is a peculiarity about * its surface, which is subopake 

 throughout the anterior half, whilst the elytra are slightly 

 shining, and just appreciably even subsenescent (calling 

 faintly to mind certain of the Madeiran Caulotrupides). 

 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, abruptly 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. XENOMIMETES (Wqllaston, Trans. Ent. Soc. 

 Lond. 35. 1873). Xenomimetes is a genus which was 

 detected by Mr. Gr. Lewis in Japan, where indeed the 

 only representative of it which I have hitherto seen would 

 appear to be locally abundant, and (unless I am much 

 mistaken) of pine-infesting habits. In this latter respect 

 it consequently resembles Eremotes and Brachytemnus, 

 with the former of which it has several points (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 power) minutely pubescent, and asperated, 

 towards the hinder apex (where the elytra are separately, 

 and conspicuously, rounded-off, causing them to appeal- 

 almost divaricate). The rostrum is rather peculiar in its 

 construction, being very short, but nevertheless quite 

 parallel, and suddenly much narrower than the head ; the 

 eyes are extremely prominent ; the club (unlike that of 

 Eremotes and of the Rhyncoli) is rounded and abrupt, the 

 antennae being comparatively slender ; the legs (particularly 

 as regards the tarsi) are a good deal elongated ; the tibiaa 

 (more especially however the anterior pair) are elongated 

 and subflexuose ; and the coxae are but slightly separated, 

 the front ones indeed being not more so than in Rhyncolus, 

 whilst the two hinder pairs (which are about equidistant) 

 are by no means very remote. 



111. EREMOTES (Wollaston, Trans. Ent. Soc. Lond. 2nd 

 Ser. v. 364. 1861).* The genus Eremotes., which may be 



* When compiling my ' Coleopt. Atlantidum,' in 1865, I changed the 

 name of this genus, from Eremotes, into Syntomocerus, feeling that the 

 title was so near to Eretmotes, of De Marseul, that there might be a risk
