to those of lambrix, but the third joint is shorter. Sha])e of wings 

 much as in lamhrix, but the costa of fore wing is more arched ; 

 vein 3 well before end of cell ; vein 2 about equidistant from end of 

 cell and base of wing ; vein 5 about equidistant from 4 and 6 ; upper 

 discocellular minute ; vein 1 1 starting about halfway between base 

 of wing and end of cell, almost exactly opposite vein 2, strongly 

 deflected upwards soon after its origin, and touching vein 12 for a 

 short distance. Hind, wing : vein 3 immediately before end of cell ; 

 vein 2 about twice as far from base of wing as from end of cell ; 

 vein 7 shortly before end of cell ; discocellulars oarely traceable : 

 vein o wanting. 



Male with a bristly tuft of hairs, springing from the base of the 

 costa of the hind wing ; there being also a distinct groove on the 

 underside of the fore wing below the subcostal nervure to receive 

 the tuft of hairs when the wings are closed. 



This genus is closely allied to Astictopterus, lamhrix, and Sancus, 

 in the last of which vein 1 1 also touches vein 12 for a short distance ; 

 the only other genus in which at all a similar character obtains is 

 Ci/clopirles, but in this genus veins I 1 and 12 altogether anastomose 

 and run confluent for the rest of their course.

Above dark fuscous. Fore wing with an orange-red fascia crossing 

 the wing at the end of the cell, not reaching either the costal or 

 inner margins. Hind wing without markings. Wings beneath as 

 above ; the fascia on the fore wings being broader than above, and 

 extending from close to the costa up to or slightly beyond the first 

 median branch. 



The fascia on the fore wing varies considerably in extent, especially 

 on the upperside, but on the underside never reaches the submedian 

 and is never diffused along the inner margin as in xanites. 



Expanse 3-3 miliiin. {.vanites expands 41 millim.). 



Occurs throughout liurmali and Malacca, f»nd also in Java. 



This species has hitherto been confused with xanites, Butler; but 

 the latter differs considerably on the underside of the fore wing, 

 the orange fascia extending broadly as far as the outer angle and 

 spreading along the outer half of the inner margin. Xanites a\^\)Q■^\•6 

 to be a rare species, the only specimens I liave seen being the 

 type from Borneo and a single specimen from Malacca ; this is 

 apparently the species figured by Distant ' as (jeminifcr, tiie gem-like 

 spots of the true yemmifer (which is a Kerana) being omitted both 

 from his figure and description. The S])ecie3 figured by Distant as 

 xanites is the species here descril)cd as hector.
