sides of the posterior carina; the elytra more rounded at the base, more 
convex, broader proportionally, and more abruptly and obtusely rounded 
to the apex. All these characters, if they were not evidently such in the 
male, compared with the female of Sten. varipes , would be sexual (that is 
feminine) in the same species ; they however exist in these proportions in 
each sex of both : I, therefore, think the present insect to be specifically 
distinct.

This species is as nearly allied to Sten. varipes , Sch., and Sten. verti¬ 
cals , Jekel, as the species of the second group between them ; it is half the 
size of Sten. varipes , and is the most minute of the genus: the thorax is 
longer in proportion to the elytra, its two longitudinal canaliform impres¬ 
sions are shallower, the lateral angle of the posterior carina is more angu¬ 
lar, and the sides, yet straighter, are more obliquely narrowed to the apex: 
the elytra are, in proportion 4o the thorax, shorter, they are less flattened 
along the suture, evidently more narrowed towards the apex; their light 
tessellations are whitish, their disc is more mixed with white : the body 
beneath and legs have their light mixture whiter, and the first joint of the 
tarsi is of a milk-white hue: the rostrum is also less widened to the apex 
than in these two species. 
Of this Lilliputian Stenocerus I have seen only one male specimen. 
Its antenna are much longer than in all the males of the other species*
