d ?. KSiiiiilar to ^1. nir;/cles. Secoud abdominal segment less grey above. 



AVings, iippcrsidi'. Forewing : more bnffisli, less gre}-, than iu eiirydes. The 



olivc-green costal j)atebes from the base to SC'' larger than in euijdes, the two 

 patches at the end of the cell and distally of it touching each other at the edge 

 of the wing, or nearly so, a distinct blackish brown marginal band of nearly cvca 

 width, tapering in front, limited by a blaclnsh line' which begins at the very extremity 

 of 8C° ; contiguons with this line and standing at its proximal side an olive-greeu, 

 sharply defined band, which is broadest l)etween K' and R-, where it eqnals in 

 breadth the marginal band, while in eur;/cles the olive-green band is much less 



shariily defined, and much wider between R' and W. Hindwing : ajiex less 



pointed than in eiinjdrs and anal angle less prodticed ; the postdiscal black band, 

 which in euri/clcs is distally concave between C and W and therefore anyled at 

 the latter vein, is nearly evenly cnrved ; abdominal margin more grey in ? than 

 in eurycles. 



Uiuler»i(lc, the line outside the cell of both wings and the postdiscal one of 



the hindwing rather heavier than in curijcles. Forewing : discal line closer to 



cell than in the preceding species ; the brown marginal area about 2 mm. broad at 

 SC^, while in eurycles it is narrowed to a point at the end of SC ; the area is mnch 

 more even in width, being not mnch broader between W and R^ than at R^, while 

 in eurycles the area is much broader between R' and R- than at R" ; the posterior 



discal lines vestigial. Hindwing : the postdiscal line not concave between C 



and R2, but slightly convex ; no discocellular bar. 



S. The eighth abdominal sternite has mesially jnst a trace of a lobe (PI. XXII. 

 f. 22). The harpe (PI. XXXI. f. 1) has a submesial process {pm), and the 

 edge md is, also more raised than in eurycles. The penis-sheath (PI. XXX. f. 17) 

 has a longer and non-dentate apical ridge. The tenth sternite (PI. XXIII. f. 6) 

 is truncate, with the angles strongly rounded. The patch of scales on the clasper 

 is very broad (PI. LVIII. f. 32), at least three times as wide as in eurycles.

In the lobe S(!''' of the forewing being less i)rominent than the apical lobe, and 

 iu the marginal band of the underside of the forewing not narrowing to a point at 

 SC'\ euryalus agrees with sfr/yil/s, while eurycles agrees in the same points with 

 sulp/iurea.

^\'illgs, ujipcr^ide. .Forewing less variegated, basal half more distinctly 



l)ui)ilish ; olive j)roximal border of distal marginal band much narrower between 

 Ri and R'. Hindwing : third discal line thinner, more even, less crenate. 



Umler.vde. Forewing : lines SC* — SC", situated halfway between fork and 



apex, converging behind, closer together, mostly merged together before SC; 

 marginal band i)ointed at tip of SC'\ less widened behind R' than iu euryalus, 

 of more even width.
