S4S THE ENTOMOLOGIST. 



(c/. pi. ii., fig. 2, of Mr. South's paper above referred to). 2. The 

 colour approaching that of L. semiargus (fig. 3), of which I have seen 

 none so dark in Ireland. 3. Of a very pale lavender, not mentioned 

 by Mr. South. All these occasional aberrations are found rarely 

 in Ireland with the type. 4. With the extremities of the nervures 

 black, and slightly intruding on the fringes of all wings, thus 

 approaching L. hellargus in being chequered. The most remark- 

 able specimen of this I have ever seen was taken at Killynon, 

 Westmeath, by Miss Eeynell, and the under side is that of var. 

 icarinus, but with all the pupilled spots reduced in size, and 

 several, as well as the basal ones on the fore wing, obsolete ; 

 Cappagh, Co. Waterford, Co. Sligo, and Galway. 5. The mar- 

 ginal line next the fringe is generally broadly marked in Irish 

 specimens, contrasting with those of England in this respect 

 (South). 6. Not unusually there is a series of six black spots, or 

 less, on the margin of the hind wing. I have this form from near 

 the town of Donegal ; at Cappagh, Waterford; and Markree Castle ; 

 and Mr. Kuss takes it occasionally on the other side of Sligo. 

 7. The contour of the hind wings is occasionally very angular at 

 the apex. Varieties of under side : — 1. Ab. icarinus, Scriba, crops 

 up occasionally with type (see note, p. 75, of Mr. South's paper) ; 

 Markree, Castletown, Co. Cork, and elsewhere. The increscent 

 form with confluent spots I have taken on the Continent, but not 

 in Ireland. Other aberrations, as noticed in Mr. South's paper, 

 I need only quote. 2. With white discoidal spot on hind wing 

 unpupilled. 3. With the comet-shaped white streak on hind 

 wings prolonged interiorly toward the discoidal spot (fig. 4), 

 approaching the character developed in L. donzelii, chiron, and 

 damon ; Donegal and Markree. 4. With the outer margins 

 external to the orange peacock-eye shaped ocelli pure white, a 

 character developed in its extreme form in L. hylas, Esp. 

 {dorylas, Hiib.) ; Mr. South records this character as occurring 

 also in some Scotch examples. 5. In some specimens the 

 ground is of a smooth pearly grey, a very general character in 

 Swiss examples, but occasionally a warm rusty brown is shown 

 (fig. 4) . The female offers the most conspicuous divergence from 

 the normal English and Continental type, in which the basal half 

 only is dusted with blue scales (fig. 8), the brown of the upper 

 Bide being widely replaced by a violet or occasionally wholly by the 

 bright blue of L. hellargus. These forms are not uncommon in 

 Ireland, in Galway, Sligo, Donegal, Antrim, Down, Westmeath, 

 Waterford, &c., and are accompanied by a series (often almost 

 confluent) of very bright orange peacock-eye markings on the 

 outer margins of all wings, so that some specimens (if not too 

 b-illiant) would pass muster as the var, ceronus of L. hellargus 

 (fig. 12) ; another most interesting testimony to the genetic 

 affinities of this species. This var. ceronus of icarus occurs in 

 some abundance at Ballynahinch, Connemara, and at Ardrahan
