NEW AXD LITTLE-KNOWN BUTTERFLIES. 141 



Linn. Soc. Lond., Zoology, vol. xxv, p. 387 (1896), reduces C. att'ila 

 to the rank of a '* var." of C. jupiter, but it is really more distinct from 

 that species than is C /;^2a?jz«. As these insular local races appear to 

 be constant where each occurs, they are in my opinion worthy of full 

 specific rank. 



Described from three males and two females received from Herr 

 Heinrich Kiihn, after whom I had intended to name it had not Mr. 

 Rothschild published his description first from specimens from Kei 

 Toeal and Great Kei. 



Family LYC.EXIDiE. 

 11. Gerydus longeana, n. sp., pi. Z, figs. 15, (J ; IG, $. 



Habitat : Upper Burma. 



Expanse : <J, 1-4: to 1-8 ; 9, 1-2 to 1'6 inches. 



Description : Male. Upperside, forewmg dull brown at the basej 

 the outer half dull fuscous ; a curved discal whitish band divided into 

 five parts by the dark veins, the anterior Dorcions divided by the 

 third median and lower discoidal nervules elongated, the two posterior 

 portions placed behind the outer posterior end of the portion anterior 

 to them small and nearly quadrate ; base of the third median nervule 

 swollen and bare of scales. Hindwing rounded, varying in colour, 

 sometimes entirely pale bro\^^^, with the costa broadly dull fuscous, 

 sometimes the posterior two-thirds stone-colour. Underside, both 

 loings ochreous-brown, with the annular markings as in specimens of 

 G. hoisduvali, Moore, from Sikkim. Forewing with a broad cun-ed discal 

 white band, of equal width throughout, extending from the upper 

 discoidal nervule to the inner margin, its inner and outer edges 

 irregular. Hindwing with a transverse discal dark brown fascia ; 

 the submarginal series of black dots not very conspicuous. Female. 

 Upperside, both icings creamv-white. Forewing with the apex broadlv, 

 the outer margin decreasingly, dull fuscous, sometimes with a small 

 black patch in the middle of the wing placed on the bases of the first and 

 second median nervules. Hindwing slightly angled at the termination 

 of the third median nervule, with the costa broadly pale fuscous ; this 

 fascous area is larger in those specimens with the discal black patch in 

 the forewing than in those without it. Underside, both loings very similar 

 to those of the male, but the ground-colour is more ochreous and much 

 paler.
