ture between the 2nd and 3rd towards the base, a 2nd before the middle, 

 and a 3rd towards the apex, which is slightly emarginate. 



In one specimen the elytra have a slight dull green tinge : it is considerably 

 like what I take to be the H. tardus, 111., and was found at Port St. Elena 

 and Conception.

The 2nd and 3rd joints of the antennae are sometimes piceous, and all the 

 others pale ferruginous. It was abundant at Gorrite and at Maldonado in 

 November. Lieut. Graves.

Ochreus ; oculis, capite, clypeo excepto, scutello subtiisque nigris ; thorace 



angusto ; elytris longissimis, nigro-lineatis reticulatisque. 

 Length 4^, breadth 2 lines. 



Ochreous, shining: head and ei/es black, leaving a semiorbicular ochreous 

 space on the clypeus : thorax short, a little broader than the head, trans- 

 verse-oblong, a line of punctures before and behind near to the margins, 

 a short channel on the disc, sides a little depressed : scutel piceous. Eli/- 

 tra nearly twice as broad as the thorax at the base, and seven times as 

 long, elliptical, apex truncated a little obliquely ; some scattered punc- 

 tures in lines, a short black streak on each side of the scutellum, 3 long 

 ones down the disc, and 2 or 3 oblique ones on the sides ; the spaces 

 between somewhat reticulated with black, leaving a broad marginal space 

 free : underside piceous. 



A male from Port §t. Elena. The narrow thorax and very long elytra de- 

 part so far from the typical form of Colymbetes, that I have little doubt of this 

 being a good genus ; but as I have no specimen to dissect I have not ventured 

 to establish it as such.
