ARICIA MEDON. 247 



e. ab. inclara, Harr,, "Ent. Rec," xvii., p. 281 (1905); xviii., p. 236 (1906) ; 

 Seitz, " Gross- Schmett.," p. 309 (1909). — Another form I wish to note is a dwarf 

 form. It occurs throughout the range of salmacis and artaxerxes. It expands two- 

 thirds the size of type P. astrarche. Beneath, the wings are of a silvery-grey, like 

 that of Cupido minima. The white ocelli are very small and indistinct, and the 

 row of four near the basal angle is reduced to two. This is of common occurrence, 

 and when at rest is readily distinguished. The name ab. inclara will suffice to 

 determine this (Harrison). 



The four last-named aberrations all tend in the direction of obso- 

 lescence of the underside spotting ; the next, while normal in the 

 markings of the underside has a remarkably strong tendency towards 

 the extreme form of var artaxerxes on the upperside. 



f. ab. subquadripunctata , Harr., "Ent. Rec," xviii., p. 236 (1906). — As in 

 quadripunctaia, but with ocelli with black pupils (Harrison). 



This is another of the forms taken occasionally in Durham with 

 sufficient frequency not to be regarded as merely a casual aberration, 

 for Harrison distinctly states (loc. cit., p. 237) that all such are excluded 

 from the tabulated list he gives. It is a variation all the more 

 remarkable from the fact that, although artaxerxes occurs in the same 

 locality, ab. quadripuncta has never been met with there. This form 

 also occurs occasionally in Lancashire and Westmoreland (Hodgson). 



77. ab. brunnescens, Harr., "Ent. Rec," xviii., p. 236 (1906); Seitz, " Gr.- 

 Schmett.," p. 309 (1909).— Above, fringes brown, otherwise normal ; beneath of a 

 rich warm brown, almost chocolate. The white wedge suffused with brown ; 

 fringes sharply divided into an inward white band, and an outward brown band 

 (Harrison). 



This aberration is very close to var. calida, Bell., in the dark fringe, 

 as well as in the ground colour of the underside and in the suffusion 

 of the white dash on the hindwing. The latter, which is specially 

 mentioned in the original description of calida, is not brought out in 

 the original figure, where the dash, though narrow, is very conspicuous. 

 It is, however, very difficult to judge of the colouring in the figure as 

 it has changed with time past all recognition. This form, however, 

 differs from calida on the upperside, the orange-red spots being neither 

 larger nor brighter than usual. Brunnescens is another of the Durham 

 forms. 



6. ab. fumata, n. ab. ; salmacis, ab., Madd., " Ent. Rec," i., p. 180 (1890). — 

 Underside of all the wings a curious smoky black, with the spots almost obscured 

 (Maddison). 



This aberration is also described as having been taken on the 

 Durham coast. 



1. ab. nigropuncta, n. ab. Artaxerxes, ab., Barr., " Lep. Brit. Isl.," L, p. 75, 

 pk x., fig. 3/. 



The specimen figured by Barrett was taken by Robson, at, or near, 

 Hartlepool, where he had taken another similar aberration. It is the 

 exact reverse of the usual form of artaxerxes, the white on the under- 

 side having disappeared, while the black pupils remain on a coffee- 

 coloured ground. The white streak on the hindwing is absent, and 

 this form seems to be very near to ab. brunnescens, Harr., and still 

 nearer to ab. fumata.
