142 RHOPALOCERA MALAYANA. 



Genus CHERSONESIA.* 



Clier.wni-sia, Distant, antt', p. 86. 



This genus is closely allied to Ci/rcstis, from which it iirincipally and structurally difiers by the 

 neuration of the anterior wing, of which the first subcostal nervule only is emitted before the termination 

 of the cell, the second being emitted between the apex of cell and base of third subcostal nervule ; the 

 other neural characters are similar to those of Cinrstis. 



Two species are included in this genus, viz. C. visa, Doubl. & Hew., a species found in 

 Continental India, and C. mhria, Horsf. & Moore, a Javan species, also found in Borneo and in 

 this fauna. Its distribution is probably from Continental India to tbe confines of the Indo- 

 Maiayan region.

Male and Female. Wings above pale ochraceous, crossed by the following fascia3 : — a somewhat 

 curved basal dark ochraceous fascia, margined with fuscous, commencing at about subcostal uervure of 

 anterior wings and terminating slightly beyond submedian uervure of posterior wings ; this is followed by 

 a straighter but more irregular fascia of the same colour, which, commencing about costa of anterior wings, 

 passes the cellular apices of both wings and terminates on posterior wings near centre of abdominal margin ; 

 between these fascise on anterior wings is a short irregular fascia commencing at costa and joining or 

 almost joining the second fascia near median nervure ; a discal curved fuscous fascia, margined with dark 

 ochraceous, followed on anterior wings by a dark ochraceous spot, which precedes a submarginal fascia 

 bounded by fuscous lines commencing beneath apex, the posterior half of which is dark ochraceous, and 

 contains two fuscous spots, and the upper portion is preceded by a dark ochraceous patch also containing 

 a fuscous spot ; an oblique subapical fuscous linear spot and a fuscous submarginal line ; jjosterior wings 

 with a submarginal dark ochraceous fascia, margined by scalloped fuscous lines and containing a series 

 of fuscous linear spots; a submarginal fuscous line preceded by paler and fuscous nebulous shadings. 

 Wings beneath paler than above ; markings similar, but the submarginal fasciae to both wings without the 

 dark outer margins. Body above ochraceous ; thorax marked with some longitudinal fuscous lines, and 

 abdomen with some narrow fuscous annulatious. Body beneath and legs more or less concolorous with 

 wings. 



Exp. wings, 40 to 42 millim.
