Rhynchophorous Coleoptera of Japan. 85 
margin with two prominent tubercles in middle; surface uni- 
formly convex, not gibbous, anteriorly with scattered asperate 
elevations, forming a patch angulately produced behind but not 
reaching very near base, interstices and remainder of surface finely 
reticulate and rugosely punctured, with thin covering of scales 
and hairs. Scutellum very small, triangular. Elytra as wide as 
prothorax, and not quite half as long again, slightly and separately 
rounded at base, humeral angles rather obtuse, but not rounded, 
shoulders finely elevated, sides nearly straight and subparallel to 
posterior third, then broadly rounded to apex ; surface transversely 
convex, subcylindrical to behind middle, then obliquely decli- 
vous and convex to apex, with distinct rows of punctures, the 
outer ones obsolete towards apex, interstices narrow, finely 
multipunctate and squamous, with asingle series of scattered erect 
setee. Legs fuscous with tarsi testaceous, 
This species can be distinguished from other described 
Cryphali, in which the eyes are emarginate and the elytra 
not rounded from base to apex, by the two tubercles 
on the anterior margin of the prothorax. Amone the 
European species it is most like U. abietis, Ratz, but is 
much smaller, with the elytral stris not impressed, and 
the antennal club and legs darker. The transverse 
carina which borders the vertex of the head in front 
occurs in some Ceylonese species in my hands, and is 
probably a sexual character. As with other Oriental 
Oryphali, the joints of the antennal club have a rounded 
margin on their superior surface, which is less evident 
below. In this respect they approach Thomson’s sub- 
genus Hrnoporus, which can be characterised by the non- 
emarginate eyes alone. 
HyrorHenemus, Westw. 
I take this genus, as has been done by Leconte and 
others, to be inclusive of Hichhoft’s genus Stephano- 
deres, which it is not possible to separate by means of 
the number of articulations in the antennal funiculus. 
But it is not to be supposed, as Leconte has suggested, 
that the variations of this structure are of no generic 
value in Scolytide. In the majority of genera which 
can be separated by them, there are other structural 
features, or at least a difference of facies, which tend to 
show that they are a reliable guide. In the Hypothenemi,
