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 Eucnemidge. It appears to approach a little 

 to the genus FKlegon^ but is distinguished from it very easily 

 by the structure of its antennae 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. Epistome 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. Antennae very short, 

 passing distinctly ( J" ) 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 antennae are 

 covered by a very close yellov/ish pubescence. Pronotum 

 nearly twice as broad as long, sufficiently distinctly attenuated 

 in front and very distinctly sinuated on each side above the
