Chorisoneura fuscipennis Hebard 1920

Chorisoneura fuscipennis new species (Plate VI, figure 11.)
The present species is closely related to C. flavipennis Saussure and Zehntner,!" with which it agrees in general size, reddish general coloration and immaculate head. The present species is distinguished by the color of the tegmina, which are less suffused and not as tawny; dark wings, with area of clubbed portions of costal veins buffy; male subgenital plate having the styles more elongate and slender, and in the female by a slight, but distinctly less, reduction in the organs of flight.
These two species form a unit in the genus, which we would call the Flavipennis Group.
