160 Mr. G. C. Champion's Revision of the 



(^. Aedeagus : median lobe obliquely bent, rounded at the tip, 

 and with a curved spoon-shaped projection on the ventral aspect 

 at the base ; left lateral lobe short, compressed, obliquely truncate 

 and pointed at the tip, the apex feebly toothed at the upper angle ; 

 right lateral lobe a little longer than the left, compressed, curved, 

 produced at the apex into a stout curved hook, and angularly 

 dilated externally before the tip. Plate VIII, figs. 35, 35a. 



Hab. Nicaragua, Granada and Chontales; Panama, 

 Chiriqui, 



A long series, showing very Uttle variation in colour. 

 The head has a V-shaped mark towards the base, and the 

 prothorax three transversely arranged spots across the 

 middle of the disc (often united into an undulate fascia), 

 infuscate or black, and the elytra are uniformly dilute 

 fuscescent, like the antennae and knees. The median 

 prothoracic sulcus is deep. Gorham omitted to notice 

 the Nicaraguan habitat, though he labelled a specimen 

 from that country, C. sticticus. The form of the aedeagus 

 is characteristic, the median lobe having a spatuliform 

 projection at the base beneath (not visible in our figures), 

 and the lateral lobes are peculiarly formed.

Hab. Panama, Volcan de Chiriqui. 



Described from three females, the male being still 

 unknown. Very like C. submarginatus, but with the 

 third antennal joint relatively shorter, it being only a 

 little longer than the second. The head is small, and the 

 eyes prominent ; the prothorax is opaque, and has a sagitti- 

 form black streak on the disc; the fuscous marginal Une 

 on the elytra does not extend to the base or apex; the 

 palpi, antennae, knees, tibiae, and tarsi are infuscate or 

 black.
