a sheen upon it. Both above and helo'w cssculi is very like acacice 

 in colour. 



(2) The white line on the under side hind wings in Swiss 

 specimens (pseudasculi) , as in all typical ilicis of France or else- 

 where, is much more rudely broken up into acute zigzags, the 

 apex of each being sharp and forming an inverted V, and the 

 sharp point of the second, counting from the anal angle, 

 approaching much nearer and with more decision the red 

 chevrons, and on account of its greater irregularity the line is 

 less parallel with the hind margin than in asculi. The dark 

 almost black edging on the inner side of this white line is much 

 stronger in pseudasculi than in cesculi. 



In cesculi from France and Spain the white line is scarcely 

 broken, but runs in regular undulations without sharp angles at 

 apex of the waves, and the second semi-detached curve projecting 

 much less towards the red chevrons than in the other. 



N.B. — I have two beautiful specimens from La Granja which 

 have not a trace of white on either wing * (one of these is 

 suffused with yellow upper side with spots on hind margin of 

 lower wings — var. auronitens) ; the red spots are very firm, 

 regular, and continuous round the whole outer margin, without 

 any black setting. 



(3) The red spots. The colour in Swiss specimens is always 

 an orange-red of different depths. In the true cbscuU I think 

 never, but a brownish-red, often very intense, but without any 

 orange tone whatever. The Swiss insects have this row of 

 red chevrons generally composed of two large or double spots 

 next the anal angle, and three more rapidly diminishing in size 

 as they approach the upper margin, till the last is often little 

 more than a haze. The dark setting of these spots is much 

 broader and blacker than in cesculi. Msculi has three spots 

 much rounder, and hardly appreciably diminishing in size as 

 they ascend, often continuing round the whole outer edge of the 

 wing in French examples, so making seven to eight spots in all. 

 In those from La Granja these red spots are almost entirely 

 absent, and represented only by the three nearest the anal 

 angle, but still maintaining their special form and distinctive 

 colour. 



(4) Of the wing-tails I will only say that Mr. Tylecote (p. 241) 

 describes the difference just as it appears to me. Seitz strangely 

 describes esculi (sic) as a small form with rather a long tail. 

 His plate figures only on the ujpper side, and hence is value- 

 less, and might represent anyone of this group as well as 

 another.
