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

 apex, prominently raised at the suture, striato-punctate, the 

 punctures large, squarish, and regularly arranged ; body 

 beneath pitchy, finely punctured ; legs and antennas paler. 

 Length 2| lines. 



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

 liar elevation of the elytra posteriorly seems to mark it out as 

 a good species. 



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

 differs generically in the epipleurse of its elytra being broader 

 and horizontal or subhorizontal, and the mesosternum entire 

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

 somewhat acuminate, and the mentum trapeziform. I propose 

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

 probably another species.

 Tarsi postici art. primo elongate 



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 form. There is a 

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

 cimens J. 



Typhobia fidiginea. 



A. ovalis, subdepressa, nigra, opaca; corpore infra, antennis pedi-

Hob. Queensland ; Victoria. 



Rather narrowly oval, subdepressed, black, opaque ; head 

 somewhat pitchy, finely punctured ; prothorax impunctate, 

 anterior angles slightly produced, the lateral marginal line 

 glossy reddish testaceous ; scutellum transversely triangular ; 

 elytra finely striate-punctate, the punctures minute, the inter- 

 vals of the striae broad and very slightly convex ; body be-

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

 genera Platydema and Arrhenoplita, 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 Arrhenoplita of 

 Kirby (Faun. Bor.-Amer. Ins. p. 235) instead of Hoplocephala, which had 

 been used years previously by Cuvier for a genus of Ophidians.
