2. G-amana costalis, n. sp. 



Male. Smaller than Malayan specimens ; veins of both wings 

 conspicuously narrower, not being black-bordered at their base. On 

 the fore wing the costal border is blacker, being completely covered 

 basally ; the discocellular spot and the submarginal and marginal 

 spots are of half the size of those in Malayan specimens : hind wing 

 with the discocellular, submarginal, and marginal spots also about 

 half the size. 



Expanse, c? 3| inches. 



Hab. Nias Island, W. coast of Sumatra. In coll. British Museum. 



A Sumatran female in the British Museum, and another in my 

 coUecticin, which may possibly belong to this species, are both 

 smaller and darker, and have the veins more broadly black-bordered 

 than Malayan females of G. daos. 



Genus Ideopsis. 



Ideopsis, Horsf. & Moore, Catal. Lep. E.I. Co. i. p. 133 (1857). 



Danais, sect. 4, Doubleday, Gen. D. Lep. p. 90. 



Wings scmidiaphanous : fore wing narrow, triangular ; costa in 

 male slightly arched ; first subcostal branch emitted at about one 

 third before end of the cell and anastomosed to costal, second at 

 some distance before end of the cell ; upper discocellular bent inward 

 near its lower end and producing a short discoidal spur within the 

 cell from the angle, lower discocellular outwardly oblique ; first 

 radial emitted from below the subcostal at some distance beyond end 

 of the cell, second radial from near angle of the upper discocellular. 

 Hind wing bluntly oval; costal margin long, nearly straight; abdo- 

 minal margin long ; venation similar to Gamana. Antennae with a 

 short, broad, flat, spatular club. Apical joint of palpi pointed.
