828 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 
iiiilly narrowed behind, and the apex is rectilinearly attenuated from the 
suture, while in M. appindhulata 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. 
Rather long and slender larvae, with the segment next behind the 
head much narrower than in Chrysobothris, occurred in abundance 
under the bark of a dead spruce at Brunswick, August 27. They were 
nearly fully grown. The larvre of either this or an allied species also 
occurred under the bark of a spruce near the Glen House, near Gor- 
ham, N. H., July 22. 
9. Melanophila sp. 
(PI. xvn, Fig. 4; xxn, Fig. 1.) 
Head of moderate size. Antenna; very short, 3-jointed; second joint much shorter 
than long; third very short and blunt, much more so than the unknown (spruce) 
genus, or in Chrysobothris 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 subtrapezoidai, 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 one-third to 
one-half as wide as the ninth. Length, 12 to 19 mm ; in one 12 mm long the prothorax 
is l mm long and 2.5 ram broad; the eighth abdominal segment about 1.5 mm 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 maxilla?. 
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, aud smaller than the disk of Dicerca; it is
