tram, although thus abbreviated, being nevertheless sub- 

 parallel, rather than triangular, as well as slightly concave 

 in the middle, and most curiously polished (and unsculp- 

 tured) at the base ; for its eyes being, as in Sph&rocorynes, 

 extremely prominent ; for its prothorax being large and 

 convex, about equally rounded at the sides, and of the 

 same breadth at its widest part as the elytra; for the 

 latter being shortly-cylindric, very deeply and coarsely 

 sulcate-punctate, and obtusely rounded and minutely 

 asperated posteriorly ; for its tibias (at any rate the front 

 pair) being subflexuose; and for its coxas, even the an- 

 terior ones, being widely separated. The specimen which 

 has furnished the diagnosis is from the collection of Mr. 

 Pascoe, and was captured by Mr. Wallace at Saylee on 

 the north-west coast of New Guinea. 



107. SPILEROCORYNES (Wollaston, Trans. Ent. Soc. 

 Lond. 38. 1873). Sph&rocorynes is one of the many 

 genera the discovery of which is due to the researches of 

 Mr. Gr. Lewis in Japan ; and it is conspicuous for its 

 very short and channelled rostrum being nevertheless (as 

 in Lissopsis) parallel, rather than triangular, and for its 

 antennas (which are thickened and considerably developed) 

 having their scape elongate, their funiculus abbreviated, 

 and their club large, rounded, and abrupt. Its eyes are 

 extremely prominent; its body (which is subcylindrical, 

 and comparatively lightly and delicately, though rather 

 closely, sculptured) is convex, just appreciably sericeous on 

 the elytra, and rather more evidently so beneath ; and its 

 legs are subequally separated at their base, the ante- 

 rior pair being a little more, and the hinder pair a little 

 less, remote than is usual amongst the Cossonids. Its 

 tibiaa (the front ones of which are slightly flexuose) are 

 rather long ; and its tarsi have their first joint considerably 

 lengthened, and the third one, although scarcely widened, 

 very minutely (but evidently) bilobed. 



108. XENOTRUPIS (nov. gen.}. The affinities of this 

 genus are somewhat difficult, its longer and less thickened 

 rostrum, which is gradually narrowed posteriorly, its less 

 incrassated head, and fusiform (instead of parallel) out- 

 line tending to remove it from these immediate groups ; 

 yet at the same time it has so much in common with 

 them in its convex, shining, deep-black, lightly sculptured 

 surface, its abrupt and compressed club, its largely de-
