350 MISCELLANEA ENTOMOLOGICA. 



impresso, thorace subquadrato medio breviter depresso ad 

 latera antice i-otundat opostice obsolete transversira impresso, 

 elytris fulvo-hirtis apice singulatim subrotundatis, tibiis 

 posterioribus extus obtuse terminatis. 

 Hab. Darling River. 

 This insect, perhaps, should be placed in the A. Hopei group, 

 the fact of the thorax being scarcely longer than broad, is my 

 only excuse for its present position. The thorax is peculiar. It 

 has in the centre of the median line a short broadish depression, 

 which seems to terminate at both ends in an ill-defined roundish 

 fovea. 



Akthropteeus depressus. 

 Long. 6 lin., lat. 2 lin. 



Rufo-piceus subnitidus latus subplanus dense punctatus pilis 

 brevibus vestitus, antennis latis sublongis, thorace subqua- 

 drato breviter canaliculate postice subangustato ^ngulis 

 anticis rotundatis, elytris longis truncatis, tibiis extus sub- 

 obtuse terminatis. 

 Hab. Tweed River. 

 This species is unlike any other. It is of a dark dullish red 

 colour, densely punctate, and thickly clothed with a short fulvous 

 pile. The antennas are broad, but owing to the length of the 

 joints, the width of each joint is not more than three times the 

 length. The thorax is almost broader than the length, nearly 

 truncate in front, and quite truncate behind, with the anterior 

 angles rounded and the posterior square, slightly narrowed 

 towards the base, and shortly canaliculate on the posterior half 

 of the median line. The fore tibiee are rather obtusely terminated 

 at the external angle, the others still more obtusely.
