Cardiothorax caperatus, Pascoe. 



Larger than encephalits, Pasc, and ])roportionately bi'oader ; the 

 prothorax is relatively shorter and wider, distinctly more rounded at 

 the sides, and more abruptly curvedly contracted at the base; the tarsi 

 are also relatively much stouter. 



Cardiothorax ANOULATrs, sp. n. 



Very near to C. simulans, Haag ; it differs in having the prothorax wider, more 

 deeply, and distinctly angularly, emargiuate in front, the sides moi-e strongly rounded, 

 the margins much more strongly thickened, the apical margin ohsolete at the middle; 

 the discal markings more numerous and much more deeply impressed. 



Long. 7i lines. 

 North Australia. 



Cardiothorax grai^dis, sp. n. 



(? . Besides the characters mentioned in the preceding table as distinguishing 

 this species from C. Castelnaudi, Pasc, the elytra are very distinctly bronzed-black, 

 and more or less nitid : the intervals distinctly crenulated, more costiform, and 

 alternately very narrow. 



The $ in both species has the hind tibiae straight, or nearly so ; and the form 

 less parallel. Long. 9j to lOj lines. 



New South Wales. 



Cardiothorax 'Walke]!^^ri, Hope {Adelium Kirhyi, Sol, and 

 possibly A. dilaticoUe, Guerin). 



This species is somewhat variable as to form and size ; the pro- 

 thorax is always ample, strongly rounded at the sides, the well developed 

 foliaceous margins separated from the disc by a strongly marked 

 crescent-shaped sulcation ; the hind angles dentiform : the elytral 

 costae are sometimes punctured, the punctures crenulating the sides of 

 the intervals. In what I take to be the ^ the intermediate and pos- 

 terior tibise are compressed, the latter very strongly so, but are not 

 perceptibly flexuous. 



Cardiothorax ^ricollis, Pascoe. 



Is most probably only a variety of the preceding, having a more 

 shining surface, and the prothorax a little bronzed.
