elytra; the posterior of them extends from the 2nd to the 5th 

 costa and interrupts the 3rd and 4th costse immediately behind 

 the middle of the elytra. The costsc (as in G. exilis) are wider 

 and less elevated than in most of the Australian Chalcophorites 

 (e.g., C. australasice); the 1st costa is siitural and entire, the 2nd 

 parallel with the 1st and entire, the 3rd twice interrupted and 

 joining the 2nd close to the apex, the 3rd once interrupted and 

 scarcely reaching into the apical \ of the elytra, the 5th near the 

 lateral margin and entire. It is just possible that the absence of 

 dust-like scales may be due to abrasion, but I think more probably 

 not. The hind tarsi and prosternum are as in C. exilis. There is 

 no trace of an abdominal plate like that of C. pistor. 



This insect is not, I think, very near any previously described ; 

 perhaps it comes nearest to C. Martini, Saund., and C. cerata, 

 Kerremans, both of which, however, differ from it, inter alia 

 muita, by their testaceous antennse. 



S. Australia; near Beltana (on the Southern border of the 

 Central Desert). 



AsTR^us Tepperi, Blackb. 



This species appears to be identical with A. Jansoni, v, de Poll. 

 The " jNIonographical Essay " in which it received the latter name 

 is dated 1889 ; my description was read to the Linnean Society 

 of N.S. Wales in December, 1889, but was not published till early 

 in 1890. My name therefore becomes a synonym. 



TENEBRIONID^E. 

 Hyocis nigra, sp.nov. 



Opaca ; nigra, pedibus plus minusve rufescentibus ; prothorace 

 fortiter transverso, canaliculato, lateribus minus arcuatis 

 postice baud sinuatis, angulis anticis prominulis posticis 

 rectis, basi late fortiter lobata ; elytris punctulato-striatis, 

 pnncturis in striis minoribus crebre positis, interstitiis vix 

 convexis. [Long. 1, lat. f line.
