Patria: Brasilia, Dorn. Dupont. 
This species is rather smaller than the largest specimens of Sten.ful- 
vitarsis , but it is much narrower, being the most elongate and parallel of 
the genus. The thorax is less shortened, less dilated at the sides pos¬ 
teriorly, the central longitudinal elevation more indicated, and descending 
nearer to the base; it has three fuscous spots placed in a transverse row 
above the middle, and the elytra are much more elongate and convex and 
subparallel, independently of the different colour. 
Head subperpendicular when at rest, longer than wide, a little shorter 
behind the eyes than between them, convex (in Sten. fulvitarsis it is nearly 
flat), subimpunctate, with a short thin longitudinal canal on the middle of 
the vertex, leaving an interruption between it and the rostral ridge which 
runs behind the forehead, covered with a light fulvous pubescence, 
condensed in a yellowish hue round the eyes and in the posterior canal. 
Eyes generally brown, sometimes pitchy, ovate, subtruncate anteriorly, 
placed longitudinally subobliquely, narrowing the forehead towards the 
rostrum, slightly convex. Rostrum nearly one-half longer than the head, 
and much narrower at the base, proportionally shorter and narrower than 
in Sten. fulvitarsis , with the sides straight from the base to nearly 
one-fourth of the length, then obliquely dilated, and still more abruptly so 
towards the apex, where it is one-half wider and nearly as broad as the 
head at its base ; apex sinuately truncate, with its sides shortly obliquely 
truncated ; flat, especially near the tip, where it is shallowly impressed, 
having a raised glossy longitudinal ridge along the middle, somewhat. 
widened and depressed at the apex, and two other short thin and lower 
ridges, one at each side of the median ridge, nearer to it than to the sides,
