6 THE ENTOMOLOGIST. 



Among the specimens from Ventnor are examples with but 

 one or two ocelli, sometimes only the discoidal, on the fore 

 wings, whilst nearly all the ocelli are present on the hind wings. 

 In other specimens from the same locality the inferior pair are 

 without any spots other than the discoidal, and the ocellated 

 character of the primaries is almost normal. Again, the right 

 pair of wings in some few individuals differ from the left pair in 

 their respective number of ocelli. 



Belonging to the obsolete form of aberration are three 

 specimens received from Folkestone, one of which is shown, 

 Plate I., fig. 5. The character of the central series of ocelli in 

 these specimens is curious, and I can only find two examples 

 among the Eastbourne corydon which at all approach it. 



Departure from the normal type, in a direction quite opposite 

 to the last, is shown in an example from Eastbourne (Plate I., 

 fig. 7). This is a good illustration of the increscent type of 

 aberration. As will be seen, the spots on the fore wings are not 

 only very bold, but the basal pair are much enlarged, and exhibit 

 a disposition to geminate, whilst a third basal spot is in evidence 

 between them. In many other specimens from Eastbourne and 

 a few from Ventnor each basal spot has become completely 

 divided, so that these examples have each four distinct basal 

 ocelli ; and one of the Eastbourne specimens has also an 

 additional ocellus, near the costa, on each fore wing, which 

 increases the number of eye-spots of the central series to eight. 



Another Eastbourne specimen (Plate I., fig. 8) represents 

 what I am inclined to consider as probably the incipient stage of 

 a rather micommon aberration, known among collectors of" blues" 

 as the " splashed " or " streaked " var. In well-marked examples 

 of this variety the spots forming the central row are cuneiform. 

 Modifications of this form are, however, of not infrequent 

 occurrence ; thus for instance, among others, is an example from 

 Eastbourne, which has the fifth spot only of tlie central series 

 wedf^e-shaped, and in several specimens from Ventnor the outer 

 ed"e of discoidal spot on fore wings is projected towards the 

 second and third ocelli of central row, whilst these two spots 

 have each a minute dot immediately in front of them. 



Of the confluent form (Plate I., fig. 6) I obtained many 

 examples at Ventnor and a few at Eastbourne. On referring to 

 the figure it will be seen that the lower basal spot and the sixth
