254 INSECTS INJURIOUS TO FOREST AND SHADE TREES. 
7. THE JUNIPER TWIG INCH-WORM. 
Drepanodes varus G. & R. 
This caterpillar, found on the tree-juniper (No. 4), also appears to 
live on the low-bush juniper, as we beat from a bush the Jast of August 
a beautiful green chrysalis which agrees closely with that of Drepanodes 
varus. This chrysalis is of the size and exact form represented in 
Fig. 95, is smooth bodied, pale pea-green, the exact color of a leaf of 
its food plant. The body is paler than the wings, with two pale sub- 
dorsal yellow stripes; the tip of the abdomen red. 
8. THE FIR-NEEDLE INCH-WORM. 
This caterpillar was found feeding on the juniper at Brunswick, Me., 
August 26-29, 1881.

oO 
Lachnus sp. 
Common on the juniper in Maine at the ends of the branches. 
INSECTS INJURIOUS TO THE LARCH OR TAMARACK (Larix amer- 
icana). 
1. The pine bark-beetle (Tomicus pini) is reported to mine the bark 
and outer surface of the sap wood of the tamarack the same that it does 
the pine. 
2. In July and August troops of white caterpillars with black dots 
and along their backs eight black tufts of hairs, the larve of the hickory 
tussock moth (Loptocampa carye), are sometimes found on this tree, 
nearly stripping the leaves from the limbs which they occupy. (Fiteh.) 
3. In Labrador [have found the larva of Arctia quenselii feeding upon 
the larch in July.

On the limbs in June and July, feeding on the leaves; a large flattened ash gray 
worm resting appressed to and closely resembling the bark ; forming an oblong flat- 
tened gray cocoon molded to the limb and resembling the bark in its color; the latter » 
part of July producing a thick-bodied moth with thin delicate wings, which are 
almost transparent in the males and 1.00 broad, in the females 1.50, and of a white 
color with faint wavy dusky bands. (Trans. 1855, p. 494. Fitch.)
