differs in the intervening area between the cell-marks being olivescent-yellow, the 

 upper discal oblique series of four spots and the two subapical spots also yellow, 

 and with a pale yellowish discal patch between the middle and lower medians. 

 nindwi 71 g vfith the basal dark area narrower and uniformly coloured ; crossed by a 

 well-defined discal olivescent-yellow band, which is broad anterioi-ly and decreases 

 maculai'ly to the lower median veinlet. Underside of a more ochreous-olivescent 

 tint ; discal and subapical spots on forewing, and discal band on hindwing, as ou 

 upperside. Expanse, (j 3 inches. Habitat. Ta Tong Kiao, Cbitia (Coll. P. Crowley

Genus MAHALDIA. 



Imago. — Male. Wings large, short, broad. Forewing very broad, subtrian- 

 gular ; costa much arched, apex obtuse, exterior margin slightly scalloped ; first 

 subcostal branch free in both sexes ; first and second subcostals emitted before end 

 of cell ; discocellulars curved, middle discocellular concave ; cell closed ; middle 

 median veinlet emitted from immediately before lower end of the cell. Hindwing very 

 broad, somewhat quadrate ; apex truncate, exterior margin scalloped and produced at 

 end of the upper median veinlet ; cell closed. Byes naked. Sexes dissimilar. 



Type. — M. Sahadeva.

Male. Upperside dark olive or sap-green, with a somewhat bronzy gloss ; cilia 

 alternated with white ; basal black-lined marks distinct and broad ; crossed by a 

 blackish diff'used discal and submarginal and a narrower marginal sinuous fascia, the 

 anterior interspace between the two former being defined by pale yellowish lunules 

 on the forewing and broader lunules on the hindwing. Forewing also with an 

 oblique transverse pale dull olivescent-yellow macular band composed of five spots 

 and a slight costal streak, extending from the costa to the lower median veinlet, the 

 lowest spot being somewhat obliquely-elongated and less defined posteriorly, below 

 which is a much less defined pale lunate patch, which latter is sometimes 

 accompanied by either a single very small or a duplex obsolescent slender pale spot; 

 before the apex are two small white costal obliquely-superposed spots, the 

 upper one minute ; the interspaces between the basal and middle cell marks and 

 between the latter and the discocellular mark being much paler olivescent-green. 

 Hindunvg also with a transverse medial discal pale olivescent-yellow macular band 

 composed of six decreasing irregularly-rounded spots. Underside greenish-ochreous ; 

 cell marks distinct ; crossed by a broad discal and a submarginal diff'used sinuous
