and third lines, conspicuous white edging along the lines, 

 third line convex anteriorly, concave posteriorly (the line 

 straight or nearly so in floralis) ; a lighter green terminal 

 band very irregular, widest below costal angle (about 5 mm. 

 broad at R 2 ), fading away at anal angle, anteriorly within 

 this border diffuse olive-green spots close to termen. 



$. The olive-green colour of the <J replaced on the upper- 

 side by greenish tawny- olive, on the underside by brighter 

 tawny- olive ; in a crippled 2 the colouring somewhat greener. 

 The white suffusion on the upperside rather more extended 

 than in the g. On the underside a blackish dot close to apex 

 of fore wing corresponds to an olive-green minute dot of the 

 o ; centre of base of hind wing pale green ; on both wings 

 blackish and grey diffuse submarginal scaling which, on fore 

 wing, forms an irregular triangular patch from anal angle

 interrupted before middle. Expanse : g 90 mm., $ 120 mm. 



$. Tenth tergite longer than in floralis, particularly the 

 narrowed apical portion, at apex a minute median incision, no 

 division into two prongs ; margin of tenth sternite slightly 

 incurved in middle. Harpe of clasper as in floralis, but the 

 neck, of which the pair of prongs are the continuation, a little 

 shorter, the prongs slightly variable in length, either the 

 proximal prong the longer or the distal one. Penis -sheath 

 with a large, conical, slightly compressed horizontal tooth. 



Hab. E. Himalayas (Shillong, Khasi Hills, Assam). We 

 have bred this new species in the Khasi Hills near Shillong, 

 at an elevation of about 5,000 feet. Larvae were fairly common, 

 but very local in forests with heavy rainfall, during the rainy 

 season. 



Egg. — Elongate-ovoid, surface smooth and shining, colour
