certain species of Cetomidce. 395 



impressed, the margins being thin and bent upwards, 

 the disc densely marked with small punctures and of a 

 dark red colour ; a small fine carina runs down the 

 middle of the disc, with two fine raised lines extending 

 from its hinder end to the angles in front of the eyes, 

 which, as well as the antenna, are black ; the front of 

 the cl^^peus is slightly emarginate. The prothorax is 

 brilliant green, finely punctured, and slightly bi-impressed 

 on the disc, the posterior half of its lateral edges sud- 

 denly angulated, behind which they are emarginate. 

 The scutellum is glossy green. The elytra are green 

 tinged with fulvous ; the shoulders black, from which 

 runs a slender carina to the black subapical tubercle ; 

 between this and the suture the disc is finely rugulose, the 

 rugosity forming indistinct longitudinal strife, the suture 

 itself narrow, slightly raised and dark green ; the podex 

 is orange-red, with the apical margin green. The body 

 beneath is glossy green, with the sides of the presternum 

 tinged with orange. The posterior coxse are densely 

 punctate. The femora are orange, with the tips black ; 

 the mesosternal process is as in the male ; the anterior 

 tibiffi are broad and strongly 3-dfintate. The four pos- 

 terior tibiae and tarsi are black, the former slightly tinged 

 with green. The four posterior tibiae are bispinosc 

 between the base and middle, and the apex of each is 

 dilated, especially in the hind pair. The ventral seg- 

 ments of the abdomen are entire, convex, and finely 

 rugulose. 



Genus Asthenoehina. 



In the year 1843 I described and figured two interesting 

 species of beetles belonging to the section Goliathides, 

 forming a distinct genus, to which, in consequence of the 

 unarmed head, I gave the name of Asthenorhina (Arcan. 

 Ent., vol, ii., p. 71, pi. 67, figs. 2 and 3). It is most 

 nearly allied to Tmesorrhina and A])hclorrhina, having 

 the fore legs robust, with thickened femora armed near 

 the tip on the anterior edge with two small acute spines, 

 the clypeus entire, with the fore margin slightly emargi- 

 nate, the maxillffi in the males with the apical lobe slender, 

 and the apex curved and acute at the tip, the mentum 

 deeply and broadly notched, the prothorax with the 

 lateral margins strongly angulated in the middle ; the 

 body in the two specimens represented in the plate (from
