convex and simple), its antenna) are more elongated and 
slender, inserted nearer to the apex of the rostrum, and 
Avith the (less compact) funiculus-joints (especially the 
second one) longer, its legs also (particularly as regards 
the tibire) are longer and thinner, and its feet have the 
third articulation more evidently expanded and bilobed, 
and the claws conspicuously more developed. The body 
moreover, instead of being coarsely, though sparingly, 
pubescent (with the pubescence developed on the elytra 
into elongate, erect seta}), is bald.*

1851). — In prima facie aspect this is one of the most 
remarkable genera of the CossonidcB Avith Avhich I am 
acquainted ; and, although European, it appears to be 
somewhat scarce in collections. I am however indebted 
to ]Mr. Gray and to jMr. E. W. Janson for the opportunity 
of examining several types — which, judging from labels 
Avhicli are appended to them, appear to have been 
captured by ^1. Hampe in Croatia. Before an accurate 
insjiection, it has much the appearance of a small and 
rather narrow Acalles, — its convex, ovate body, and nearly 
opake, reddish-brown surface (which is sparingly clothed 
with decumbent fulvo-cinereous pile, Avhich however is 
developed on the alternate interstices of the elytra into 
elongate erect bristles), giving it a character which is 
strongly suggestive of certain members of that group. Its 
rostrum is rather long and cylindrical ; its prothorax 
(which is narrower than the elytra, at any rate than the 
widest portion of them) is suboval, closely punctured, and 
even (being scarcely at all constricted behind the apex) ; 
its elytra are ovate and punctate-striated, with the inter- 
stices convex and remotely studded (at any rate as regards 
the alternate ones) with the elongate setre to.Avhich I have 
above alluded; its antenna; (which have tiieir scape robust, 
slightly curved, and considerably thickened towards the 
a])cx, and their second funiculus-joint not at all lengthened) 
are inserted a little before the middle of the rostrum ; its 
legs are a good deal incrassated ; its claws are exceedingly
