BY THE REV. T. BLACKBURX. 103 



Another member of the group of A. sti'iatus^ Macl., [consisting 

 of species distinguished by the elytra having very strong strise 

 which are only feebly punctured, or rather laterally crenulate (the 

 Granulations obsolete near the apex)]. It is very much smaller 

 than st7'iatus, and smaller and of much more widely oval form 

 than queenslandicus. From pinguis it differs by the interstices of 

 its elytra being much less convex, and from diaperioides, Blackb., 

 (P.L.S.N.S.W. 1888, p. 1435), by the interstices not being punc- 

 tulate. From all the aboveraentioned species it differs by the 

 presence of distinctly traceable ocular sulci.

Elongatus ; sat parallelus, sat nitidus ; niger, elytris orichalceis 

 purpureo-foveatis, antennis pedibusque rufis ; capite sat sub- 

 tiliter nee crebre punctulato, supra antennarum basin parum 

 reflexo ; oculis quam antennarum articuli basalis longitudine 

 magis inter se remotis ; sulcis ocularibus profundis, ante 

 oculos positis ; antennis quam corporis dimidium multo 

 brevioribus apicem versus sat fortiter incrassatis, articulo 3° 

 quam 5"^ multo longiori ; prothorace minus convexo, quam 

 longiori fere duplo (postice quam antice duabus partibus) 

 latiori, crebre subfortiter punctulato, antice leviter sinuatim 

 emarginato, a basi antrorsum subarcuatim angustato, basi 

 media sat anguste sublobata,angulis bene deterrainatis; elytris 

 seriatim foveolatis, foveolis insequalibus (nonnullis elongato- 

 sulciformibus), interstitiis planis sparsim subtiliter punctu- 

 latis ; prosterno medio antice carinato ; metasterno et 

 abdomine antice in medio sat fortiter punctulatis ; tarsorum 

 posticorum articulo basali quam ceteri conjuncti paullo 

 breviori. [Long. 5-5J, lat. 2J-2| lines. 



This very distinct and remarkably fine species may be at once 

 distinguished from all its congeners by the unusual sculpture of 

 its elytra, many of the seriate punctures taking the form of long 

 deep sulci. It is allied to A. variolaris, Pasc.
