The next genus is C'olanii. with which I unite Epicyilas B. Baker. Mr. 

 Bethune Baker differentiates this from Cotana because vein 10 of forewing is 

 not stalked, but I consider this character alone not of sufficient importance to 

 separate the two genera. It must have struck everjone as strange that of 

 Cotana there were only ?$ while of the genus Nerviconipressa only <JcJ existed ; 

 the truth is that they are sexes having exactly the same nenration. Here we 

 have many species and subspecies.
