regularly convex, not only of any of the species of this group, but also of 
the whole genus; their fulvous mixture (as well as that of the thorax) 
is lighter than in the three preceding species, and the large nebulous dark 
patch formed with the blackish tessellations at the middle of the elytra is 
much better indicated and circumscribed than in the preceding, the flaves- 
centpile of the alternate interstices being nearly wanting in that part: the 
tarsi have their first joint only densely covered with a yellow pile, and the 
second and third are nearly denudate; the terminal is slightly scattered 
over with thin short yellowish hairs, showing the ground. 
It varies also in being sometimes not more than one-half the ordinary 
size.

This interesting species is one of the most distinct of the second group. 
Its elytra are as parallel as, though much shorter than, those of Sten. 
longulus , and were it not for its habitat I would have placed it immediately 
after that species. Nevertheless, by the slight depression of the elytra at 
the suture and sides, especially posteriorly, where these organs are regularly 
convex, it has a somewhat natural connection with Sten. tessellatus. 
The only specimen I know is nearly as broad as Sten. longulus , 
but much shorter, the parallelism of its elytra is still more evident, but 
extends only to two-thirds of the length, and afterwards the sides are more 
abruptly roundly narrowed towards the apex than in any of the other spe¬ 
cies. The posterior declivity of these organs is more perpendicular than 
in its allies : the thorax, nearly shaped as in Sten. longulus , is less trans¬ 
verse, or rather, more elongate, since it is not narrower in proportion to the
