This is also in the Hewitson collection ; it certainly 

 belongs to the T. ada (not T. hippo group), both sexes being 

 at once distinguishable from T. andrea. 



21. Tachyris Dohertiella, sp. n. 



A very distinct little species ; male milk-white, the costa 

 bluish grey, browner on the costal border ; apex and outer 

 border occupied by a black-brown band, with acutely 

 dentated inner margin ; no subapical spot : secondaries with 

 a rather narrow and tolerably regular black-brown border 

 on a faintly blue-greyish ground from apex to below second 

 median branch ; fringe brown : body rather greyer than in 

 any of the preceding species. Primaries with the costal border 

 excepting at base chocolate-brown, continuous with the outer 

 border, which is much broader than above, blackish inter- 

 nally, with much less dentated irregularly sinuated inner 

 margin : secondaries slightly nacreous, with the outer border 

 chocolate-brown and broader than above : body below white. 



Expanse of wings 55 millim. 



? . Primaries dark brown, blackish towards apex ; two 

 narrow superposed creamy-yellowish streaks beyond the 

 cell ; an irregular white patch from just above second median 

 branch to inner margin, its inner edge diffused, its outer edge 

 acutely zigzag : secondaries with a smoke-grey basal patch ; 

 a moderately broad dark brown outer border on a pale 

 brownish ground from apex to just beyond second median 

 branch. Primaries below with the pale markings of the upper 

 surface extended ; the base and lower two thirds of the 

 discoidal cell whitish : secondaries nacreous, the outer border 

 paler and much wider than above.

 Keceived from the Godman and Salviu collection. 



22. Tachyris timorensis, sp. n. 



cJ. Very like T. lyncida, but with the black-brown outer 

 borders distinctly broader, less irregular, the subapical spot 

 sometimes reduced to a short narrow streak. 



Expanse of wings 54-60 millim. 



$ . Very like T. Dohertiella, but the creamy streaks beyond 

 the cell of primaries broader and confluent ; the outer border
