364 MISCELLANEA ENTOMOLOGICA, 



very coarsely punctured, and there is a small deep fovea near 

 each posterior angle. The female has no excavation in the 

 thorax, and the vertex is furnished with a short bifid horn. 



BOLBOCERAS CARPENTARIiE. 

 Long. 8-2 lin. 



Piceo-rufum nitidum, capite antice cornuto — cornu subbrevi 

 subacuto antice basi bisinuatim carinato, thorace vix retuso 

 bicoi'nuto punctate ad latera foveolato basi laevi, elytris 

 striato-punctatis, tibiis anticis estus 5 dentatis. 

 Hab. Sweer's Island. 

 I have only seen the male of this species. The horn on the 

 head is shorter than in the last. The thorax is scarcely exca- 

 vated but has a plane surface in front, with a short somewhat 

 porrect horn on each side. The base, with the exception of the 

 median line, is smooth, the remainder rugosely punctate and 

 deeply foveated on each side. 



BOLBOCERAS DENTICOLLE. 

 Long. 9| lin. 



Piceo-rufum nitidum, capite punctate apice cornuto ad latera 



utrinque bidentato, thorace subretuso apice subobtuse 



tuberculato-producto medio fortiter bicornuto — cornubus 



divergentibus — omnino parce punctate lateribus serratis, 



elytris fortiter striato-punctatis, tibiis anticis extus 6 



dentatis. 



Hab. Victoria River, or Peak Downs. 



The male of this insect has a short nearly upright horn at the 



very extremity of the head, with two teeth on each side, one 



large and triangular near the eyes, the other smaller between 



that and the clypeus. The thorax has an obtusely pointed 



tubercle at the apex with a somewhat excavated space behind, 



which is surmounted by two strong divergent horns, the sides are 



dentated. The elytra are strongly striato-punctate. I have not 



seen the female. This species is in the Museum collection, and 



was brought from one of the above named localities by the 



Expedition which, under the command of the late Sir Thomas 



Mitchell, first penetrated to the Victoria river.
