INSECTS INJURIOUS TO THE PINE. 155 
in front, but as wide anteriorly as posteriorly. When the head is forei- 
bly pulled out it is found to be as long as broad; anterior one-fourth of 
head, deep mahogany red, becoming blackish on the. edge. Clypeus 
very short and broad, about four times as broad as long. Labrum 
rather wide, not much contracted at base, rounded in front, with very 
stout bristles on the margin. Mandibles gouge-like, the ends oblique, 
hollowed out, with the outer edge produced into a point. Antenne 
very minute, three-jointed, the second and third joints about as long as 
the basal. The maxille form a basal joint, throwing off a three-jointed 
palpus, and an inner lobe armed with stiff bristles, reaching to the end 
of the second joint of the palpus. The two-jointed labial palpi reach 
to as far as the middle of the brush-like lobe of the maxille ;_ the second 
joint is about as long, but half as wide, as the basal. The middle of each 
segment, especially the third to the seventh above and below, with a 
transverse callous spot. The upper side of the first abdominal segment 
has a very narrow oblong square area impressed uponit. The callous 
spot is best marked on the fifth segment, consisting of an area about 
one third as long as broad, with a square, shallow sinus posteriorly, 
and with the sides projected inwards ; it consists of tto series of callous 
spots, the outer forming the limits of the area as above described, and 
the inner series forming a simple transverse, narrow, lanceolate, oval 
spot. The callous spot onthe under side has a sinus in front, but 
slightly rounded behind. The one on the seventh segment (below) is 
but little more than one-half as wide, with a broad sinus on the hind 
edge, and with the sides directed obliquely inwards. Terminal segment 
very sinall, half as wide, and one-fourth as long as penultimate segment. 
Nine spiracles, the first on front edge of second thoracic (mesothoracic) 
segment. Length when fally grown, 15 inches. 
This larva may be kuown from that of Rhagium lineatum by its Jack 
of any thoracie feet and by its much longer, more cylindrical body, and 
differs at once by the long, square head, that of Rhagium rounding in 
front; by the wider clypeus, and proportionately wider and shorter 
labrum. The palpi and antennie do not differ much. The callous spots 
on the abdominal segments are smaller and otherwise different from 
those in Rhagium. 
Pupa.—The pupa is far advanced, being nearly ready to change to a 
beetle, the body becoming dusky and horn-colored, while the character- 
istic dark spots have already appeared on the wing-covers. The antenne 
are coiled up three and a half times at the end between the fore and 
the middle pairs of legs, and the genus may be recognized by their 
great length and the deep excavation in the head between them, as 
well as by the lateral short spine on the prothorax. 
The wing-covers in my single specimen reach to the third abdominal 
seginent, and are’pressed obliquely to the side of the body. The salient 
portions of the upper side of the abdominal rings with fine spines. End 
of the body sinuate.
