appearing as three oblique branch veins; stigma usually elongated and 
much pointed at the tip. Hind wings with one, more or less dis¬ 
tinct, branch vein. 
Legs in the winged individuals, rather short, the posterior pair, 
usually not longer than the middle pair; all rather short; in the apti- 
rous individual very short. Body of the winged individual regularly 
oval; of the apterous nearly circular and'; convex. No honey-tubes. 
Usually more or less covered with a cottony secretion. 
The' species so far as observed appear to be more particularly confi- 
ved to to coniferous trees. 
Chermes pinifolke, Fitch. 
This genus as understood by Dr. Fitch, appears to include those 
species in which the female is oviparous, but does not extrude her eggs; 
but clinging to the leaf, the abdomen swells and finally she perishes, 
leaving themass of eggs adhering to the leaf, thus showing a close 
relation to the Coccidae, or bark-lice. But on the other hand, the win¬ 
ged individuals possess four wings instead of two, which character 
places them among the Aphides. The other characteristics will be found 
in the following specific characters of this species. The winged indi¬ 
viduals black, 0.08 inch in length to the tip of the abdomen, 0.12 
inch to* the tips of the wings; abdomen, dusky-red and slightly covered 
with down; the wings, dusky and grayish; the rib-vem of the fore 
win^s runs straight to the outer margin forward of the tip, and gives 
off from its middle, on the outer side, a very oblique branch which 
runs to the outer margin, its tip producing a slight, angular projection 
of the margin; on the inner side of the rib-vein there are three bran¬ 
ches or discoidal veins, all simple, the third running to the tip of the 
wing. The hind wings have an angular point on the outer or front 
margin; the rib-vein sending off one branch; antennae short, thread¬ 
like, and four or five jointed. 
Found during the summer, stationary upon pme leaves. 
Chermes laricifoli^e. Fitch. The Larch Chermes. 
Similar to the preceding species; but found on the leaves of the 
American larch or tamarack. Shining black, 0.10 of an inch long, 
abdomen dark green; legs pale or whitish; wings nearly hyaline, with 
pale brown veins; the large stigma opaque and pale green.
