from Melbourne under the name of ScarapJmia Uowittii. No 

 genus of the name of Scaraphnia has to my knowledge been 

 described, but I am not at all prepared to deny the propriety of 

 forming a geniis for the reception of this species, but any such 

 genus must necessarily include the last named species Speneii 

 and the following one tuherculatuin. 



21. — Carenum tuberculatum, (n. sp.) 



Nigrum, thorace lunulato capite latiori subrugoso dorso 

 canaliculato, elytris ad basin truncatis ad apicem rotun- 

 datis tuberculis quinque striatis marginibusque la(eralibus 

 profunda sulcatis. 



Long 12 lin., lat. 5 lin. 



Hab. Murrumbidgee. 

 The head is broad and somewhat flat ; the frontal impressions 

 are deep and near the centre of the head, curving outwards 

 towards the anterior angles of the head at almost right angles 

 The thorax is much broader than the head, and has the anterior 

 angles much produced ; the posterior angles are rounded, and the 

 base is narrow, rounded, and slightly reflexed ; the dorsal channel 

 is not deeply marked, and there are a number of transverse rugse 

 over the dorsal surface. The elytra are twice the length of the 

 thorax, but scarcely so broad, they are truncated at the base, and 

 rounded towards the apex, and rather flat ; the sculpture may be 

 described as consisting of small flattish tubercles which cover the 

 whole surface pretty closely, they are placed in five tolerably 

 regular rows, a deep lateral groove extends from the humeral 

 angle to within a short distance of the apex ; the under surface of 

 the body is of an uniform shining black ; the legs are not so 

 strong and palmated as in the other species of the group. 



Genus ScARAPHiTES, MacLeay, (Westw. Arc. Ent. 1, p. 157.) 



This genus is easily distinguishable from the last by the great 

 dilatation of the body, and the cylindrical form of the terminal 

 joint of the labial palpi. The species are all rare, and if we may 

 judge of the habits of the whole, by what we know of those 

 of one species, their rarity may be accounted for by the
