■828 CARABID^ FROM DORRIGO, N.S W., 



origin; seventh faintly marked, but distinct on sides; first 

 interstice wide and bearing an elongate stride at base, eighth 

 wide on sides, narrow and carinate towards apex, ninth narrow 

 and seriate-punctate; basal border uniting with inner part of 

 first interstice, sharply raised at humeral angles; lateral border 

 narrow, reflexed. Apical ventral segment in ^ 4-, in 2 6-setose. 

 Length 6-6-7, breadth 2'5-2-75 mm. 



Hah. — Dorrigo. 



This species can be readily separated from the other species of 

 the genus by the great width of the lateral borders of the pro- 

 thorax. It resembles A. discoidalis Blkb., by the rectangular 

 basal angles of the prothorax, and the pattern of the elytra; but 

 differs by the postocular part of the orbits rising more sharply 

 from the neck, prothorax more transverse, less narrowed to base, 

 lateral borders much wider, humeral angles of elytra more 

 prominent, etc. 



DySTRICHOTHORAX VITTIPENNIS, n.sp. 



Slightly convex ; head obliquely constricted behind eyes, 

 strongly bi-impressed between eyes; prothorax subquadrate, much 

 wider across base (2-2 ram.) than across apex, basal angles rect- 

 angular, posterior marginal seta on border beside basal angle, 

 anterior seta wanting; elytra finely crenulate-striate, seventh 

 stria obsolete, interstices a little convex, third bipunctate, fifth 

 impunctate. Nitid, testaceous ; elytra more lightly coloured 

 than head and prothorax, 4-vittate; vittse black, inner vitta of 

 each elytron occupying second and third interstices, outer vitta 

 occupying seventh and eighth interstices ; apex and margin 

 testaceous. 



Head (l'75mm. across eyes) lightly transversely impressed 

 behind vertex, obliquely and decidedly narrowed behind eyes; 

 frontal impressions elongate, wide, parallel; vertex convex; eyes 

 prominent, inclosed behind. Prothorax broader than long 

 (1 7 X 2*3mra.), broadest a little before middle, very little narrowed 

 to base, strongly and roundly narrowed to apex; sides lightly 

 rounded anteriorly, oblique posteriorly; apex truncate between
