Genus Esthlogena, Thomson. 
Thomson, Systema Cerambyc. p. 107. 
In this genus the body is elongated, subdepressed, and paral- 
lelogram mical or slightly narrowed behind, with the apex of the 
elytra more or less truncated, and sometimes dentate. The 
hairy clothing usual in this group is, in some of the species 
of Esthlogena, short and bristly. The head is small, with no 
depression between the antenniferous tubercles ; the face is short 
and convex, and very slightly prolonged below the eyes. The tho- 
rax is armed on each side with a conical tubercle. The legs are 
moderately long and stout, with subclavate femora and short, 
triangular tarsal joints. The claws are only semidivergent — a 
character which, together with the more elongated body and 
linear elytra, distinguishes this genus from Estola, to which it 
is very closely allied. The antennse, as in Estola, are scarcely 
longer than the body, hairy, with the fourth joint a little longer 
than the third, and the remaining joints becoming gradually and 
slightly shorter. The basal joint is short and thick, and nar- 
rowed at the base.
