34. Lophyrus sp. 
On spruce September 11, 1887 ; a Lophyrus larva, with the head red- 
dish ; the body pale yellow, with the dark stripes uuusually distinct, 
especially a broad lateral dark brown stripe. An allied species is rep- 
resented ou PL vni, figs. 5, 5a. 
35. Lyda sp. 
(Plate X; fig. 7, la.) 
Order Hymenoptera ; family TenthredinidjE. 
A Lyda larva, new to ine, occurred ou the spruce July 1 to 7, 1886, at 
Brunswick, Me., making a mass of castings 1J inches in diameter, near 
the end of the branch, and forming galleries among the castings. The 
worms, on being placed in another branch, soon spun a large web, 
within which they glided about. They 
were kept for a number of weeks in 
confinement under the best possible 
conditions, but finally died. 
Larva. — Body rather long and slender, but 
moderately thick ; head and prothorax of the 
same thickness. Head black, prothoracic seg- 
ment jet black, with adorsalshield and a lateral 
rounded boss. Thoracic feet black. Su banal 
abdominal legs 3-jointed, black, basal joint 
paler at base. Body dull livid olive green, 
stained with faint purplish. A dorsal and a 
vertical median dark diffuse line. Body much 
wrinkled, with purplish warts ou the wrinkles. 
A distinct lateral raised line. Supraanal plate 
large, with a V-shaped raised area and lateral 
ridges, the sunken spaces between the raised 
ridges dark. Length, 23 mm . 
36. Lyda sp. 
This species appears to be different 
from the preceding species ; it occurred 
on the spruce at Brunswick, Me., Sep- 
tember 18, 1884. 
Larva. — Body of the usual shape. Head dark, 
pitchy-brown ; the prothoracic shield small and 
of the same color as the head. Body pale, flesh-
