I think, two species) may be represented by the specimens before 

 me from Pinjarrah and JNIount Barker respectively. 



117. A. RTFicoLLis, n.sp. 



Depressed; head finely shagreened and minutely punctulate; 

 prothorax short, smooth, lightly emarginate, middle of base hardly 

 projecting, posterior angles obtuse; elytra lightly striate, shagreened 

 and minutely punctulate. Head, prothorax, under surface, tibiae, 

 tarsi and antennte ferruginous ; elytra piceous-black, apex, a 

 narrow lateral margin and two discoidal maculae testaceous ; 

 inflexed margin of elytra and femora pale testaceous (the maculae 

 of the elytra variable in size, placed before middle, extending 

 across interstices 2 6, suboval in shape with a shorter projecting 

 part on fifth and sixth interstices ; testaceous apical margin 

 wide, projecting triangularly forward in middle). 



Head not short ; front depressed, not rugulose, lightly and 

 widely impressed on each side ; occiput convex ; eyes globose, 

 prominent. Prothorax transverse (1 x 1-5 mm.), widest at anterior 

 third, a little convex, very finely shagreened and minutely setigero- 

 punctate; explanate margins not wide, hardly rougher than disc; 

 sides roundly narrowed anteriorly, obliquely narrowed posteriorly, 

 not sinuate before basal angles; anterior mariiin lightly and evenly 

 emarginate; anterior angles widely rounded; base roundly and 

 weakly lobate in middle, sloping roundly obliquely forward to 

 basal angle on each side; basal angles roundly obtuse; median 

 line strongly impressed. Elytra much wider than prothorax 

 (34 X 2-5 mm.), widest about posterior third, a little narrowed to 

 base, roundly truncate at apex ; base truncate on each side 

 (shoulders hardly advanced); humeral curve of border wide, hardly 

 subangulate. 



Length -5-6, breadth 2-27 mm. 



Hab. — Mount Barker (Lea). 



Allied to A. mrtida, Erichs.,from which the following differences 

 readily distinguish it: — The red colour of the prothorax; head 

 less strongly punctate ; prothorax much smoother, explanate 

 margins not rugose, sides more evenly rounded, posterior angles 

 widely obtuse; elytra proportionately narrower and more elongate,
