Extremely close in outline and coloration to Sten. migratorius and 
Amazonce, Jekel, having nearly the same size and proportions: the 
antennae are even thinner than, in the latter: the thorax is less impressed 
behind, and scarcely clothed with fulvous pile on the disc, with the fulvous 
lateral spot nearer to the middle; also there is no appearance of the fuscous 
spots observed in both of those species; but its principal characters 
are — 1st, its sides are less deeply sinuated (linking pretty well the third 
group to the second), more conically narrowed to the apex than in all the 
species of this group, and, above all, it is the most elongate in proportion 
to its breadth in this second group : the elytra are more narrowed towards 
the apex than in the former, nearly as much so as in the latter, but 
less robust and broadened: the suture and alternate interstices are scarcely 
elevated, and they do not exhibit in the middle the fulvous tessellations 
seen in those species, having only at their base near the shoulder a sub¬ 
quadrate, and behind the middle a transverse, macula, formed of three 
lineolae placed on the alternate interstices, distant from the suture, of 
a fine fulvous pile, together making on both elytra four maculas placed 
quadrangularly; the circumscription of these maculae, with the median 
part of the disc nearly deprived of fulvous nebulosity, is a character peculiar 
to this species, since in all the others the fulvous pile, though more con¬ 
densed at the base and posteriorly, is extended over the middle, especially 
on the suture and the alternate interstices, and distinctly interrupted by 
fuscous or black spots, forming evident tessellations, which are obsolete in 
Sten, mexicanus: the body beneath and the legs are clothed with dark
