1. Elymnias discrepans. (Tab. VI., tig. 2 ,? , 3 ? .) 



Elyiimiaf! discrejiaiix, Distant, Ann. Mag. Nat. Hist. ser. 5, vol. is. p. 397 (1882). 



Male. Anterior wings above blackish, with the following bright bluish markings : — a short portion of 

 costal area about apex of cell continued in a subapical oblique fascia to lower discoidal nervule, and followed 

 by four submarginnl spots, placed between the nervules ; outer margin shaded witli castaueous-brown. 

 Posterior wings blackish, but somewhat paler than the anterior wings, and with a broad castaneous-brown 

 marginal band. Wings beneath castaneous-brown, thickly mottled with pale strigae; anterior wings with a 

 more or less distinct pale apical area, which is continued along outer margin ; posterior wings with a more 

 or less distinct pale, broad, and irregular submarginal fascia, and with a very pale bright bluish spot near 

 costa, situate between the subcostal nervules* (this spot is sometimes absent). Body and legs more or 

 less concolorous with wings. Antennte variable in hue, sometimes stramineous, mottled with brown above 

 and pale stramineous beneath ; or fuscous above and stramineous mottled with brown beneath, with the 

 apex pale stramineous. 



Female. Anterior wings above as in male, but with a large ochraceous, basal area, which occupies 

 lower portion of cell, the greater part of the space between second median nervule and submedian nervure, 

 and terminates near end of cell and the bases of the first and second median nervules ; the subapical fascia 

 and submarginal spots larger and paler blue in colour. Posterior wings pale fuscous, becoming paler and 

 shaded with dull ochraceous towards outer margin, and with a more or less distinct pale submarginal spot, 

 situate between the discoidal and first median nervules. Wings beneath much paler than in male ; the 

 anterior wings ochraceous near inner margin ; posterior wings with a very broad and well-defined pale 

 marginal fascia, and with a very pale liluish spot, situate as in male. Body and legs more or less 

 concolorous with wings. 



Exp. wings, (? 53 to G8 millim. ; 2 (one specimen) 60 millim.

This form has frequently been referred to by some writers as E. undularis. Mr. Wallace 

 pm'suecl this course iu 18(39,1 remarliing, however, "this very variable species cannot be 

 separated into its local forms, or races, without much more complete materials than at present 

 exist." Since that time such material has been procured, and as other races of this species 

 have received distnictive names it became necessary for me to treat this local form in the same 

 manner. The true E. undularis appears to be confined to Continental India, of which another 

 local race in Upper Tenasserim has been described by Mr. Moore. I In E. discreiums the greatest 

 amount of colour differentiation is found in the female, which also, iu comparison witli the 

 other sex, appears to be very scarce and rare. More than a hundred male specimens of tliis 

 species have passed through my hands, but the only female specimen I have received is the one 

 which is here described and figured. As I collected in Province Wellesley myself, where the 

 male is a rather common insect, and have examined several collections since my return, this 

 sexual disparity is very perceptible. It may, however, be more apparent than real, owing to the
