COLEOPTERA. 
107 
running from a little above the eyes to the middle ; black or pitchy, dull, 
finely punctulate, except the tip of the median ridge, which is more 
coarsely and distantly punctate and shining; base clothed like the head, 
the remainder glabrous. Antennie proportionally thicker in both sexes; 
2nd joint oblong-conic, evidently longer than the first. 
Thorax less convex, anteriorly, less deeply sinuate at the sides; pos¬ 
terior carina less roundly produced downwards in the middle, less emargi- 
nate near—and less rounded at—its sides, which are subangular, less 
roundly dilated above its supposed posterior lateral angle, leaving there 
the thorax evidently narrower than the elytra, and, as these are much nar¬ 
rower than in 8ten. fulvitarsis, certainly much more angustate than in that 
species; the carina is also more slightly emarginate at the*sides, and less 
widely produced laterally, and, instead of having this second lobe suban¬ 
gular and raised at two-thirds of the length, it is obliquely rounded, 
slightly elevated, terminating nearer to the apex: the median elevation of 
the middle is narrowly continued to the base, the basal central depression 
being divided by it: the pile is much lighter, yellowish fulvous, and 
the spots, instead of being fuscous, are brown, and there is above the 
middle of the disc a transverse row of three spots, the middle one only per¬ 
ceivable in Sten. fulvitarsis: these three spots are sometimes obsoletely 
indicated as well as the two ordinary apical and the intra-lateral line of 
each side. There is, moreover, behind the intra-lateral fuscous line, some¬ 
what above the middle of the side, a punctiform yellow spot wanting in that 
species, but observable in many of the following. 
Scutellum subquadrate, clothed with light fulvous pile. 
Elytra subparallel (the most parallel and elongate of the genus), 
very slightly narrowed behind, much less widened at the base, and much 
more elongate than in Sten. fulvitarsis, less widely impressed on the disc, 
with the lateral depression less obliquely directed inwards, shallower, 
the oblique elevation running from the shoulder separating it from 
the median impression, less indicated and oblique. The ground-clothing 
is brownish, the suture and alternate interstices convex, irregularly clothed 
with yellow pile, condensed on each side of the base within the shoulders 
into a large macula or patch, and behind the middle into an interrupted 
subfulvescent transverse fascia, nebulously circumscribed ; the suture and 
interstices tessellated with rather distant fuscous blackish spots, more indi¬ 
cated on the middle of each elytron, so as to appear as a clouded blackish 
patch.
