Abstract:

Apparently related to Mesamia but differing from it by a shorter vertex which is broad and slopes from pronotum to a thick margin. The vertex is twice as broad between eyes at base as median length. The face is convexly rounded. The elytra contain many supernumerary veins which are especially prevalent in the claval and costal areas. The first anteapical cell is divided into several small cells by cross veinlets which extend to the posterior border of the second anteapical cell thereby causing the first apical cell to be very small and triangular. There are two cross veins between the first and second sectors, giving a Deltocephaloid appearance.
