 more deeply emarginate. The genus Paiielus is new to Austi'alia, 

 and is a member of Lacordaire's " Groupe " Minthophilides. 



It is just possible that this is the species on which Sir W. 

 Macleay founded his name Temnoplectron pyg)/i(Eii?n, the descrip- 

 tion of which is too brief for cei'tain identification. Sir W, 

 Macleay, however, says of that insect, " disk of prothorax very 

 minutely punctate," a statement which inter alia does not apply 

 satisfactorily to the present species.

In respect of form and sculpture this species is very close to C. 

 mcelius, Er., but differs from it in the base of its prothorax not 

 being margined ; also in the median channel of that segment 

 being more strongly defined and the impression near the front 

 margin being feebler and less transverse, the latter appearing as 

 little more than a deepening of the median channel rather than a
