184 ON THE SCAKITID^ OF NEW HOLLAND, 



Long. 10| lin., lafc. 4 liu. 

 Hab. New Holland. 



This species differs from G. marginatum in having the thorax 

 truncated in front ; while the base, instead of being slightly 

 emarginate as in the latter, is also truncate. The facial grooves 

 are rather more parallel than is usual in the group. The elytra 

 are margined with green, and are much less distinctly striated 

 than those of G. marginatum. The fore tibiae are bidentate 

 externally without the additional tubercles usual in the group. 



I have no idea what part of the country this insect comes 

 from, — it is in the collection of the late W. S. MacLeay, Esq. 



16. — Carendm surporcatdlum. 



Nigrum nitidum viridi-mai'ginatum, elytris sub lente porcatis 

 porcis subiilissime striatis postice bipunctatis, tibiis anticis 

 extus bidentatis. 

 Long. 11 lin., lat. 4 lin. 

 Hab. Wide Bay and Ipswich. 

 I have long believed this insect to be distinct from G. mar- 

 ginatum, but have hitherto failed to make out a good specific 

 character. It is, in almost every respect, exactly like the last 

 named species, excepting in the sculpture of the elytra, which, in 

 G. marginatum., are marked with very fine striae in indistinct 

 depressions ; whereas in this species the striiB are on indistinct 

 elevations. 



I have a specimen of this insect from Wide Bay, and there 

 are two specimens in the Museum from Ipswich. 



17. Carenum striato-punctatum. 



Nigrum nitidum, thorace postice rotundato, elytris elongatis 



striato-punctatis postice bipunctatis. 

 Long. \0\ lin., lat. 4 lin. 

 Hab. Daly Waters, North Australia. 

 This insect is very distinct from the rest of this group. The 

 facial grooves form nearly a semicircle commencing behind the 

 eyes, converging towards the middle of the face and then 

 diverging. The thorax is rounded away .towards the posterior
