In form this species is narrow, with remarkably elongate elytra. The undersurface is 

 constantly chestnut-red, together with the epipleurse of the elytra and prosternum, the legs, 

 antennae, parts of the month, epistome, and narrow lateral rims of the elytra and thorax. 

 The rest of the upper surface is dark, brassy-olivaceous. The thorax is of the same width 

 anteriorly as the elytra, but is much narrowed near the base, nearly as in C. fodince, but the 

 hind angles do not at all project. The elytral interstices are plane ; the punctuation of the 

 striae is strongest in the striae nearest the suture, and the edges of the interstices are there 

 crenulated ; it disappears towards the apex and becomes very faint towards the sides.

Of the flattened form of JB. andrece, B. femoratum, and allies ; elytra scarcely so elongated 

 and rather more ovate than in 23. andrece. Elytral striae sometimes scarcely impressed, the 

 exterior ones much fainter but visible, all punctate and interstices plane or slightly convex. 

 The apical joints of the antennae and penultimate joint of the maxillary palpi are faint ashy- 

 brown. The dusky cruciform mark on the elytra is very variable and is never very dark or 

 clearly denned. As in the allied species, the sutural border is dilated where the transverse 

 fascia joins it. When the lateral margins are dusky, the colour only covers the marginal 



interstice.

Distinguished from all the species of the group known to me by the form of the thorax. 

 This member is moderately elongate and subquadrate, widest near its anterior angles, where 

 its sides are gently rounded, and after this narrowing moderately to its hind angles; but the 

 lateral margin near these latter becomes flattened-out and reflexcd, and the an"-le itself
