apicem versus tenuiores, nigrae: corpus subtus pedesque nigri,

More narrow and elongate than its congeners, and, moreover, 
notable by its pale fulvous colour, the apex of the elytra only 
and the medial dise of the thorax alone being black. 
I have two examples of the species before me, which differ in 
no respect from each other; one from Buenos Ayres, from 
M. Chevrolat, and the other from South Brazil, from M. Reiche’s 
Collection.

The thorax of this species resembles that of S. frenata (ante, p. 
264); but the elytra abundantly differ. The general pattern is 
the same, but in the species before us there is a flavous fascia ona 
black ground ; in S. frenata the fascia is black and the elytra are 
flavous.
