This is closely similar to F. rattus and P. hatuensis, but 

 generally rather darker in colour, and distinguishable by 

 the rather larger and more distinct punctures with which 

 the pronotum is covered. It is also smaller than P. rattus 

 and larger than P. hatuensis and differs from the former 

 by its very shining and finely facetted eyes and the more 

 rounded sides of the pronotum, and from the latter by the 

 finer and less deep puncturation of the elytra. 



PJiaeochroops hatuensis, sp. n. 



Pyriformis, fusco-rufus, hand dense fulvo-hirtns ; capite grosse 

 pimctato, oculis nitidis, prothorace brevi, dense punctate, lateribus 

 postice laevissime arcuatis ; elytris grosse et profunde rugose punc- 

 tatis, singulo lineis tribus longitudinalibus vix elevatis instructo, 

 marginibus vix ciliatis.

This is extremely close to P. niasianus, but a little 

 smaller on the average and a shade lighter in colour, with 

 longer and more evident pubescence upon the upper 

 surface. The punctures of the prothorax are more 

 numerous and those of the elytra deeper and rougher. 



PhaeocTiroops mentaweiensis, sp. n. 



Pyriformis, fusco-brunneus, sat parce fulvo-setosus ; capite rugose 

 punctato, clypeo brevi, oculis baud nitidis, grosse granulatis, pro- 

 thorace brevi, dense punctato, postice lato, lateribus vix arcuatis, 

 angulis posticis prominentibus ; elytris dense et rugose punctatis, 

 singulo lineis tribus longitudinalibus vix elevatis instructo, mar- 

 ginibus vix ciliatis.

This species is at first sight exactly like P. niasianus, 

 but the eyes are more coarsely facetted and not glossy, 

 the clypeus is more finely and rugosely punctured, and 

 the elytra are more coarsely and rugosely sculptured, with 

 rather sharper costae.
