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 submedian 

 nervure ; anal lobe small ; ahdominal margin sinuous, exca,vated 

 anterior to the anal lobe ; costal nervure greatly arched at the base, 

 thence straight to the apes of the wiag ; first subcostal nervule arched 

 throughout its length, arising well before the apes of the cell ; disco- 

 cellular 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 

 the base of the wing ; suhmedian nervure straight ; internal nervure 

 highly sinuous. Antennce. about half the length of the costa of the 

 forewing, 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. cidta, de Niceville. 



Nearest to the genus Ojjs.^ de Niceville,* with which it agrees very 

 closely in outline and neuration, but differs 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. ogi/ges, de Niceville, the type of the genus 

 Ops, it entirely disappears when bleached ; it also occupies a different 

 position, as it does not extend anteriorly or posteriorly beyond the 

 cell, being strictly bounded in those directions by the subcostal and 

 median nervures.
