Genera of the Cossonidce. 511 



family. I have already pointed out in what it principally 

 differs from Cheer or rhinus. It was detected by Mr. Or. 

 Lewis in the Japanese archipelago, namely at Nagasaki, 

 in the island of Kushiu. 



9. LYPRODES (nov. gen.). The single example from 

 which I have compiled the diagnosis of the present genus, 

 which was captured by Mr. 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 sculptured 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 which follow it), and in its 

 more elongated inetasternum (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 primd 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 coxae 

 being (especially as regards the front pair) greatly approxi- 

 mated, the present genus has much the primd facie aspect 

 of Phlceophagus ; nevertheless its funiculus is only 5-articu- 

 latc, its scutellum is conspicuous, and its rostrum and 

 (much thicker and more abbreviated) antennae are very
