 The second transverse cubital nervure is faint ; the

 cellule. The petiole is smooth and shining ; the sides 

 at the apex depressed ; the rest of it alutaceous ; the

 separated above, the lower part with them smaller and 

 much more closely set together, and at the apex running 

 into striae. The mesonotum closely punctured ; the
