256 THE LEPIDOPTERA OF CEYLON. 



VITESSA EAMA (Plate 178, Fig. 4, $ ). 



Forewino- with an interrupted transverse basal and a subbasal band, and the 

 outer half glossy blue-black, the intermediate basal area ochreous ; the middle area, 

 a laro-e oval discal spot and a lower streak, and very slender longitudinal streaks 

 between the outer veins glossy white : hindwing white, with a costal and broad outer 

 maro-inal black band ; the cilia edged with white. Head, thorax, first and second 

 joints of palpi, basal joint of antenna3 in front, and anal tuft ochreous-yellow ; 

 thorax with large black spots; abdomen black, with white bands; antennae black ; 

 femora above, tibia?, and tarsi black ; femora beneath, bands on tibige and tarsi, and 

 the spurs, white. 



Expanse 1^ inch. 



Comparatively smaller and shorter than V. Suradeva. Forewing with the basal 

 bands slightly broader, and the white streaks between the outer veins conspicuously 

 more slender : hindwino- with the white basal area smaller in size, and the marsfinal 

 black band of more equal width and broader at the anal end. All the legs and 

 tarsi with white bands. 



Genus TYSPANA. 



Differs from Vitessa in the forewing having the costa somewhat arched and the 

 apex convex ; first subcostal emitted at one-fourth before end of the cell, third and 

 fifth from the end, third liifid ; discocellular slightly concave, radial from near ujoper 

 end ; two upper medians from angles at end of the cell, second near the end, first 

 (or lower) at one-third : hindwing rather long, exterior margin convex ; cell about 

 one-third the length ; two subcostals from end of the cell ; discocellular bent out- 

 wardly before the middle, lower end long and oblique ; three upper medians from 

 angles at end of the cell, lower at one-third ; a submedian and two internal veins. 

 Body moderately stout ; abdomen keeled above, apex pointed ; labial palpi obliquely 

 ascending, laxly squamous in front, short, extending only half its length beyond the 

 head ; maxillary palpi slender, ascending ; legs squamous ; tibice slightly pilose ; 

 middle and hind spurs long ; antennge setaceous. 



TYSPANA VITESSOIDES (Plate 178, Fig. 3, 3a larva). 



Forewing pale sulphur-yellow ; with an interrupted purplish-black transverse 

 narrow basal, an outwardly-oblique subbasal, an entire discal band, and longitudinal 

 streaks between the outer veins ; cilia also black : hindwing white, with the 

 costal border and broad outer marginal band pale purphsh-black ; cilia giau- 

 cescent-black. Thorax, head, and base of palpi sulphur-yellow ; abdomen ochreous- 

 yellow, with black bands on basal segments ; thorax striped with black ; antennge,
