484 Mr. A. G. Butler on a Collection of 



Lyccenesthes 'princeps^ n. sp. 



$ . Wings above sliining lilacine brown, basal area shot 

 with pale cupreous brown, base and interno-basal area of 

 secondaries deep dull purple ; a marginal black line ; fringe 

 whitish ; secondaries with two white scale-tufts ; two or 

 three black subanal dots near outer margin ; abdominal area 

 brown : wings below much as in L. bubastus, pale brown, the 

 external half of primaries and the external two thirds of secon- 

 daries traversed by white-bordered pale brown bands ; secon- 

 daries with two blackish subcostal spots ; two anal submargi- 

 nal black spots dotted with metallic blue, and broadly bor- 

 dered behind with orange, the one at anal angle bifid, base 

 blackish : body below white. Expanse of wings 1 inch 

 2 lines. 



$ . Above bright purple, with the costal half and external 

 area of primaries and a clavate subcostal streak on secondaries 

 dark brown : primaries with three increasing submarginal 

 pearly whitish spots near external angle ; secondaries with a 

 discal angulated series of opaline lunules, five submarginal 

 spots, the fourth largest, rounded behind, almost entirely 

 orange, with a black centre, the others conical, white, with 

 brown centres : wings below much as in the male, but the 

 markings more strongly defined. Expanse of wings 1 inch 

 5 lines. 



Castalius resplendenSj n. sp. 



Wings above snow-white, basal area dusky, the basal and 

 internal areas brilliantly shot with silvery lilacine blue ; veins 

 dark brown ; a submarginal dark brown line ; costa of all the 

 wings dark brown ; primaries with a spot of black-brown at 

 the end of the cell ; a broad and very irregular black-brown 

 discal band from the costa to just below the first median 

 branch ; outer border dark brown, coalescing with the submar- 

 ginal line towards apex ; secondaries with a submarginal 

 series of black spots and a black marginal line : wings below 

 white, spotted and streaked with black ; primaries almost 

 exactly as in C. rosimon ; secondaries somewhat as in C 

 rosimoVj but the spots on the basal area smaller, fewer, and 

 more irregular, the disk also crossed by a zigzag series of 

 seven large spots, the inner submarginal series not double, 

 small and lunular; marginal or outer submarginal series 

 smaller. Expanse of wings 1 inch 3 lines. 



This beautiful little species of the section ' Castalius ' is 

 more nearly allied to C. rosimon than to any other Lyccena. 

 In the general pattern and coloration of the upper surface it 

 reminds one of lolaus Bowkeri.
