NOTES ON THE GENUS LYC^NA. 5 



or whitish grey, and the hind wings light brown or greyish 

 brown ; whilst in the latter the fore wings are light brown, and 

 the hind wings a slightly darker shade of the same colour. The 

 spots in both sexes are the same in number, and similarly 

 disposed in their respective types. As a rule, in descriptions 

 of species of Lyccena the basal, discoidal, and central series of 

 spots only are referred to as ocelli ; but, though smaller, those 

 on the hind margins of the wings are of exactly the same 

 character, i. e., they are white disks with black centres ; and in 

 the following remarks they will be considered as ocelli also. 

 The normal arrangement of the ocelli on the under side of 

 corydon is as follows : — Fore wing : Two basal, one discoidal, 

 and seven external to this, forming a more or less curved row ; 

 beyond these again are seven on the hind margin, each preceded 

 by a blackish crescent. As the last two ocelli of this series are 

 always small and sometimes faint the apparent number is five 

 only. Hind wing : Four basal, one discoidal, and beyond this 

 seven or — as the last of the series is often a double one — eight, 

 forming a somewhat irregular curve ; on the hind margins are 

 six ocelli, bordered internally with orange, black and white 

 crescents, or triangular marks ; a white triangular dash has its 

 base on the fourth, sometimes extending to third, hind marginal 

 ocellus, and its apex between the fourth and sixth ocelli of 

 central series. All the ocelli, both as regards shape and size, as 

 well as position, vary exceedingly; but it is unnecessary to enter 

 into any lengthy disquisition upon the whole scheme of deviation 

 in this or that direction from the normal type. At the same time 

 there are three leading types of variation, which deserve full 

 consideration. These for convenience may be styled the obsolete, 

 increscent, and confluent phases of under side aberration. 



Figure 1, Plate I., represents an extreme example of the 

 obsolete type from Eastbourne. Between it and the normal type 

 are many individuals from the same locality; showing various 

 modifications as regards number of ocelli, some of which are 

 represented by figs. 2, -'3, 4, PI. I. In what I should say is the 

 initial stage of this form of aberration one of the basal ocelli of 

 fore wings, generally the lower, is absent; next both basal ocelli 

 have vanished ; then the first four of the central series disappear 

 one by one ; and connected with this last is usually a decrease in 

 the number of ocelli on hind wings.
