204 THE GENERA AND SPECIES OF AMYCTERID^, 



by the thorax. The sculpture of the elytra also is more distinct 

 than in mirahiUs, the tubercles are larger, and the apex is not 

 niucronate. 



The only specimen I know of this insect is in the late Mr. 

 MacLeay's collection, and there is nothing to indicate its habitat. 



4. — PSALIDURA COXII. 



Oblongo-elliptica nigra nigro-setosa pai^ce squamosa, capite 

 brevi, thorace confertim medio minus crebre tuberculato, 

 elytris seriatim rude punctatis interstitiis seriatim tubercu- 

 latis alternis elevatioribus. 

 Mas : gula cornuta, forfice anali valido longo. 

 Femina : thorace medio sparsim rugoso-tuberculato. 

 Long. 12 lin., lat. 4| lin. 

 Hab. Dabee. 



This species seems to be abundant at Dabee, and probably all 

 through the Mudgee district. It differs from P. mirabills not 

 only in size, but in the more coarsely tuberculated thorax, in the 

 more regularly marked and less rugose elytra, and in the much 

 longer anal forceps of the male. The tubercles on the thorax of 

 the female are somewhat distant and rugose in the middle, in 

 other respects the female only difiers from the male in the 

 manner common to all the species, viz : — it is shorter, bi'oader, 

 and has the thorax less lobed on the top of the head. 



The species is named after Dr. James C. Cox, from whom I 

 first received specimens of the insect.
