INSECTS INJURIOUS TO THE PINE. 255 
Abdomen blood-red, with slight sparse hairs. The segments on the terminal half 
of the abdomen are edged with black, and the tip of the abdomen is blackish, while 
the genital armature is flesh-colored. Length, .10 inch. 
This species differs decidedly from Diplosis pini Loew, 9, in that the 
basal joints of the antenne are not yellow, but pale brown. The cly- 
peus (hypostoma) is reddish-brown, not reddish-yellow. The abdomen 
is blood-red, and the hairs are too few to give a silvery reflection ; the 
legs do not seem whiter beneath than above; the wings are not densely 
pubescent as in Loew’s descriptionof D. pini, but are sparingly so. The 
cross-vein is difficult to find, and then is only seen in certain positions. 
It is smaller, being only a tenth of an inch long. . 
In its habits it seems to differ from Osten-Sacken’s Diplosis pini-inopis 
in that the apparently similar pale, oval, resinous, pitchy cocoons are 
placed on the buds of the pine-needles, which were somewhat deformed, 
and could thus be easily distinguished from others not affected; as well 
as by the resinous pitchy exudation covering them. (This was observed 
May 20.) The food-plant is also different, Diplosis pini-inopis living on 
the Jersey or scrub pine (Pinus inops), which does not extend so far 
north as New England, particularly Maine. 
86. THE PINE SAWFLY (Lophyrus sp.). 
Order HYMENOPTERA; family TENTHREDINIDA. 
Body pale yellowish-green, segments with numerous fine transverse wrinkles; head 
black ; thoracic legs black. Observed August 17 on pitch pine at Brunswick, Me. 
87. THE PHILADELPHIA CHRYSOMELA. 
Chrysomela philadelphica Linnzeus. 
Order COLEOPTERA; family CHRYSOMELID#®. 
Feeding upon the leaves from May till September, a very convex broad-oval beetle 
about 0.30 long, of a dark bottle-green color with white wing-covers sometimes tinged 
with yellow and having on them numerous spots and dots of dark green with a black 
line on the suture widened anteriorly and a second line parallel with this on each side, 
the antenne and legsrusty red. This is also common upon willows, with other species 
closely similar to it. (Fitch.) 
88. THE PINE CHRYSOMELA. 
Glyptoscelis hirtus Olivier. 
Order COLEOPTERA; family CHRYSOMELID.E. 
Feeding on the leaves in May and June, a thick cylindrical beetle resembling the 
Cloaked Chrysomela, No. 27, but with the pubescence much thinner than in that and 
the other American species of this genus. Its color is brassy, more brilliant on the 
under side and tinged with coppery. The male is usually 0.28 and the female 0.35 
long. (Fitch.) 
89. THE SARATOGA LEAF-HOPPER. 
Aphrophora saratogensis Fh. var. 
. Order HEMIPTERA; family CERCOPID®. 
The larve form masses of froth on the leaves of the white pine in June, acjuiring 
wings the last of July and in August in Maine. Common, (Named by Mr. Uhler.)
