588 NEW SPECIES OF AUSTRALIAN COLEOPTERA, 



semcircularly emarginate, anterior angles obtuse, posterior acute; 

 disc and margins densely and rather coarsely but shallowly 

 punctate, disc with a very feeble median line ; margins rather 

 narrow, flat, not at all wrinkled, very feebly pubescent. ScuieUum 

 small, punctate. Elytra parallel to near apex, scarcely wider than 

 prothorax, mai'gins extremely narrow; middle somewhat flattened, 

 suture feebly raised and softly shining; each with three narrow 

 shining cost?e disappearing towards apex, and irregular through- 

 out, the intermediate feebler than the others; interspaces with 

 numerous very minute setose granules, very minutely punctate 

 and indistinctly transversely wrinkled. Bod}' beneath and legs 

 minutely pubescent, the former with punctures above the average 

 size in other species and obsoletely corrugate. Length \b\, width 

 9| mm. 



Hab. — Upper Ord River : E. Kimberley (Mr. R. Helms). 



Of the loevicoUis type, but easily distinguished by its non- 

 wrinkled prothoracic margins (in some lights appearing dark 

 brown) and almost entire absence of elytral margins. The almost 

 microscopic granules on the elytra are not at all irregular in size. 



XYLOPHILID^.. 



Mr. T. L. Casey has recently* divided the American species of 

 Xylophilus into thirteen genera (exclusive of Xylofhilus itself), of 

 which twelve are characterised as new. At the same time he 

 remarks : — " The species of the various genera adhere closely in 

 general appearance to the type form." If Mr. Casey's genera are 

 to be recognised, many genera will be required to contain the 

 Australian species, and this, I think, is highly undesirable. The 

 antennae and eyes are very variable, both sexually and specifically; 

 and any division of the group into genera which takes these 

 organs as its principal characters is likely to prove very mislead- 

 ing. I must here enter a strong protest against the splitting up 

 of AnthiGus\ as proposed by Mr. Casey, pi'incipally on account of 

 mesosternal modifications.
