the prostcrnum is broadly impressed bctAveen the coxtB, 

 broadly and squarely truncated behind, Avith the angles a

Precise locality unknown. 



It appears to me that there are two species of Nycte- 

 ropus confounded in collections under N. antliraciiius, 

 Klug. 



In the one (iV. anthr acinus, Klug) the colour is 

 shining black, usually with a tinge of green or dark 

 blue; the head more strongly and rugosely punctured, 

 the groove at each side less clean and distinct ; the epis- 

 tomal suture faint but visible ; the prothorax a little less 

 convex, and less rounded at the sides behind the middle ; 

 the elytra are not so convex at the base, and the sides are 

 more obliquely narrowed behind ; the flanks of the meso- 

 thorax are distinctly rugose punctate ; the prosternal 

 process is nearly plane, and is very distinctly prolonged 

 and somewhat broadly truncated behind. 



Long. 7^—10^ lin. 



In the other (iV! confusus, n. sp.) the colour is entirely 

 shining black ; the head finely and not at all rugosely 

 punctured ; the groove at each side is clearly and deeply 

 impressed and extends nearly up to the anterior border ; 

 the epistoma is completely confounded with the front ; the 

 flanks of the mesothorax are quite smooth ; the prosternal 

 process is not produced and is rounded behind, and there 

 is a well-defined groove extending round the sides of its 

 hinder half and partly inclosing a well-marked round 

 depression. 



Long. 7 1 — 8 1 lin. 



CNODALONINvE. 



Three out of the following four new genera have hitherto 

 been confounded with Camaria. They may all at once 

 be distinguished from that genus by the epipleural fold of 

 the elytra rapidly expanded at the base, completely attain- 

 ing the humeral angle.
