Genera of the CossonidcB. 511 
family. I have already pointed out in what it principally 
differs from ChcBrorrhinus. It was detected by Mr. Gr. 
Lewis in the Japanese archipelago, — namely at Nagasaki, 
in the island of Kusliiu. 
9. Lyprodes {nov. gen.^. — The single example from 
which I have compiled the diagnosis of the present genus, 
which was captui-ed by INIr. Wallace in Sula, one of the 
islands of the Malay archipelago, has been communicated 
by Mr. Pascoe ; and it is especially important as supply- 
ing another well-defined type in the subfamily Pentar- 
thrides — in which the funiculus is only 5-articulate. More- 
over its opake and deeply scidptured surface, .which is 
densely besmeared with mud-like scales (or, as it were, a 
kind of dirty-whitish, scaly deposit), added to its almost 
obsolete scutellum, and its thick, abbreviated feet (the first 
joint of which is short, and the third one wide and very 
deeply bilobed), place it in the immediate vicinity of 
Pentacoptus and Cheer or rhinus. It is abundantly dis- 
tinct, however, from both of those groups, not merely in 
its much narrower and cylindric body (which is of nearly 
equal breadth throughout), but likewise in its much longer 
and slenderer rostrum, its less incrassated and less abbre- 
viated antennae (which have their second funiculus-joint 
appreciably longer than those Avhich follow it), and in its 
more elongated metasternum (which indeed is scarcely 
shorter than that of Pentarthrum and Stenotrupis). Its 
eyes, although prominent, are less remarkably so than in 
Pentacoptus ; and its elytral interstices are not so costate. 
In prima facie aspect the insect calls to mind what we 
might almost suppose to be an exceedingly diminutive 
state of the European Lyprus cylindricus, — a circumstance 
which, however fanciful, has suggested both its generic 
and specific names. 
10. Phlceophagomorphus {nov. gen.). — In its rather 
lengthened cylindric-ovate outline, which is narrowed in 
front and gradually expanded behind (the prothorax being 
considerably reduced in size, and much narrower than the 
elytra), as well as in the fact of its four anterior coxte 
being (especially as regards the front pair) greatly approxi- 
mated, the present genus has much the prima facie aspect 
oi Phlceophagus ; nevertheless its funiculus is only 5-articu- 
late, its scutellum is conspicuous, and its rostrum and 
(much thicker and more abbreviated) antennae are very
