34 WOOD AliGUS. 



with a white dot in the centre. The hind wings have a pale buff 

 patch near the centre of the wing, but rather outside it, and a still 

 smaller and faint one on their fore edge : towards the margin they 

 have four buff patches, the fore one with a very small dot, or none 

 at all, the next with a larger one, and the two hinder ones with still 

 larger ones, each with a dot of white in its centre. In some specimens 

 the black prevails over the bufl' more than in others, leaving only a 

 narrow border of the latter colour. 



Underneath, the brown colour of the fore wings is more clouded, 

 the outer corners being much paler, with the eye near the tip shewing 

 through. The hind wings are more varied with waved shades and 

 lines of a darker and a lighter colour, the upper outer corner being 

 paler, and there is a row of five or six white dots, varying in size, 

 near the outer margin, which is darker, and not unfrequently has a 

 tinge of purple, the larger dots being in fact those of the upper side 

 shewing through. 



This is a very variable insect, though preserving on the whole a 

 similarity of appearance. The males are generally smaller and darker 

 in colour than the females, the pale spots on the latter being at the 

 same time larger and more numerous than in the former. 



The figures are from specimens in my own collection.
