A REVISION OF THE ORIENTAL HESPERIID^E. 279 



Elwes's woodcut of austeni, also specimens agreeing with Moore's description of 

 moolata, and specimens agreeing with Moore's figure and description of Jcumara ; and 

 he goes on to say that all his Sumatran specimens appear to him to represent one 

 species, and that it may be subsequently found on an examination of the prehensores of 

 the male that some of these species may be valid. We give below a table of characters 

 drawn from the male genitalia sufficient for the separation of these species by any 

 person of moderate experience in the examination of such objects. The figures will 

 assist in the elucidation of these characters. 



A. Lower distal angle of the lower lobe of clasp produced much beyond the upper 



angle in a long nearly straight lobe; the upper distal angle produced into a 

 recurved lobe moolata. 



B. Lower distal angle of the lower lobe of clasp rounded, not produced. 



a. The two lobes forming the apex of the tegumen (seen from beneath) broad, flat, 



and subtruncate, their apices in the vertical aspect triangular austeni. 



b. The two lobes forming the apex of the tegumen (seen from beneath) narrow, 



pointed, and separate at the apex kumara. 



c. The two lobes forming the apex of the tegumen (seen from beneath) rather 



broad, curved, and connivent at the apex cahira. 



We also repeat here the external characters by which these four species may be 

 distinguished inter se : — 



Males. 



1 (2). Fore wing without cell-spots, or if one is present it is placed next the subcostal ; 



no white spot near the middle of vein 1 a kumara. 



2 (1). Fore wing with one or two cell-spots; if there is only one it is placed next the 



median. 



3 (4). Fore wing above with a white spot, sometimes reduced to a point, near the 



middle of vein 1 a. Fore wing below with a suffused blackish discal patch 

 from the base to the middle ; the pale spot near the middle of cell 1 a distinct, 

 suffused. Hind wing below ochreous brown cahira. 



4 (3). No white spot near the middle of vein 1 a on the fore wing above. 



5 (6). Underside : apical region of the fore wing paler than the disc of the hind wing, 



the latter deep warm (vinous) brown. Lower distal angle of the lower lobe 



of the clasp much produced moolata. 



6 (5). Underside : apical region of the fore wing concolorous with the disc of the 



hind wing, the latter reddish yellow-brown, Lower distal angle of the lower 



lobe of the clasp rounded austeni. 



With regard to the females of these species an exact knowledge can only be obtained 

 from specimens taken in coj)., but no real difficulty arises except as to the females of
