14 miOPALOCERA MALAYANA. 



spots placed in pairs between the nervules, which become obsolete towards apex. Cell with either the apex 

 only or whole discal centre more or less pale subhyaline. Posterior wings above black or fuscous, with the 

 space between costal nervure and first subcostal nervnle ; the whole of cell, followed by two elongated spots, 

 situated beneath bases of first and second subcostal nervules, and two near bases of median nervules ; 

 basal two-thirds of subnicdi.-in interspace acutely dentate at apex, and basal two-thirds of internal area 

 pale yellow ; a discal row of small pale spots divided by the nervules, and a submarginal series of much 

 smaller, iiTCgularly shaped and arranged spots, both series becoming obsolete towards anal angle. 

 Wings beneath generally as above, but with the spots much more distinct, and with a marginal series 

 to hind wings. Head and thorax above spotted and streaked with white. Abdomen fuscous above, white 

 beneath. Sternum black, spotted with white ; legs black : femora streaked with white. 



Posterior wings with two distinct spatular scent-glands, largest on third median nervnle and smallest 

 on submedian nervure. 



Female. Larger than the male, with the apex of the anterior wings much broader, and the cell clearer 

 and paler ; marginal spots to hind w'ings clearly visible above. 



Exp. wings, 3 70 to 78 millim. : ? Sli millim. 



Hab.— Continental India; Assam (Warwick, Brit. Mus.).— Malay Peninsula; Province W^ellesley (coll. 

 Dist.) ; Malacca (colls. Moore and Brit. Mus.) : Singapore.— Sumatra.— Java.— Borneo (colls. Moore and 

 Brit. Mus.). 



The form designated by Butler as D. cwcea, which he originally described as distinct, but 

 which he afterwards * submitted as a var. of D. uspasia, seems to be a dominant, larger, brighter 

 and somewhat more melanic race of the Fabrician species. A very closely allied species or 

 race, D. jyhilomela, Zink., is found in Java. 



I have been unable to examine and measure more than one female, a specimen which 

 I captured myself in Province Wellesley.

Male and female. Wings dark fuscous, with pale bluish semihyaline spots and markings. Anterior 

 wing dark fuscous, with the following pale bluish markings : — three small elongate subcostal spots, the 

 fu-st commencing just beyond first subcostal nervnle ; beneath these spots are two elongated streaks, 

 followed by a subapical oblique series of three small and rounded spots ; nine irregularly sized and shaped 

 spots on disk, situated two above and three beneath first median nervule, three between second and third 

 median nervules, and one near posterior angle a little beyond a large streak (generally but not always 

 longitudinally divided) which occupies about basal two-thirds of interspace between third median nervule 

 and submedian nervure, and a submarginal series of small spots which become obsolete and obliterated 

 towards apex ; discoidal cell with a large discal streak (this is very irregular in size in different specimens).
