Oriental Scolytidx of economre importance. 427 
sides rounded, lateral margins distinct but not prominent from the 
base to the middle, dorsum convex, with very close but not coarse 
punctuation, and a subcarinate median line from the base to the 
middle, base impressed for the elytra. Scutellum indistinguishable. 
Elytra twice as long as the prothorax, separately and strongly 
rounded at base with narrow raised crenate margins carried back 
obliquely and sinuate at the sides over the metasternum, the sides 
sinuate but subparallel, obliquely inflexed at the apex, which forms 
an angle at the suture but is not produced ; surface with moderately 
deep incised shining crenate striz, the interstices subconvex, with 
close and rather fine punctures bearing very short and inconspicuous. 
sete. Underside strongly punctured, and pubescent with short grey 
hairs. Legs robust, the anterior tibize widened apically, their upper 
border crenate, the upper apical angle with a backwardly-directed 
tooth ; middle and posterior tibiz with the upper border rounded 
and crenate.

The species has all the appearance of a Hylesinus, from 
which the structure of the antennal club separates it. 
Compared with D. curvifer, Walk., the nearest allied 
species known to me, it differs im the absence of the 
complete opacity characteristic of that species, in the 
much closer thoracic punctuation, less deeply incised 
elytral strize and more convex interstices, as well as in the 
non-mucronate elytral apex. Assuming the species to be 
correctly assigned to Diamerus, and I do not see any 
reason for separating it, one must infer that Diamerus and 
Hylesinus are somewhat nearly allied to each other.
