AFFECTING THE LEAVES. 
7. The fir-tree baw-fly. 
Lophyrus abietis Harris. 
Order Hymenoptera ; family Tenthredinid.e. 
This pest of the fir which also infests pines has been described on 
page 757. 
The specimens I found of this species, the females of which I raised 
from the larva and submitted to Mr. E. Norton for identification, had 
larvae, of which the following description is taken from my notes. Much 
like that ou the cedar and juniper, but darker green, with a black head 
and thoracic feet. Median dorsal stripe pale instead of dusky, and be- 
sides a pale subdorsal stripe, with a whitish green lateral firm stripe. 
Beneath paler green than above. Of the same size. It spun a light 
silk cocoon August 23. The imago was found dead in the breeding box 
September 14, 1881, and must have left the cocoon during the first week 
in September. The antennae are black, serrated. Body dull horn- 
yellow; abdomen a little paler, more amber colored; legs concolorous 
with the body. Wings smoky, with black veins. Length 7 mrn . Cocoon 
regularly oval-cylindrical ; of a pale silken brown ; length 8 rara . 
8. The tussock mo i h. 
Orgyia leucostigma Abbot-Smith. 
Order Lepidoptera ; family Bombycid.£. 
Feeding on the leaves of the fir in July and August in Maine, a hairy caterpillar 
with two black pencils ot hairs in front, one median, one behind; four medio-dorsal 
short thick yellow tufts, succeeded by three dorsal coral-red tubercles, on the back.

or into the skin prove very annoying. I once crushed one of these
