800 FIFTH KEPORT OF THE ENTOMOLOGICAL COMMISSION. 
were detected, bat I found the larva September l'7, 1882, at Providence, 
R. I. 
I. ana. — Deep orange in color, with tin- •• breast-bone "' retractile. The lateral swol- 
len region of the body la well marked, convex, and tin- tegmenta are short, quite 
convex. 
ale described from life.— Antenna- 14-jointed, about half as long as the body, 
brown, with aparae, irregular rertioila of gray hairs, the ten terminal joints twice as 
long as broad, and pedicellate. Clypena and epicraninm testae-cons brown, the cly- 
peus (hypoatoma I having a few long gray hairs curviugover and downward. Palpi 
OOnoolorona with the ends of the antenna*. 
Thorax shining black, with four lines of white hairs, as in C. pini DeGeer ; the sides 
including the prothorax, reddish ; scutelluin reddish-brown, while the trochanters 
are much darker, the first pair being nearly black, the two posterior pairs reddish- 
brown. Legs brown, paler beneath, with gray hairs, the tarsal joints darker at the 
articulations, covered with fine silvery hairs. 
Wings rather short and broad, with scarcely any pubescence ; friDge long, veins 
dark brown ; the subcostal (first longitudinal) vein terminates at the middle of the 
wing (in C.salicis it terminates much beyond this point) ; the median vein terminates 
at or perhaps a little below the apex ; it curves around rapidly. following the curve of 
the margin ; cross-vein very minute, very oblique, almost obsolete, situated a little 
before the middle of the first longitudinal vein ; third longitudinal vein straight, but 
turning down to the iuner margin at nearly a right angle. The venule which, in 
continuation of the main vein, is bent upward at its origin, thence goes straight to 
the outer edge, inclosing a triangular space. The halteres are pale rlesh-colored. 
Abdomen blood-red, with slight sparse hairs. The segments on the terminal half 
of the abdomen are edged with black, aud the tip of the abdomen is blackish, while 
the genital armature is flesh-colored. Length, .10 inch. 
This species differs decidedly from Dij)losis pini Loew, 9 , in that the 
basal joints of the antenna are not yellow, but pale brown. The cly- 
peus (hypostoina) 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 description of D. pini, but are sparingly so. 
The cross-vein is difficult to find, and then is only seen in certain posi- 
tions. It is smaller, being only a tenth of an inch long. 
In its habits it seems to differ from OsteiiSnckeii'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 pinii)ioj)is living on 
the Jersey or scrub pine (Pinus inops), which does not extend so far 
north as New England, particularly Maine.
