lUIOPALOCERA MALAY AN A. 255 



classed as male aud female S. nedijmuiid. The only reason why that course is not followed 

 here, is owing to the fact, that the female .S. chitm has a more curved upper tail-like appendage 

 than the male S. nedjimoml, aud the ground colour beneath being somewhat diverse. "When 

 the insects are bred the above supposition may not improbably prove correct. 



Genus HYPOLYCENA.

 (1884). 



Anterior wings siiljtriangular, costal margin arched at base, the apex subacute, outer margin slightly 

 convex, inner margin slightly concave. Costal uervure terminating nearly opposite end of cell; lirst 

 subcostal uervule emitted a little beyond middle of cell, second a little closer to first than third, the last of 

 ■which is emitted a little before end of cell, which reaches to about the middle of wing ; first and second 

 median nervules emitted close together at end of cell. Posterior wings subovate, the costal margin at 

 a short distance from base oblique to apex, which is rounded, outer margin oblique, slightly waved and 

 produced at second median nervule and with two slender tail-like appendages, one at apex of third median 

 nervule aud the other at apex of submedian uervure ; abdominal margin somewhat concavely cleft near 

 anal angle, which is moderately lobular. Costal nervure strongly arched at base and reaching apex of 

 wing, first subcostal nervule emitted at about one-third before the end of cell ; first and second median 

 nervules with an apparently common origin at end of cell. Palpi porrect, second joint stout, but scarcely 

 extending before the eyes, third joint slender, very long, of nearly equal length to second ; antenme 

 moderately long, with a gradually thickened but well-formed apical club. 



This is a widely distributed genus, and extends from Continental India through the Malay 

 Peninsula, and throughout the Malayan Archipelago. It is also probably common to Tropical 

 Africa, a number of species found there being apparently congeneric.

Male. "Wings above dark indigo-blue ; anterior wings with a discal patch of blackish scales at end of 

 cell ; posterior wings with a whitish submarginal line extending from second median nervule to anal angle ; 

 fringe greyish ; tail-like appendages with their margins pale greyish ; a dark spot at anal angle margined 

 with white. AVings beneath dark grey, tinged with greenish. Anterior wings with two brown disco- 

 cellular lines at end of cell, followed by a narrow dark brown fascia, margined with greyish, commencing 

 near costa and terminating at the submedian nervm-e, aud a paler brownish submarginal fascia, between 

 which and the outer margin the colour is more or less tinged with brownish ; fringe brown, tipped
