828 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



ually narrowed behind, and the apex is rectilinearly attenuated from the 

 suture, while in M. appendiculata the inner outline of the tip is concave^ 

 though not so much so as in M. atropurpurea. The tip of the abdomen, 

 as in the others of this group, is slightly emarginate, with the angles 

 acute. 



Eather long and slender larvfe, with the segment next behind the 

 head much narrower than in Chrysohothris, occurred in abundance 

 under the bark of a dead spruce at Brunswick, August 27. They were 

 nearly fully grown. The larvse of either this or an allied species also 

 occurred under the bark of a spruce near the Glen House, near Gor- 

 ham, K H., July 22. 



9. Melanophila sp. 



(PI. XVII, Fig. 4; XXII, Fig. 1.) 



Head of moderate size. Autennse very abort, 3-jointed; second joint much shorter 

 than long; third very short and blunt, much more so than the unknown (spruce) 

 genus, or in Chrysohothris or Dicerca. Labrum much as in the other genera men- 

 tioned ; rather narrow, and moderately full on the front edge. Maxillary lobe well 

 developed, with a spine pointing inwards ; maxillary palpi with the second joint as 

 long as the first. Labium slightly indented in the middle, but so slightly so that it 

 can not be represented in a figure. Mandibles tridentate. Prothorax unusually 

 short, about half as long as broad, the sides well rounded ; the roughened chitinous 

 disk is very small, not much over one-third as wide as the entire segment ; it is round, 

 slightly longer than broad, inclosing a narrow inverted V, which extends the whole 

 length of the disk. On the under side the disk is subtrapezoidal, widening at base, 

 the sides hollowed out, and narrower than long. The meso and metathoracic seg- 

 ments unusually long, and of the same size, being about two-thirds as wide as the 

 prothorax. First abdominal a little shorter than the second abdominal segment ; 

 segments 2 and 8 of the same size, and very full and rounded on the sides. The 

 ninth segment somewhat narrower than the eighth, and the tenth is oue-thira to 

 one-half as wide as the ninth. Length, 12 to 19">™ ; in one 12"^^ long the prothorax 

 is 1"™ long and 2.5™'" broad; the eighth abdominal segment about 1.5'"™ broad. 



This is evidently a species of Melanophila, and differs from the other 

 genera mentioned in the short and wide prothoracic segment, in the 

 very small disk inclosing a narrow V, and being trapezoidal beneath, 

 while the abdominal segments are very convex, and broad in propor- 

 tion to the prothorax. It may also be identified by the very slightly 

 bilobed labium and well-developed maxillae. 



This is No. 2 " unknown Buprestid larva," on the spruce, p. 228 of 

 Bulletin 7, and No. 4, p. 241, on the hemlock. 



10. Flat-headed spruce borer. 



Melanophila sp. 



In the form and size of the head, prothorax, and body, including the 

 tenth segment, closely like Dicerca, but the sculpturing is decidedly 

 different. The description of the proportions of the prothorax and suc- 

 ceeding segments of the body in Dicerca will apply to this species. The 

 prothoracic disk is, however, very different ; it is transversely rounded- 

 oval, very regular in shape, and smaller than the disk of Dicerca ; it is
