parum latiori, medio longitudinaliter profunde sulcato, antice 

 parum emarginato, angulis anticis obtusis, lateribus fortiter rotun- 

 datis mox ante basin sinnatis, angulis posticis rainutis subdenti- 

 formibus, sulco laterali lato profundo, sulco utrinque basali minus 

 elongate ; elytris profunde striatis, striis fortiter crenulatis, inter- 

 stitiis fortiter convexis. [Long. 2h, lat. 1 line (vix). 



Differs from A. simplex by its shorter and wider prothorax. of 

 which the sulcus within the lateral margin is much stronger, and 

 by its still more deeply striate elytra, the striae of the same being 

 crenulate internally, and the interstices very much more convex ; 

 the legs (especially the hind femora) are of a darker colour. From 

 A. australis, Chaud., and D. Thouzeti and vicina, Cast., it differs 

 by its unicolorous antennae and smaller size. Of Sir W. Macleay's 

 species only A, ater and A. angustior are described as not having 

 the elytral striae simple ; from the former of these it differs by its 

 elytra much wider than the prothorax, and from the latter by its 

 prothorax not " longer than the width." The median sulcus of 

 the prothorax (as in A. simplex) is abbreviated at both ends.

 The above change in nomenclature seems to be required.

Prosopogmus. 



Masters' Catalogue attributes 10 Australian species to this 

 genus (or sub-genus), of which at most 3 — Boisduvali, Cast., 

 Reichei, Cast., (these two probably not specifically distinct inter 

 se), and harjyaloides, Chaud., — seem to be entitled to their place. 

 The error has probably arisen from the fact that de Chaudoir 

 (Ann. Mus. Gen. 1874, p. 594) has most unaccountably placed
