Genus Carterica, Pascoe. 



Pascoe, Trans. Ent. Soc. Lond. iv. (1858) p. 250. 



With this genus commence the more elongated and narrow 

 forms which distinguish the typical Colobotheinse. The elytra 

 are nearly parallelogrammic^ especially in the male sex; in 

 the females slightly dilated a little before the apex. The head 

 is somewhat narrow, and the bases of the antennse rise from 

 distinct antenniferous tubercles. The antennse are greatly 

 elongated, and, from the third joint, very slender — the basal 

 joint being longer than the third, and thickened from the base 

 to near the apex. The prothorax is rather short, much nar- 

 rower at the base than the elytra, and its widest part is at some 

 distance from the base, where it forms, on each side, an obtuse 

 prominence. The humeral angles of the elytra are prominent, 

 and a distinct, but not polished, ridge proceeds from them to- 

 wards the apex ; the surface of the elytra is ribbed, and the apex 

 is truncate, with the outer angle alone prominent and dentiform. 

 The sternums are narrow and plane. The abdomen is slender 

 and tapering, and the terminal segment elongated, especially in 

 the female. In C. cinctipennis the ventral plate of the female is 

 subtubular and truncated at the apex, the dorsal obtusely 

 rounded : in the male the dorsal plate is notched at the apex ; 

 in C. cincticornis the apical segment is shorter and obtuse at the 

 apex. The legs are slender, the basal joint of the tarsi much 

 elongated : the fore tarsi are simple in both sexes.

Mr. Pascoe described this as a new species, believing it, after 

 careful examination, to be distinct from the S. mucronata of 

 Olivier, a species closely resembling it ; but Prof. Gerstaecker, in 

 the Berlin 'Bericht' for 1858 (p. 117), believes the two to be 

 the same, " the description of Olivier being much more indica- 

 tive than his figure.^' It is a generally distributed insect
