200 Mr. Waticiuiousk on the (jenn.^ C'aloclirouius. 



Rather shorter and broader than the preceding, thorax more 

 transverse, and with the ridge which divides the lateral impres- 

 sion much more directed forwards : I'ostrum almost none, i.e., 

 the space between the antennal pit and the base of the mandible 

 is less than half the diameter of the pit, whilst in C. ruber this 

 space is quite equal to the diameter of the antennal pit. Third 

 joint of the antennaj as long as the first, as long as its greatest 

 width, obliquely truncate at the apex, the fourth joint as long 

 as the two preceding together, a Httle longer than Inroad, very 

 little narrowed at the base, straight at the apex, the fifth to 

 tenth about the same length as the fourth, but gradually 

 diminishing in ■width, scarcely obhque at the apex, their lower 

 anterior angle a httle less than a right angle, eleventh joint 

 much narrower, longer, parallel, acuminate at the apex. Thorax 

 ^ Ijroader than long, a little narrowed in front, disc convex, 

 Avith a rather fine mesial channel, the sides deeply impressed, 

 the usual oblique ridge very much directed forwards, almost 

 parallel with the lateral margin. Elytra very gradually and 

 A^ery little enlarged posteriorly, each with two narrow little 

 I'aised costa=, with an indication of a third.

C. vestitus, n. sp. (PI. II, f. 10). 

 Elongatus, postice paulo ampliatus, niger ; vix cyanescens ; 

 thorace nigro (vel rubro), tenuissime rubro-sericeo ; elytris 

 rufo-testaceis, dense rufo-sericeis, bicostatis, apice nigro. $ 

 Long. 3-4 lin. ^ Eong. 5-6 lin. 



$ Antenna? about f the length of the elytra, moderately 

 liroad in the middle, tapering to the apex. Rostrum extremely 

 short, the space between the antennal pit and the base of the 

 mandible about ^ the diameter of the anteniial ]jit. Thorax 

 lilack, delicately clothed with very fine silky-red pubescence, 

 only visible in certain lights, discoidal channel rather deep, 

 lateral impressions deep and well defined. Scutelhim black. 

 Elytra clothed Avith bright red pubescence ; each elytron with 

 two not very prominent costa? ; the apex black. Under side 

 and legs black, scarcely tinged with blue. Penultimate segment 

 of abdomen emarginate. 



9 Antenna? rather shorter and l)roader than in the male. 

 Rostrum a little more prominent, the space between the antennal 

 pit and the base of the mandible about ^ the diameter of the 

 pit. Thorax reddish-yellow, with the sides and mesial lice 

 l)lack. Each elytron Avith three distinct costa-, the apex broadly 

 black.
