n D. a. argenthona, longer than broad, defined by whitish; 

 bhick marginal border broader, especially towards torn us. 



? . Above. — Ground-colour dead-white ; baso o£ both 

 wings irrorated with black and yellow. Fore wing : differs 

 from forma seminfgm, Friihst., in discocellular white spot being 

 very small, subapical markings also smaller ; black border 

 covering extremity of cell, origin of vein 4, and outer half of 

 vein 3. Hind wing : black terminal area diffusely limited 

 by a rather broad area of grey suffusion ; no discocellular 

 nor submarginal markings, the transparent red patches of the 

 underside taking their place. 



Below. — Fore wing dead- white, base yellow; black border 

 similar to above, discocellular and subapical white patches 

 somewhat larger than above. Hind wing : basal half 

 yellow, except a little white on costal part before black 

 terminal area, which is distinctly limited, but not regularly 

 rounded, passing through the extreniity of the cell from 

 beyond origin of vein 6 to that of vein 3. Red discocellular 

 patch rather large, occupying the whole lower discocellular ; 

 submarginal patches somewhat broader than in the ^, less 

 distinctly surrounded with white, the band regularly rounded 

 distally; black terminal border broad.

Note. — No doubt, many of the characteristics given above 

 will prove simply individual when large series are examined. 

 The racial character certainly in the r^ is the larger extent of 

 the apical black on the underside of the fore wing ; the ? 

 characters are given in Ann. & Mag. Nat. Hist. I. c. 



Terias lihythea dionysiaj subsp. n. 



(^ . Above. — Darker yellow than in T. I. zo^^aide^ Feld., 

 dusted with black scales at the base. Black border of fore 

 wing broader, extending to the point of separation of veins 6 

 and 7, narrowing regularly towards inner margin. Hind 

 wing: border broader, 2 mm. under vein 6, dentate on 

 veins 6 and 7, narrowing regularly and not so abruptly as in 

 T. I. zora'ide, Feld., and drona^ Horsf. 



Below. — Rather closely dusted with black scales, especially 

 on hind wing, but no traces of cloudy bands ; black terminal 

 dots on veins. Fore wing: a stripe on discocellulars, a 

 small dot in the cell. Hind wing: a small dot under vein 8 

 and one on lower discocellular. 



Genitalia (text-fig.). — Claspers somewliat broader than in 

 T. I. zoraide, more abruptly narrowed ; no dorsal hook nor
