HOMOPTEBA. 



15 



basal half of the costa. Fore wings very slightly clouded with pale brown 

 along the marginal veins; first and second transverse veins very oblique, 

 parted from each other by more than twice the length of each ; third 

 and fourth oppositely oblique, slightly undulating. Length of the body 

 12 lines ; of the wings 36 lines. 



This species much resembles C. Brizo, but may be distinguished by 

 the excavation on the hind border of the thorax, which is peeper and 

 shorter, by its shorter and less attenuated fore wings, and by its stouter and 

 black veins, in whose structure it also differs from C. Brizo.
