RHOPALOCERA iMALAYANA. 139 



very prominent and dark fasciae on disk, and a narrower and paler one near base of both wings. Body and 

 legs moi-e or less concolorous with wings. 



Exp. wings, ^ & ? 55 to GO millini. 



Hab. — Continental India ; North-Eastern Provinces (coll. Dist.) — Malay Peninsula ; Penang (coll. 

 Moore) : Province Wellesley (colls. Dist. & Sailer) ; ]\Ialacea (Pinwill — Erit. ]\Ius.) 



This species is easily distinguishable from the last by tho much less angulatiou of the 

 anterior wings, the different and zigzag markings, and its generally larger size. 



According to the specimens now before me, the subapical white spot to the anterior wings 

 is more prominent in the female than in the male sex. 



Ergolis isaeus. 



Kiyolis Isiiiis, Wallace, Trans. Eat. Soc. 1809, p. 388, u. 4. 



As I do not know this insect, I can merely give Mr. Wallace's description : — 



" Outline of wings nearly even, with an angular lube on the upper wings, waved strife somewhat as in 

 E. Coryta* but disposed in pairs, no white spot near the apex ; on the hind wings a series of distinct 

 sublunulate ring markings, each enclosing an obscure reddish spot. Beneath, upper wings dusky, the disc 

 reddish brown, the borders pale, a dusky streak parallel to the outer margin ; lower wings pale bro-RTi, the 

 markings as above, but the lunulate ring spots smaller, the outer border ashy brown." 



" The female is like the male, but paler, especially beneath." 



"Sizeof £. Conjtar 



"Hab. — Malay Peninsula; ' Singapore.' — ' Sumatra' (coll. Wall., type)." 



"This species has probably been confounded with E. Coryta, from which the even outline of the 

 wings and the absence of the white spots at once distinguish it." 



Genus CYKESTIS. 



Cyrestis, Boisduval, Voy. Astrol. Lep. p. 117 (1882) ; Westw. Geo. Diurn. Lep. p. 260 (1850). 



Wings pale and delicate ; anterior wings subtriangular, the costal margin strongly arched, the outer 

 margin irregular, waved, sinuated, or slightly convex ; inner margin slightly rounded, convex at base, and 

 slightly concave beyond the middle. Costal nervure extending to about the middle of the costal margin . 

 first and second subcostal nervules emitted before the end of cell (the second being very near its extremity), 

 second much longer than first ; third emitted about two-thirds beyond end of cell ; fourth and fifth widely 

 divergent, and bifurcating about midway between base of the third and apex. Lower disco-cellular uervule 

 very slender, suberect, slightly curved inwardly, and indistinctly closing cell, which thus forms a triangle. 

 Fii-st median nervule strongly arched, and with an apparently common origin with the second. Posterior 

 wings elongated, sometimes somewhat hexagonal ; the costal margin nearly straight, becoming rounded 

 and convex towards apical angle, or as in typical species coucavely emarginate at that spot : outer margin 

 more or less sinuated to extremity of first median uervule, where it is narrowly prolonged in caudate 

 elongation ; from thence to anal angle it is somewhat truncate, the anal angle being spatulately produced ; 

 the abdominal margin more or less concavely emarginate before the anal angle. Precostal nervure slender, 

 curved outwardly ; costal nervure obliciuely erect at base, and then extending to near apex ; lower disco- 

 cellular nervule aborted, in some specimens very faintly visible. Body small and slender. Antenna; 

 very slender, terminated by an elongated and gradually formed slender club. Palpi long and strongly 

 porrected. 



'•' As iireviously pointed out, this is a synonym oi E. ariadne.
