm (.39 inch) long, transforming 
within the burrow, and giving forth small brown and gray moths. (Comstock. 
Au examination of the pitch-pines iu the vicinity of Ithaca, X. Y.. in 
the early part of the past summer,* revealed the fact that they were 
infested to a considerable extent by a heretofore uudescribed pest. 
Upon the smallest twigs and limbs and upon the terminal shoots of the 
trees were observed exuding at intervals masses of pitch, mixed with 
the excremental pellets of some larva. In most cases there were two 
distinct layers of the resin to be seen, the lower dry, hard, whitish, 
weather-beaten, having evidently been exposed during the winter, while 
the upper mass was fresh, softer, and of a hoary, bluish color on the 
surface, yellowish beneath, having the appearance of a comparatively 
recent exudation. Tnese resinous lumps, when occurring upon twigs 
or limbs, were, in the great majority of cases, upon the upper side, and 
were seldom found upon a larger limb than the one represented in the 
cut. 
A longitudinal section through one of these lumps showed a channel 
of greater or less size leading directly to the heart of the twig, and 
extending along toward its base for a distance of from 25 to 50 mm (1 to 
2 inches). In this burrow was found a rather stout, yellowish-brown 
larva, apparently nearly full grown, and measuring about 10 mm (.29 
inch in length. In other burrows the short, stout, brown pup* were 
found. They were quite active, and retreated to the bottom of the
