elytra ; the latter gradually broader behind, and, towards the 

 apex, prominently raised at the suture, sti'iato-punctate, the 

 punctures large, squarish, and regularly arranged ; body 

 beneath pitchy, finely punctured \ legs and antennae paler.

I have only a single specimen of this insect ; but the pecu- 

 liar elevation of the el}i;ra posteriorly seems to mark it out as 

 a good species. 



Nearly related to Cestrinus is Asida serricollis^ Hope*; it 

 differs generically in the epipleurge of its elytra being broader 

 and horizontal or subhorizontal, and the mesostemum entire 

 anteriorly, the last joint of the labial palpi oblong-ovate and 

 somewhat acuminate, and the men turn trapeziform. I propose 

 to call this genus Achora. Opatrum denticolle^ Blanch, f, is 

 probably another species.

The character of the antennae at once separates this genus 

 from Diaperis ; to this may be added the peculiarly deep opa- 

 city of the coloration and the more flattened fomi. There is a 

 slight transverse elevation on the forehead of one of my spe- 

 cimens J.

t The males of a great many species of the subfamily, especially in the 

 genera Platydema and Ai-rhenoplita, have the head furnished with two 

 short horns, either between the eyes or a little above them. But in a 

 species from Brazil, lately given me by Alexander Fry, Esq., these horns 

 are transferred, so to say, to the apex of the prothorax. This remarkable 

 insect will form a new genus. I have adopted the name Arrhe/ioplita of 

 Kirby (Faun. Bor.-Amer. Ins. p. 23o) instead of HopJocephala, which had 

 been used years previou.sly by Cuvier for a genus of Ophidian?!.
