138 ON THE SCARITIDyE OF NEW HOLLAND, 



puncture near the clypeus on each side. The thorax is nearly 

 as broad as long-, with the anterior margin truncated, the sides 

 parallel, and the hinder part convex. The elytra have their 

 sides parallel and are slightly emarginated on the basal margin 

 where there are a few small subhumeral punctures ; on each 

 elytron there is an impressed puncture near the shoulder and 

 another near the apex. The fore tibiae are strongly and acutely 

 bidentated externally. 



7. — Carenum oblongum. 



Nigrum nitidum subangustum, thorace elongato antice 



truncato posticc rotundato lateribus parallelis, elytris 



quadri-p un c t atis . 



Long. 8 lin., lat. 2 lin. 



Black and glossy. The head is much the same as that of the 



last described species, excepting that the facial grooves are more 



parallel for the first part of their course, and that the transverse 



connexion between them behind is broad and sKghtly marked. 



The thorax is longer than broa^d, truncated in front, semicircular 



behind, and with parallel sides ; the medial line is crossed 



throughout its whole course by very slightly defined striolte. 



The elytra are almost truncated at the base, with their sides 



parallel until near the apex, whei-e they are rounded ; there is one 



impressed puncture near the humeral angle on each elytron, and 



another not far from the apex. The elytra also present a very 



indistinct appearance of being striated. The fore tibise are 



bidentated. There is but one specimen of this species in the 



collection of Mr. Waterhouse. 



8. — Carenum violaceum. 



Cylindricum violaceum nitidissimum, capite magno, thoracis 



lateribus parallelis, elytris haud punctatis, corpore subtus 



nigro. 



Long. 6| lin., lat. Ij lin. 



This lovely species, which is evidently an approach to the C. 



tinctilatum of Newman, is of a glossy violet colour on the upper 



surface and black on the under. The head is large and as wide 



as the thorax ; the facial grooves are short witb a setigerous piinc-
