Forewing, vein 12 short, reaching the costa before the end of the cell, 11 from 

 the middle of the cell, 7 from before the end, 10 from half-way between 11 and 7, 

 9 out of 7 from beyond the middle, variable in length, but generally short, 8 absent ; 

 upper discoidal short, straight, outwardly oblique, lower variable, twice as long to four 

 times as long as the upper, straight generally, but not always, outwardly oblique, 

 vein 6 from upper end of cell, 5 from upper discoidal, its base rather close to the base 

 of 6, 4 from lower end, 3 from a short distance before lower end, 2 from one-third 

 before end, bent downwards and curved, median nervure bent upwards fiom the origin 

 of vein 2, sub-median nervure sometimes straight, often waved. Costa variable, 

 nearly straight, sometimes arched more or less, in some species more or less depressed 

 towards the apex, apex angular, sometimes acute, outer margin variable, straight in 

 some species, evenly convex in others, and sometimes concave below the apex, then 

 convex, hinder margin generally (not always) hollowed in the centre, hinder angle 

 more or less rounded. Hindwing with vein 8 generally well arched, 7 emitted some 

 distance before upper end of cell, well arched, upper discocellular shorter than the 

 lower, rather concave and outwardly oblique, lower erect, or somewhat oblique 

 inwardly, occasionally straight, rarely concave ; vein 3 from just before lower end of 

 cell, internal vein recurved, wing generally ample, in some species without a tail, but 

 generally with a tail at the end of vein 2, which is sometimes little more than a tooth, 

 but varies considerably and is often long, sometimes there is a second very short 

 tooth-like projection at the end of vein 3, and occasionally a third very short one at 

 the end of vein 4. Costa evenly arched, sometimes waved, sometimes straight, apex 

 and outer margin evenly rounded, abdominal margin variable, straight, emarginate or 

 curved. Palpi rather long, porrect ; body more or less robust. Genitalia follow one 

 pattern very closely, having the tegumen composed of an ample hood with strong 

 muscular hooks straightish, i.e. not elbowed, the clasps decidedly small, and the penis 

 of a medium size. 



Type, phryxus, Boisduval = helius, Cramer, from Amboina.
