Genera and Species of Coleoptera. 327 



Chaetopteetx [Helopidse]. 

 Westwood, Arc. Entom. i. p. 43. 



Cliartopteryx binodosus. 



C. obovatus, fusco-cupreus ; elytris basi bigibberis. 



Hab. Queensland. 



Obovate dark copper-brown, irregularly punctured with numerous 

 nearly erect hairs arising from the punctures ; head with a transverse 

 impression above the epistome, roughly but rather sparingly punctured ; 

 antennae black, not reaching beyond the base of the prothorax, the four 

 terminal joints dilated ; prothorax transverse, sinuate in front, anterior 

 angles produced, the posterior rather acute, with shallow scattered 

 punctures ; scutellum subtriangular ; elytra very convex, a large com- 

 pressed elevated protuberance near the base of each, rather dilated, 

 posteriorly covered with large rough punctures; legs hairy; body 

 beneath less coppery and more slightly punctured, with fewer hairs. 

 Length 5 lines. 



This species differs considerably in habit from C. Childrenii, West., 

 and in that respect bears a marked resemblance to Thecacerus bino- 

 dosus, Lap., belonging to the same family. It may be necessary 

 eventually to propose a new genus for its reception. 



Cyphaletjs [Helopidae]. 

 Westwood, Arc. Entom. i. p. 43. 



Cyphaleus insignitus. 



C. ovatus, niger, subnitidus ; elytris viridi-metallicis, nitidissimis. 



Hab. Queensland. 



Ovate, everywhere black except the elytra, slightly shining on the 

 prothorax and beneath, the upper surface irregularly covered with deep 

 round punctures, most numerous on the sides of the prothorax pos- 

 teriorly and base of the elytra, but which gradually disappear towards 

 the apex, the punctures small on the head, prothorax, and scutellum, 

 but nearly all with a stiff' setose hair arising from the interior of each ; 

 elytra veiy convex, dark metallic green with purple and violet reflec- 

 tions ; legs bluish black, finely punctured. Length 9 lines. 



Probably most akin to C. iopterus, Westw., but is narrower, with 

 the prothorax more convex, &c. In C. iopterus, too, the prothorax 

 is a dark metallic green, and the elytra a very deep purple with 

 violet reflections, particularly at the sides. The figure of Professor 

 "Westwood in the 'Arcana,' at pi. 12. f. 1 (not referred to in the 

 text), somewhat resembles the present, but is certainly not applicable 

 to either of the three species there enumerated.
