Obs. The female has been described by Mr. Moore as that of his 

 H. cahira (vide supra). 



The male varies considerably in the number of spots in the anterior 

 wings, while the female is almost constant. These variations may most 

 conveniently be exhibited in such a formula as the following, in which the 

 numerals 1, 2, 3, 4, 5, 6, 7, and 8 stand for the semicircular series of eight 

 discal spots seen in typical examples numbered in the order of their succes- 

 sion from before backwards inwards and forwards, the cypher (0) wherever 

 it occurs indicating that that particular spot the place of whose number it 

 occupies is absent, and x representing the submedian additional spot all 

 but invariably present in females only : —

 ately behind and in the same straight line with these, quadrate, the largest 

 of all, being fully double the size of the posterior of the two cellular ones,
