Genus CHEBSONESIA.* 



t % t'stutrnot Durtaoflij tmh , p. 9fls 



This genua ia closely allied to Cyreath, from which it principally and structurally differs by the 

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

 of the cell, the second being emitted between the apes of cell and base of third subeustal nervule; the 

 other neural characters are similar to those of CyreUit, 



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

 Continental Lidia, and C* ra//.na, Horsf. & Moore, a Javan species, also found in Borneo and in 

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

 Malayan region.

Male and I 1 em ale. Wings above pale ochraceous, crossed by the following fasciae ; — a somewhat 

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

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

 a straighter but more irregular faBcia of the same colour, which, commencing about eoBta of anterior wings, 

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

 between these fascia: 1 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 submargmal fascia 

 bounded by fuscous lines commencing beneath apes, 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 Bpot ; an oblique subapical fuscous linear spot anil a fuscous submarginal line ; posterior wings 

 with a subniarghml 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 lwnunth r than above; marking similar, but Ihc- siubmsnyiiuil fascia. 1 to both wiuys withoul the 1 

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

 abdomen with some narrow fuscous annulations* Body beneath and legs more or less concolorous with 

 wings.
