386 ON THE CARENIDES (PAM. CARABID.E), No. IV., 



elytra quadripunctate, whereas the type, which is in my posses- 

 sion, has three punctures on each elytron, the posterior puncture 

 being near the apex on the apical declivity. 



Genus Carenidium. 

 Carenidium sapphirinum, Bates. 



A species of Carenidium from the North-west Coast is in the 

 possession of Mr. C. French, which I identify as C. sapphirinum, 

 Bates. The following is a brief description : — 



Upper surface dark violet becoming green on sides of prothorax, 

 elytra and head, also in the frontal sulci; under surface black 

 with bluish metallic tints on guise; prosternum, inflexed margins 

 of elytra, sides of abdomen and legs black. Head large 

 (4-7x7 mm.), upper surface shagreened; labrum emarginate in a 

 regular curve; clypeus sinuate-emarginate behind labrum; inter- 

 mediate angles obtuse, wide at base, projecting lightly. Mandi- 

 bles thick, the left with the tooth in middle thick, short, slightly 

 elevated. Prothorax convex, transverse (6 x 8-7 mm.); sides 

 rounded; border widely reflexed. Elytra oval (14 x 95 mm.), 

 subdepi-essed; base abrupt behind peduncle, lightly emarginate at 

 suture; four or five obliquely placed punctures on each side of 

 base. Length 29, breadth 9-5 mm. 



From C. gagatinum, Macl., and C. superbum, Casteln., two 

 previously described species with impunctate elytra, the colour; 

 the shorter elytra, strongly and evenly rounded on sides; the stout 

 slightly upturned tooth of the left mandible, &c , help to dis- 

 tinguish it. 



Carenidium pyripenne, n.sp. 



$. Robust, convex; head large, labrum and clypeus emarginate, 

 mandibles flattened on upper surface near clypeus; prothorax 

 transverse, base lobate; elytra pyriform; legs light, anterior tibiae 

 bidentate. Black, prothorax and elytra cyaneous towards sides, 

 inflexed margins of elytra and episterna of prosternum cyaneous, 

 antennae reddish-piceous.
