7. THE FIR-TREE SAW-FLY. 
Lophyrus abietis Harris. 
Order HYMENOPTERA; family TENTHREDINID®&. 
This pest of the fir which also infests pines has been described on 
page 197. 
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 
larvee, of which the following description is taken from my notes. 
Much like that on the cedar and juniper, but darker green, with a black 
head and thoracic feet. Median dorsal stripe pale instead of dusky, 
and beside 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 antenne 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™™. Cocoon regularly oval-eylindrical; of a pale silken brown ; 
length 8™™,
