densely and finely punctulate. Piceous-brown, occiput and ex- 

 planate margins of prothorax more lightly coloured; elytra with 

 reflexed margins, a wavy fascia on discoidal third of each and 

 apex testaceous (the discoidal fasciae extending from first to 

 seventh interstices, narrow, of an irregular W-shape, sloping 

 lightly obliquely backwards external l}"-; the piceous ground colour 

 of the elytra projecting sharply and triangularly^ into the apical 

 testaceous margin about middle of each elytron); under surface 

 rather infuscate; coxae, femora and base of antennae testaceous; 

 tibiae, tarsi and antennse (excepting base) darker. 



Prothorax small, transverse (7x1-2 mm.), widest about anterior 

 third; di.sc finely shagreened; lateral margins widely explanate, 

 finely punctate; sides obsoletely angulate and setigero-punctate 

 at widest part, strongly and roundly narrow'ed anteriorly, lightly 

 narrowed posteriorly, usually subsinuate before basal angles; 

 anterior angles obtuse; base obliquely truncate on each side; basal 

 angles rectangular wdth summit rounded; median line stronglj' 

 impressed. Elytra greatly wider than prothorax (2-4 x 2 mm.), 

 lightly convex, finely setose and punctulate (the setae very fine 

 and short); striae obsolescent; shoulders rounded; base declivous 

 to peduncle. 



Length 3-8-4-3, breadth 1-8-2 mm. 



Hab. — Swan River, Rottnest Island, Mount Barker (Lea). 



Nearly allied to A. fenestrata, Blkb., from w^hich the markings 

 of the elytra readily distinguish it; the elytra are more convex 

 with the puncturation less marked; the prothorax is a little wider. 

 It should be noted that instead of four setigerous punctures on 

 the third interstice of the elytra, as is usual in the genus, only 

 one is perceptible; it is placed a little in front of the apical pale 

 margin (this being about the usual position of the second puncture 

 from the apex); the anterior puncture usually so noticeable about 

 the basal fourth of the third interstice seems quite wanting in 

 this species.
