half broader at the apex than at the base, subcircularly narrowed at the 
middle of the side ; the median longitudinal ridge is rather wide and high ; 
the lateral ones on the disc are nearer to the sides than to the median, 
strongly indicated in their basal half, especially at the middle, joining the 
inner margin of the eye, where they are obsolete and running obsoletely, 
but evidently, at the same distance from the side to the apex, a character 
more strongly indicated than in any other species. Antennae rather thicker 
than in Sten. fulvitarsis, but their two basal joints are more thickened, and 
the first is rather thicker and longer than the second. 
Thorax hardly as wide as the elytra, less conic than in Sten. fulvitarsis, 
its breadth in front being scarcely more than half of the posterior width ; 
the sides not so deeplp bisinuate, but the posterior lobe is narrowly sub- 
acutely rounded, and the anterior is subangular ; the disc is hardly 
impressed anteriorly, and shallowly depressed posteriorly ; the tomentosity 
is of a fine velvet-like blackish hue, having a figure nearly resembling the 
half of an elongate hexagon, formed of a fulvous-ochraceous tomentosity. 
Elytra much shorter than in Sten. fulvitarsis and all the other species, 
more convex, less depressed anteriorly, with the suture and alternate inter¬ 
stices evidently elevated; clothed with a fine velvet-like blackish pile; the 
disc has a large common patch of a fine fulvous-ochraceous hue, occupying 
all the basal part, except the shoulders,-each side strongly obliquely emar- 
ginate, narrowest between the 3rd and 4th striae, nearly at the middle of 
the length of the elytra, then abruptly transversely dilated, reaching the 
sides of the disc, and slightly truncated behind the dilatation at two-thirds 
of the length of the elytra upon the declivity ; this large patch nearly re¬ 
sembles the outline of a tortoise walking, or a Cassidce. The suture and 
alternate interstices are tessellated with black holosericeous maculae, 
rather distant, but more numerous and extended on the disc than in Sten. 
fulvitarsis. 
Body beneath and legs finely punctate, black, slightly clothed with 
black tomentosity, partly shining and scattered over with extremely fine 
and short grayish pile, hardly changing the uniformity of the black 
ground; tarsi with the two first joints (and the third partly) densely 
clothed with a fine fulvous pile. All the other characters are as in Sten. 
fulvitarsis.
