V TACHYPORIDAE. 89 



Antennae short, obviously incrassate towards the extremity; basal 

 two joints about equal, their length double the breadth, 3rd rather 

 shorter, 4th only slightly longer than broad, 5th and 6th shorter and 

 broader than the preceding, joints 7-10 gradually expanded, 9th and 

 10th short and strongly transverse, 11th conical, longer than its pre- 

 decessor. 



With the single exception of the northern C. brevicornis, 2450, we 

 possess no species, as yet, with similarly formed antennae. In 2450 

 tlie 9th antennal joint is just perceptibly larger than the adjacent ones; 

 this is not the case in the present species, which, moreover, is brighter, 

 and has longer and mo)e indistinctly sculptured wing-cases, iVc.

Subdepressed, elongate, slightly nitid, nearly glabrous; head and 

 thorax fusco-rufous, elytra and ]iind-1;()(ly rufo-i)iceous, the terminal 

 segments castaneous, the legs and basal half of the antennae rufo- 

 fulvous, joints 6 to 11 infuscate and opaque. 



Head of about the same length as the thorax, rather narrower, 

 abruptly constricted behind; miiiutely coriaceous and with some fine 

 scattered punctures, interocular foveae ratlier deep, the ocelli situated 

 within these at the base. Eyes not prominent, and not longer than the 

 space between each and the antenna. Labrum testaceous, deeply 

 emarginate in front. Thorax of about equal length and breadth, base 

 and apex truncate, a little wider before the middle than it is elsewhere, 

 its sides very finely margined, slightly rounded anteriorly, nearly 

 straight, though a little narrowed, behind the middle; its sculpture is 

 like that of the head, its median groove hardly reaches the base or 

 apex, along each side of it there is an elongate impression which is 

 broader at the base than in fiont. Scutelluiii large, subtriangular. 

 Elytra nearly twice the length of the thorax, the slioulders are curvedly 

 narrowed, so that the base just exceeds that of the thorax in width, 

 their apices are strongly rounded at the sides but oblique towards the 

 suture; their sculpture is somewhat similar to that of the thorax but 

 is more, though rather indefinitely, longitudinally linear. Hind-body 

 rather longer than the elytra, nearly smooth, segments 2-4 are finely 

 quadripunctate between the middle and sides, the 5th is longer than its 

 predecessor, the 6th is much narrower. 



Tibia(> nearly straight, the anterior very gradually expanded and 

 minutely spinose externally near the apex, the other pairs are fringed 

 with setae. Tarsi with consj^icuous elongate pubescence; their basal 

 joints are a little dilated and, together, shorter than the terminal joint. 



Antennae densely pubescent from their 5th joint onwards, the basal 

 joint is thicker but hardly longer tlian the 3i-d, the 2nd is about as 

 long as the 4th or 5th, tliese last are evidently longer than broad. 



The rather long head, somewhat flattened eyes, peculiar sculpture, 

 and rather large size distinguish this f i om all other species.
