“The thirteenth segment is pointed, and very much narrower than 
the others. 
“This larva is very agile and.quick in its movements, and, when 
“disturbed, moves the hinder part of its body quickly from side to side. 
It feeds on the inner portion of the bark of the Scotch-fir, when this is 
in a decaying condition.” 
The first larva that I saw was found by Mr. Hislop, who suspected 
that it was the larva of Dendrophagus, but did not succeed in proving 
it to be so by rearing it. The larve described by C. von Gernet (loc. 
cit. supra), which were found under the bark of a fallen birch near 
Murino (in the Government of St. Petersburgh), evidently belong to 
another genus. 
. Description of the pupa: yellowish-white, oblong, depressed, and 
tapered towards the tail. Head deflected under the thorax, with a 
hair-tipped spine in front of each eye. Eyes brown. Antenne—first 
joint extending at right angles to the head, the others at right angles 
to the first joint and parallel with the body, passing over the two first 
pair of legs and under the third; apex of each joint, except the first 
with a circlet of short, stout spines. 
Pronotum quadrate, excavated in centre, angles rounded, margin 
furnished with hair-tipped spines, two from the front margin; at each 
anterior angle a group of three, with their bases connected by a mem- 
branous expansion ; at each posterior angle a group of two, with their 
bases connected as in the anterior spines. . Elytra not conspicuous, 
closely appressed, and directed under the sternum. 
Legs curved under the thorax. Femora protruding and directed 
backwards ; from the apex of each spine four tubercles, the two an- 
terior of which are hair-tipped, except in the third pair of legs, where 
only the lower anterior tubercle is hair-tipped. 
Hind-body with a central depressed line; each segment with, 
above the sides, a depressed tubercle pointing backwards, and with an 
oblique, raised line running from the base of each tubercle towards the 
preceding segment. Fourth, fifth, and sixth segments with a long 
hair-tipped spine on the extreme side, below the tubercle. 
Under-side. Hlytra reaching to nearly the fourth segment of the 
hind-body. ' 
Length 4 lines. 
The larva, when about te assume the pupal state, attaches itself 
firmly to a piece of bark by the thirteenth segment, and the pupa re- 
mains attached by its anal segment to the larva-skin.
