trum, although thus abbreviated, being nevertheless sub- 
parallel, rather than triangular, as well as slightly concave 
in the niidJle, and most curiously ■polished (and unsculp- 
tured) at the base ; for its eyes being, as in Spharocorynes^ 
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 deejily and coarsely 
sulcate-punctate, and obtusely rounded and minutely 
asperated posteriorly ; for its tibite (at any rate the front 
pair) being subflexuose ; and for its coxte, even the an- 
terior ones, being widely separated. The specimen which 
has furnished the diagnosis is from the collection of JNIr. 
Pascoe, and Avas captured by Mr. Wallace at Saylee on 
the north-west coast of New Guinea. 
107. Sph.t:rocorynes (Wollaston, Trans. Ent. Soc. 
Lond. 38. 1873). — Sphcerocorynes is one of the many 
genera the discovery of which is due to the researches of 
Mr. G. Lewis in Japan ; and it is conspicuous for its 
very short and channelled rostrum being nevertheless (as 
in Lissnpsis) parallel, rather than triangular, and for its 
antennte (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 subecpially 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 
tibiiB (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. Xexotrui'IS {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 ])arallel) out- 
line tending to remove it from these immediate grou]:)s ; 
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-
