acute ; outer margin nearly straight ; inner angle rounded, inner margin nearly straight, 

 slightly emarginate in the middle, costal nervure ending opposite to the apex of the 

 discoidal cell ; first sub-costal nervule arising a little nearer to the apex of the cell 

 than to the base of the wing, close to its base anteriorly bowed forward, and almost 

 touching the costal nervure for some little distance ; second sub-costal arising about 

 as far from the first sub-costal as from the origin of the upper discocellular nervule ; 

 third sub-costal short, arising much nearer the apex of the wing than to the apex 

 of the cell ; sub-costal nervure ending at the apex of the wing ; upper discocellular 

 nervule (this is actually the base of the upper discoidal nervule) stout, rather long, 

 strongly outwardly oblique, middle discocellular straight, upright, lower discocellular also 

 straight and upright, slightly longer than the middle discocellular ; second median 

 nervule arising well before the lower end of the cell ; first median arising nearer the 

 lower end of the cell than to the base of the wing, arising about twice as far from 

 the second as the second does from the third ; sub-median nervure slightly sinuous, 

 secondary sexual character consists of a large patch of modified deep black scales 

 occupying nearly the outer half of the cell and extending slightly beyond it into the 

 discoidal interspaces. Hindwing, costa greatly arched at base, thence straight to 

 apex, apex well rounded ; outer margin very nearly straight to the anal lobe ; tails two, 

 short, the anterior one from the termination of the first median nervule rather longer 

 than the posterior one from the termination of the sub-median nervure ; anal lobe 

 small ; abdominal margin sinuous, excavated anterior to the anal lobe ; costal nervure 

 greatly arched at the base, thence straight to the apex of the wing ; first sub-costal 

 nervule arched throughout its length, arising well before the apex of the cell, 

 discocellular nervules of equal length, nearly straight, strongly outwardly oblique, 

 second median nervule arising just before the lower end of the cell, first median arising 

 nearer the lower end of the cell than to the base of the wing, sub-median nervure 

 straight, internal nervure highly sinuous. Antennse about half the length of the costa 

 of the forewiug, with a lengthened, rather slender club. Eyes naked ; palpi naked, 

 porrected forwards, the third joint not rising above the level of the top of the head ; 

 thorax small ; abdomen not nearly reaching to the anal angle of the hindwing. 



Female. Wings somewhat broader than in the male. Forewing with no patch of 

 androconia on the upperside. Hindwing has the outer margin more rounded than in 

 the male. 



Type, C. culta, de Niceville. 



Nearest to the genus Ops, de Niceville, with which it agrees very closely in 

 outline and neuration, but diff"ers from the three species included therein by its smaller 

 size and the character of the " male mark," which in bleached specimens remains 

 unaffected by the bleaching fluid, while in 0. ogyges, de Niceville, the type of the 

 genus Ops, it entirely disappears when bleached ; it also occupies a diff"erent position,
