800 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



were detected, but I fouud the laivne September 27, 1882, at Providence^ 

 E. I. 



Larva. — Deep orange in color, with the " breast-bone " retractile. The lateral swol- 

 len region of the body is well marked, convex, and the segments are short, quite 

 convex. 



Female described from life. — Antennae 14-jointed, about half as long as the body, 

 brown, with sparse, irregular verticils of gray hairs, the ten terminal joints twice as 

 long as broad, and pedicellate. Clypeus and epicranium testaceous brown, the cly- 

 peus (hypostoma) having a few long gray hairs curvingover and downward. Palpi 

 concolorous with the ends of the autennte. 



Thorax shining black,with four lines of white hairs, as in C. pini DeGeer ; the sides 

 including the prothorax, reddish ; scutellum reddish-brown, while the trochanters 

 are much darker, the lirst 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 ; fringe long, veins 

 dark brown ; the subcostaj (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 inner 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 flesh-colored. 



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 Biplosis pini Loew, 9 , in that the 

 basal joints of the antennse are not yellow, but pale brown. The cly- 

 peus (hypostoma) is reddish-brown, not reddish-yello% 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 (iifificult 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 Osten-^acken^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 couhl 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 {Pimis inops), which does not extend so far 

 north as New England, particularly Maine. 



129. The pine sawfly (Lophyrus sp.). 



Order Hymenopteka ; family Tenthredinid.e. 



Body pale yellowish-green, segments with numerous fine transverse wrinkles ; head 

 black ; thoracic legs black. Observed August 17 on pitch pine at Brunswick. Me.
