ill both sexes, long and slender, of c5' setaceous and distinctly 

 serrate, of $ but slightly dilated centrally and apicaily acuminate. 

 Notauli wanting, mesonotuin always shagreened and dull; nieta- 

 notuni also usually shngTcened, Mreae wanting with areola at most 

 indicated ; costulfe and spiracular carina always wanting. Scu- 

 telluin convex, rarely pyramidal, always laterally and usually 

 also apicaily carinate. Abdomen elongate and in both sexes 

 subcylindrical, dull and always immaculate testaceous, with 

 hypopygium remote from tei'ebral base. Legs slender and longer 

 than in the Asiatic species, testaceous with the hind ones rarely 

 black- and white- marked ; tarsal claws simple. Wings ample 

 and always flavescent, with stigma testaceous. — Superficially this 

 genus is similar, especially in the shape of the capital vertex, to 

 testaceous species of Hoplismenus, from which the shagreened 

 exoskeleton, lack of conspicuous apophyses, paucity of metanotal 

 carinfe, and very much duller body sufficiently separate it, though 

 the scutellar structure is alike.
