as iV. kingi; Castelnau described the elytra of N. satanas as 

 having the third interstice bipunctate. By the aid of the data 

 that N. kifigi is a black species with the third elytral interstice 

 bipunctate, assisted by Chaudoir's comparative remarks with JV. 

 variicoUis and ^Y. satanas, I arrive at the conclusion that the 

 name is applicable to the species for which I have used it above. 

 It is a distinct species; compared with N. jyolitulus, Chaud., it is 

 more elongate, more convex, with the posterior puncture of the 

 third elytral interstice not nearly so near to the apex. 



Note. — Specimens from New England have the prothorax a 

 little shorter; sides subsinuate before base; basal angles more 

 marked; the elytra with basal border raised above lateral border 

 at humeral angles. It may be a distinct species, but I hesitate 

 to consider it so from the specimens available to me.

I venture to place N. ingratus, Chaud., between iV. kingi, 

 Chaud., and N. marginatus, Casteln. It is unknown to me in 

 nature. In the original diagnosis it is described as having the 

 prothorax a little longer and less rounded on the sides, the elytra 

 longer and less convex than N. marginata, Casteln.; the inter- 

 stices slightly and equally convex; the shoulders very slightly 

 dentate ; from the ' Supplement ' we learn further that it is 

 rather near N. politulus, Chaud., coloured the same, with a more 

 marked iridescent reflection on the elytra; prothorax narrower, 

 almost as long as broad. Length 18 mm. 



Hab. — Southern Australia.
