Capt. P. P. Kine’s South American Coleoptera. 195 
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, Ill., and was found at Port St. Elena 
and Conception.

The 2nd and 3rd joints of the antennz are sometimes piceous, and all the 
others pale ferruginous. It was abundant at Gorrite and at Maldonado in 
November. Lieut. Graves.

Tas. XV. Fig. E. 
Ochreus; oculis, capite, clypeo excepto, scutello subtüsque nigris; thorace 
angusto ; elytris longissimis, nigro-lineatis reticulatisque. 
Length 41, breadth 2 lines. n 
Ochreous, shining: head and eyes blaek, leaving a semiorbicular ochreous 
space on the clypeus: korax 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. Ely- 
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 St. 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.
