NO. II.— SIX NEW SPECIES OF CARABID^. 



By Thomas G. Sloane. 



I lately received from Mr. C. French, Government Ento- 

 mologist of Victoria, six species of Carabidse belonging to the 

 tribe Carenides ; of these four came from the Fowler's Bay 

 district of South Australia, two being new species, which I have 

 named Carenum vicinuin, and C. lepidum ; the other two are 

 C. rugatum, Blackburn, and G. (Chariscapterus) opulens, Sloane ; 

 of the latter there are two specimens, one of which has the elytra 

 of a beautiful coppery purple. The two remaining species are 

 from the McDonnell Ranges, in the centre of the continent, and 

 are a new species of Euryscaphus (E. titanus), and a new 

 Carenmn (C. habitans) very distinct from anything I have 

 previously seen. 



Euryscaphus titanus, n.sp. 



Black, shining. Head large, subquadrate (9J x 12J"^ mm.) ; 

 thick and heavy, the frontal sulci short, connected behind by a 

 faint curv^ed impression, parallel towards the front, then turning 

 outwards in a broad curve ; clypeus sloping backward from the 

 labrum, with the usual setigerous puncture on each side in front 

 of the out-turned frontal sulci ; mandibles large, smooth towards 

 the apex, transversely striate on the large internal teeth ; eyes 

 prominent, a short blunt tooth-like process projecting forwards 

 and downwards below them ; mentum short, lobes rounded 

 externally to the inner point, the inner side almost square, 

 the median tooth broad, triangular, keeled, with broad reflexed 

 margins (epilobes), two deep fove?e on each side of the base 



* This is the width without the eyes ; the same remark applies to the 

 measurements of the head in the other species described in this paper.
