240 NEW SPECIES OP AUSTRALIAN COLEOPTERA, IT.,. 



G. opacicollis MacL— Co-types in the Macleay and Australian 

 Museums, from Gayndah, Q. 



C. Walckenaerii Hope (mis-spelt in Mr. Masters' Catalogue) is 

 the common species found near Sydney. Its range seems to be 

 from the Hawkesbury River to Botany and westward to the 

 Kurrajocig, where it is very plentiful. 



Since the publication of Mr. Masters' Catalogue, one species 

 only has so far been added, C. ceripennis Blackburn, which I 

 have taken in some numbers at Mt. Wilson, and sparingly round 

 Blackheath (kindly identified for me by Mr. Blackburn). I have- 

 seen one specimen, captured by Mr. Taylor, from North Sydney,, 

 and there are two specimens in the Macleay Museum, from New- 

 castle. To these I propose to add the names of nine new species, 

 described below, so that if C. jraternalis, C. valgipes, C. acut- 

 angulus and C. cericollis are to be considered as good species, we 

 have recorded forty-three members of this genus; or if the first 

 two of these be considered as synonyms of C. errans, we shall 

 have forty-one; and there is little doubt but that more forms will 

 come to light. 



Cardiothorax angusticollis, n.sp. (Plate xx., fig.8). 



Elongate-oval, narrow, coppery-bronze, shining. Legs and 

 abdomen black. Head scarcely depressed on front; palpi large- 

 and prominent; antennae stout and pilose; third joint about one 

 and a half times the fourth; joints nine to thirteenth increasingly 

 bigger, thirteenth much the largest and ovate. 



Prothorax longer than wide, widest before the middle, apex 

 scarcely emarginate, front angles widely obtuse and rounded;, 

 base sinuate, feebly emarginate, narrower than apex; hind angles- 

 obtuse without dentation. Sides slightly rounded, foliaceous 

 margins almost obsolete and without any separating sulcus. Very 

 narrow reflexed border, disc flat, medial channel faintly impressed 

 at base and apex, on each side of this a strongly impressed 

 irregularly interrupted line. Scutellum large, transverse, curvi- 

 linear triangular, not depressed below elytra. Elytra narrowly 

 ovate, broader than prothorax; humeral angles obtusely rounded,.
