 base, anterior angles depressed and obtuse, posterior widely 

 obtuse, disc minutely punctate, medial line faint. Scutellum 

 arcuate-triangular. Elytra of same width as prothorax at base, 

 and more than thrice as long, punctate sulcate, the punctures

 of the intervals, the first two intervals wider and flatter than 

 the rest, but with them continuous to and strongly carinate on 

 af)ex, intervals microscopically and closely punctate; prosternum

^rt6. —Melville Island (W. D. Dodd). 



Nine specimens, sent from the South Australian Museum, 

 differ from all described Australian species in the deep sulci, and 

 strongly raised elytra! intervals. It is nearest to A. striatns 

 Macl., from which it obviously differs in the laiger seriate punc- 

 tures, deeper sulci, and less nitid surface. Types in the South 

 Australian Museum.
