ABERRATIONS OF EPINEPHELE HYPERANTRUS. 



Fig. 1.

The first specimen is interesting, as it shows considerable 

 bilateral asymmetry in the markings of the hind wings, the left 

 wing being normal and the right curiously blotched ; but the 

 most interesting point seems to me to be the fact that the 

 aberration in the ocellar marks is entirely confined to the black 

 and yellow zones, the central white pupils being in each case 

 quite normal in position and, except in the ocellus next to the 

 anterior margin, of the normal size. This is of course contrary 

 to the general rule enunciated by Bateson and others, that 

 " speaking generally, such reduction commonly occurs by 

 diminution of the diameter of the whole spot ; but if any of its 

 component parts are wanting the centre is the first to disappear, 

 then the next innermost band, and so on."* _ Bateson himself, 

 however, points out that the rule is not a universal one, and in 

 fact in E. liijperantlius, as far as I can judge, from the specimens 

 I have seen in which the ocelli on all the wings are hardly 

 recognisable var. arete, it is the central white pupil that
