elytra striate, shagreened, setigero-punctate, base emarginate in 

 middle and roundly advanced at shoulders. Head and disc of 

 prothorax, tibise, tarsi and antennae ferruginous (disc of prothorax 

 and vertex sometimes infuscate) ; elytra piceous-black, apex, a 

 narrow lateral margin and two large oval discoidal maculae 

 testaceous (discoidal macuUe extending across interstices 2-6, 

 testaceous apical margin wide — much wider on interstices 1-4 of 

 each elytron); femora and inflexed margin of elytra pale testaceous. 

 Head rather elongate, obliquely narrowed behind eyes; front 

 depressed, widely and lightly biimpressed; eyes prominent, hardly 

 globose. Prothorax much wider than head (1 3 x 1-8 mm.), widest 

 just behind anterior third, depres.sed; disc shagreened, .setigero- 

 punctulate, finely rugulose ; margins widely explanate, densel}'- 

 rugose-punctate, lightly upturned towards base; sides roundl}^ 

 subangulate at widest part, strongly roundly-obliquely narrowed 

 anteriorly, lightly narrowed and subsinuate posteriorly; anterior 

 margin deeply emarginate ; anterior angles projecting a little, 

 obtuse; base widely and feebly lobate in middle, obliquely truncate 

 on each side; basal angles subrectangular, obtuse at summit ; 

 median line strongly impressed. Elytra much wider than

 This species has a considerable superficial resemblance to 

 Trigonoihofs pacijica, Erichs. It seems to agree so closely with 

 the description given by Baron Chaudoir of the species he calls 

 A ( Lehia) mollis, Newm., that I think it may be the species he 

 had before him, but in that case I cannot agree with him in his 

 identification of it as A. mollis, which is, from Newman's 

 description, a species allied to and rather smaller than A. lutosa, 

 Newm., and, if so, having no resemblance to the species Chaudoir 

 described as A. mollis. The description I have given is founded 

 on specimens {^) from Mount Barker; the 9— judging from the 

 specimens before me — has the prothorax infuscate and not so long- 

 as the (J ; it is possible the sexes of two slight varieties (^but not,
