aud middle of pro- aud of anterior ]iortioa of mesosternum bulF, middle of abdomeu 

 ochraceous bnff ; middle and hinder legs : femora black, with white scaling, tibiae 

 and tarsi dark clay colonr. 



d. Wi/iffs above purplish black, with a slight brown tint. Forewing : with 



an obliijue series of postdiscal, tawny ochraceous, patches of variable size from SO' 

 to internal margin, last spot buff colour, a spot before SC= sometimes vestigial ; or 



these spots all absent, bnt occasionally the last one or two indicated. Hindwing: 



postdiscal interspaces filled up by pale blue patches which are fused with the 

 creamy white or yellowish admarginal interspaces to a broad baud, which is divided 

 by the thin black veins and includes the black postdisco-submarginal, rounded spots 

 with bluish white centres, proximal edge of band convex between veins, bine scaling 

 C — SC'' obsolete in most individuals, admarginal black line continuous, heavy. 



Underside chestnut, the glossy parts somewhat olivaceous, bars heavy, rather 

 variable in size and position, mostly edged with greenish olive, but if the interspaces 

 between the bars are pale ochre yellow, the respective bars are edged with white; 

 submedian interspaces of fore- and hindwing partly pale ochre yellow in some 



specimens. Forewing : discal interspaces sometimes with pale yellow patches at 



the outer side of the median bars ; discal bars halfmoon-shaped, postdiscal ones 

 also luniform bnt much less conspicuous, the postdiscal interspaces (between these 

 bars) pale yellow, this colour mostly extended between M- and SiP to near edge of 

 wing, including two black spots, the upper yellow postdiscal interspaces sometimes 



obsolete; white submarginal scaling forming small patches between veins. 



Hindwing: discal and postdiscal black luniform bars strongly arched, the postdiscal 

 halfmoon-shaped interspaces bright chestnut, mostly somewhat yellowish at discal 

 bars ; postdisco-submarginal, glossy grey, patches SC* — M' about equal in size, 

 except patch R^— M' which is larger, patch C— SC very small ; submarginal bars, 

 which form the outer portions of these patches, black ; white submarginal dots 

 within patches all present ; admarginal interspaces pale ochre yellow, the upper 

 four larger than the glossy grey postdisco-submarginal patches ; admarginal line 

 continuous, blackish chestnut ; upper tail, 5i to 8 mm. long, second a short tooth. 



? . Wtngs ahore. Forewing : postdiscal pale ochre yellow patches very large, 



the band of patches either complete, often with the discal interspaces SC* — R^ also 

 pale ochre yellow, or incomplete, the band extending from internal margin to M' 



and then fading away. Hindwing as in S , but the postdisco-submarginal black 



patches much larger, the blue postdiscal interspaces only partly joined along veins 

 to the pale admarginal ones. 



Undermde nearly as in c?, except that the submedian, discal and postdiscal 

 interspaces are more extended yellow, hence the underside appearing more 

 variegated ; median bars of forewing closer to the discal ones than in most t?, 

 bars R^ — M' sometimes touching one another ; upper tail broad, 6^ to mm. long, 

 second a blunt tooth. 



Length of forewing : c?, 42— 52 mm. 

 „ ,, ? , 55 — 65 mm. 



According to the development of the band on the forewing above one can 

 separate the individuals into two groups the names of which are : 



a. Ch. eurialus ab. eurialus (syn. : abruptus P'rahst., I.e.). 

 Band absent or only marked behind in i^, abbreviated in front in ?.
