Hindwings light fuscous, or whitish-fuscous, or whitish; terminally darkened; without a clear discal mark; without transverse lines; exhibiting vein 5. Vein 5 of the hindwings strong (distally); arising nearer to vein 6 than to vein 4. Thorax crested (front and rear). Middle tibiae with spines. Posterior tibiae with spines. Abdomen not crested.
