 brevior; dens internarum basalis perbrevis. Articulus antennarum 

 internarum 2dus \mo duplo longior. Pedes antici multo incequi ; 

 manu majore obesd, parce compressd, infra rotundatd, omnino Icevi, 

 partim leviter pubescenti, digitis perbrevibus (manu quadruple bre- 

 vioribus), digito mobili arcuato ; minore oblongd, leviter crinitd, digitis 

 parte manus ante digitos paulo brevioribus. Pedes 2di valde elongati, 

 Stiis sesqui longiores, articulo carpi 2do parce longiore quam \rnus, 

 3tio 4to Stove oblongo, his inter se longitudine asquis. Pedes Stii ktvce 

 leviter criniti, articulo 3tio apicem inferiorem dentigero.
