446 Mr. Curtis's Descriptions of 



*69. Trox trisulcatus, Curt. 



Cinerascenti-niger, capite leevi, thorace sulcis 3 latis longitudinalibus, elytris 



striatis : intervallis fasciculatis. 

 Length from 2\ to 3 lines, breadth 1^ to 1^. 



Head and thorax punctured, the former nearly orbicular, with the surface even ; the latter 

 small, the sides ciliated and slightly reflexed, scarcely narrowed before, the posterior 

 angles acute ; a broad but shallow depression down the back, and a long oval one on 

 each side : elytra punctate-striate, with lines of tufts between them, the suture and the 

 alternate spaces raised, with the fascicles larger : anterior tibiae with 2 little teeth out- 

 side, the others rough, with a spine near the middle. 



From Valparaiso. 



It is so very similar in form and size to the T. scaber of Uliger, that I can 

 scarcely believe them to be distinct. I may observe, that in describing- the 

 species of Trox, the clay or reddish colour is not to be depended upon in many 

 cases, as it is extraneous and communicated by the soil which the specimens 

 inhabited. 



Section Scarabjsid.e or Xvlophili. 



*70. HOPLITES QUADRISPINOSUS, Fab. 



Scarabaeus Titornus, Perty in Spix % Martins, Delect, pi. 9. f. 12. 

 Scar. 4-spinosus, Oliv. Entom. vol. i. gen. 3. p. 33. no. 35. pi. 19. f. 179. 

 A male from Rio Janeiro. 



*/l. Scarabaeus Abderus, Sturm, Verz.fur 1826, p. 66. pi. 2. f. 17- S • 



A pair from Gorrite: the female is chestnut-brown, not obscure-black like the male; the 

 head is roughly punctured, with the clypeus acuminated ; the thorax is smooth, shining 

 and sparingly punctured. 



*72. Scarabaeus sylvanus, Fab. 

 A female from Rio Janeiro. 



*73. Scarabaeus cuniculus, Fab. 

 Not uncommon at Valparaiso : all the specimens are densely clothed beneath (excepting the 

 abdomen) with bright fulvous soft hairs, and the margin of the anterior tibia of the 

 females is rather sinuated than toothed.
