is a pecaliavity about its surface, — wliicli is subopake 
throughout the anterior half, whilst the elytra are slightly 
shining, and just appreciably even subasnescent (calling 
faintly to mind certain of the Madeiran Caulotriipides). 
The underside, too, is rather singularly modified according 
to the sex, — the metasternum in the females being a little 
concave posteriorly, and furnished in the middle with a 
minute, isolated keel, abru])tly terminated in front ; whilst 
in the opposite sex the keel is absent, but the concavity is 
larger (extending through the first segment of the abdo- 
men). 
110. Xenomi:\ietes (Woilaston, Trans. Ent. Soc. 
Lond. 35. 1873). — Xenomimetes is a genus which was 
detected by J\lr. G. Lewis in Japan, — where indeed the 
only representative of it which I have hitherto seen would 
ajipear to be locally abundant, and (miless I am much 
mistaken) of pine-infesting habits. In this latter respect 
it consequently resembles Eremotes and Bracliytemnus, 
with the former of which it has several jioints (though 
perhaps only superficial ones) in common. It may easily 
be recognized by its type being elongate, narrow, and 
parallel, as well as somewhat opake and very densely 
sculptured, — it being also (when viewed beneath a high 
magnifying poAver) minutely pubescent, and asperated, 
towards the hinder apex (where the elytra are separately, 
and conspicuously, rounded-off, causing them to appear 
almost divaricate). The rostrum is rather peculiar in its 
construction, — being very short, but nevertheless quite 
parallel, and suddenh/ much narrower than the head; the 
eyes are extremely jirominent; the club (unlike that of 
Eremotes and oi \\\q RJiyyicoli) is rounded and abrupt, the 
antennae being comparativeh/ slender ; the legs (particularly 
as regards the tarsi) are a good deal elongated ; the tibi;i3 
(more especially however the anterior pair) are elongated 
and subflexuose ; and the coxa3 are but slightly separated, — 
the front ones indeed being not more so than in Rlij/ncolus, 
whilst the two hinder pairs (which are about equidistant) 
are by no means very remote.
