Genus 68.-DI0H0RRAG1A, Butler. (Plate XIX). 



Dichorragia, Butler, Proc. Zool. Soc. Lond., i86S, p. 614 ; Adolias, sect. 6, Felder, Neues Lep.,p. 35 (1861). 

 *' Most nearly allied to Apaiura (_A. ermiuia), but diffeiing slightly in the neuration, 

 the discoidal cell of the hindwing partially closed by an interrupted and rather delicate lower 

 disco-cellular nervule. In colouring the type more nearly resembles Symplucdra cyanipaidus^ 

 than anything else, which probably accounts for its retention in Adolias \_ — Eiithalia\. 

 Typical species DicJiorragia nesimachus." {Butler, 1. c.) 



Antennce very slightly more than half the length of the forewing. FoREWiNG with the casta 

 gently arched, outer margin slightly emarginate and waved, inner margin straight, about 

 equal in length to the outer. J^irst subcostal nervule given off near the end of the cell 

 second just before its end, third opposite the termination of the costal nervure, reaching the 

 apex of the wing ; upper disco-cellular nervule obsolete ; middle obliquely inwardly straight 

 for a greater portion of its length, then sharply angled outwards ; lozver at first straight, 

 upright, then angled outwards, joining the median nervure a little beyond the origin of the 

 second median nervule ; third median nervule much arched, submedian nervure sinuous. 

 Hindwing with the casta moderately curved ; outer margin gently waved, inner margin 

 deeply channelled to enclose the abdomen ; prcccostal nervure upright, simple ; discoidal cell 

 closed by a fine sinuous lower disco-cellular nervule, joining the median nervure exactly at 

 the origin of the second and third median nervules ; thi^-d median nervule arched at the base 

 then straight, 7?; j/ median nervule slightly sinuous, internal nervure \Qxy sinuous. 



Dichorragia is a genus of very small extent containing two species only, D. nesimachus 

 confined to the hills to the north-east of India and occurring again in Borneo, and D. nintis 

 Felder, in Amboyna and Ceram. The Indian species is of a dark greenish blue with numerous 

 irregularly disposed pale spots, with a highly dentate pure white marginal narrow band.

Habitat : Sikkim, Assam, Sylhet ; Borneo (Druce), 



Expanse : $, yoo ; ?, 3-37 inches. 



Description : " Upperside black, suffused more or less with green. Forexmfy with a 

 number of whitish spots disposed about the basal half ; at the extremity of discoidal cell 

 three longitudinal streaks, and above these on costal margin some narrow streaks white • a 

 double submargiiial row of narrow white zigzag lines, and a marginal row of white spots. 

 Hindiuing with whitish spots about the middle ; a curved row of black spots above a sub- 

 marginal row of narrow zigzag white marks, the latter more or less geminated about the 

 middle ; and a marginal row of narrow lunalated white lines. Underside black with 

 markings as above on foreioing, and tinged with blue, the spots on the hindwing bluish but 

 more or less obsolete, the surface of the wing being tinged with green ; the row of deep black 

 spots as above. Sexes alike." (Moore, 1. c.) The colouration of the female is somewhat paler 



and hind margin brown ; three lunular marks within and an outward curved streak closing the cell ■ a dentate 

 lunule below the cell ; a transverse discal confluent zigzag series of spots ; a suffused subapica'l patch • a 

 submarginal recurved row of broad oval spots ; a marginal row of dentate spots, and narrow exterior line 

 which is angled on the veins. Hind-Mtng with the base brown, indistinctly streaked with black and bordered 

 by a distinct black zigzag lunular band ; the outer portion marked as in forewing. Cilia alternately white and 

 black. Vnv¥.KSiDE.:/orewing fulvous, apex and exterior border streaked with yellow; markings narrower 

 and less defined ; anterior spots in submarginal and marginal rows with white dots ; a black patch at base of 

 hind margin. Hindwing dark ferruginous; disc clouded with yellow; two small pearly-white streaks at 

 base of wing, one above, the other below the cell ; a small black narrow streak at base and a white-bordered 

 black spot within the cell ; a curved median transverse band with irregular black angulated borders composed of 

 three pearly-white portions and yellow intervening spaces, the former disposed thus :— (i), between the costal and 

 subcostal ; (2), at end of the cell and divided by the disco-cellular ; (3), between the first and second median the 

 first and third being much constricted; a submarginal series of six white-centred black spots • a marginal 'row 

 of pearly-white quadrate spots, each well separated by a dark ferruginous streak, and bordered interiorly with 

 a narrow blackish dentate lunule. Body above blackish brown, beneath and legs dark yellow." 



" This species belongs to the " seUiie" group, and is allied to A.jerdoni, Lang, from Goolmurg on S -W side 

 of the valley." (Mooie, 1. c.) o • •
