at the summit. Tarsi cylindrical, with the penultimate article 
simple. 
“This genus is extremely remarkable, not only by its facies 
but by its characters, and cannot be confounded with any other 
of the family of Eucnemide. It appears to approach a little 
to the genus Phlegon, but is distinguished from it very easily 
by the structure of its antennz as well as by the penultimate 
article of its tarsi being simple.

“Body oblong-elongate, slightly attenuate in its posterior 
third only, slightly convex, of a reddish brown, somewhat 
opaque, covered above with a yellowish short and dense 
pubescence. Head tolerably distinctly punctate, punctuation 
very close and rugose. Hpistome slightly narrowed at the 
base, distinctly broader than the space between it and the eye, 
strongly excavated transversely in its middle. Forehead 
scarcely visibly depressed in its midst in front, marked in 
some with a small longitudinal keel extending backwards 
to the vertex, and absent in others. Antenne very short, 
passing distinctly (¢) or scarcely (@) the posterior angles of 
the pronotum ; in the ¢ the third article is prolonged in a very 
elongated compressed branch, about twice as long as the first 
two articles united, the remainder similarly prolonged, with 
their branches becoming gradually longer towards the extre- 
mity, the last subequal to the preceding; in the ? the third 
article is simply prolonged into a strong internal tooth, which 
is nearly equal to the rest of the article, the fourth into a 
narrow branch of the length of the first two articles united, 
the remainder similarly prolonged, and gradually becoming a 
little longer towards the apex; in both sexes the antenne are 
covered by a very close yellowish pubescence. Pronotum 
nearly twice as broad as long, sufficiently distinctly attenuated 
in front and very distinctly sinuated on each side above the
