 tenniferis crassis, divergentibus. Oculi mediocres, normales.

 quarto tertio breviore, apice lobato-producto et barbato ; se- 

 quentibusbrevibus. J'ro//ioraa;( ^)latitudine longior.utrinque

 basi granulato-cristata, apicibus rotundatis. Pedes validi, 

 antici (^S) longiores ; ^ewom incrassata ; tib'tce anticae sub-

 M. Thomson in his " Essai" places this genus after Leprodera, 

 but in his '* Systema" he puts it with the " Gnomitce." The species 

 briefly described by Hope {penicillata) vras simply referred by 

 him to " Lamia" and seems to have been the type of M. Thomson's 

 genus. One of Mr. Wallace's specimens from Flores has a more 

 uniform colour than the others, all of which appear to have been 

 taken in Borneo and to belong to Olivier's species. Another 

 species, described by myself (Journ. Entom. i. 344), is sufficiently 

 distinguished by, inter alia, the greater comparative length of the 

 third, fourth and fifth joints of the antennae.
