708 NOTES ON AUSTRALIAN COLEOPTERA, 



[While this memoir has been in the printer's hands I have 

 received from Mr. T. G. Sloane, of Sydney, the information that 

 having (in compliance with my request) compared the following 

 species with Fhlceocarahus Master si, MacL, he thinks they are 

 generically distinct. I do not doubt the correctness of Mr. Sloane's 

 opinion, and am very glad to have received it in time to insert 

 this note in the present memoir. Nevertheless, since these species 

 undoubtedly present the characters attributed to Phlceocarabus in 

 the published diagnosis of the genus, I think I do right in calling 

 them by the name, and leaving them to bear it until the genus is 

 re-characterized. I may say that Mr. Sloane draws attention to 

 the much smaller size of the 2nd joint of the antennae, and the 

 wider and more Xantho2:)hcea-\ike head in Phlosocarahus.^ 



Phlceocarabus unimaculatus, sp.nov. 



Sat elongatus ; sat depressus ; minus nitidus ; testaceus, capite 

 prothoraceque plus minus rufescentibus, elytris macula magna 

 communi nigra antrorsum in sutura producta ornatis ; capite pro- 

 thorace longiori, subtiliter sat sparsim punctulato ; prothorace 

 capite vix latiori, quam longiori vix latiori, basi quam antice 

 paullo angustiori, caoaliculato, transversim subtilissime strigoso, 

 latitudine majori paullo ante medium posit a, angulis (anticis sub- 

 rotundatis) posticis distinctis obtusis, lateribus sat rotundatis 

 pone medium vix sinuatis ; elytris sat fortiter striatis, apice 

 singulatim late rotundatis, interstitiis subconvexis, striis latera 

 versus obsoletis. [Long. 2|, lat. 1 line. 



Yar. Elytris juxta scutellum utrinque macula parva fusca 

 ornatis. 



The spot on the elytra is diamond-shaped, but when closely 

 examined its outline is seen to consist of about 16 distinct lines, 

 so that it is really a 16-sided figure; it extends laterally two- 

 thirds (or in some examples half) across each elytron ; its hind 

 point is about \ of the length of the suture from the apex of the 

 same and is produced (gradually narrowing) forward to a point
