channel; the elytra are of equal width with the protho- 
rax, and are more thickly produced than the other parts 
of the body; they have the lateral margins nearly 
parallel, the disc marked with several very faint longitu- 
dinal carine, and the sutural portion is flattened. 
The legs are moderately slender, the anterior tibie 
with a few small irregular teeth, and the four hind ones 
with a small spine in the middle of their outer edge. 
This species is destitute of wings.

This species is nearly allied to LD. crenatus, but differs 
from it in the narrower and much less convex form of 
the male, which has a much smaller head and smaller 
mandibles; it has also the upper surface of the body 
(especially of the head and prothorax) much more 
strongly and closely punctured; the labrum, conically 
produced, is also smaller, and the mandibles are less 
strongly toothed at the apex. It is distinguished from 
the male of Ji. obtusatus, and its allies, both by its shorter 
form and differently constructed mandibles. The head 
is transverse; the anterior portion forming a large 
semicircular depressed space, extending from the outer 
angles of the base of the mandibles nearly to the hind mar- 
ein ofthe head; the front of this space is nearly smooth, 
but the hind part is covered with widely dispersed circular 
punctures; the lateral margins of the head in front of the 
eyes are oblique and thin, rounded off to the front incision
