remained in our collection ever since unnamed. Mr. Distant has 

 taken this opportunity of describing two more novelties from the 

 same quarter from Mr. Horniman's collection. 



Danais FORMOSA, Godm., n, sp. (Plate XIX. fig. 1.) 



Exp. 4 in. 



Brovpnish black : basal half of primaries rufous ; a subquadrate 

 whitish spot near the end of the cell, a large irregular one below it, 

 divided unequally by the second branch of the median nervure ; 

 three small spots below this, and three transverse ones beyond the 

 cell, a fourth in a line with these nearer the outer margin ; two sub- 

 apical and a submarginal row of smaller spots : secondaries wiih 

 basal half whitish, divided by dark nervures ; two whitish spots 

 beyond the cell, above which is a dull rufous patch and a double 

 irregular line of submarginal white spots : below as above, but colours 

 paler. 



Hab. Gnuru Hills, East Africa (Last). 



Mus. G. & S. 



Resembles Danais petiverana, but may be easily distinguished 

 from that species by having the primaries more elongate and the 

 basal half rufous ; the basal streak withiu the cell and the two spots 

 below the first section of the median nervure are wanting ; the basal 

 half also of the secondaries is whitish, divided by blackish nervures. 

 D. petiverana appears to be identical with D. leonora of Butler, and is 

 closely allied to C. limniace of Cramer, and of which species it is the 

 African form. As Mr. Butler has pointed out, it differs from C. 

 limniace in having no white streak below the subraedian nervure, 

 and in the markings generally being broader. All our specimens of 

 D. petiverana are from the west coast, whereas the present species is 

 from the Gnuru Mountains in the interior, opposite Zanzibar. 



Physc^neura pione, Godm., u. sp. (Plate XIX. figs. 2, 3.) 



Exp. 1-8 in. 



Costa and exterior margin of both wings brown ; two parallel fine 

 submarginal white lines near the outer margin of both wings, within 

 which is a row of five rufous ocelli with faint black pupils ; a broad 

 brown streak on the inner margin of primaries ; interior area of both 

 wings milky white, showing the markings of the underside. Beneath 

 whitish, both wings crossed by transverse wavy blackish lines united 

 at many points ; a whitish interval on the discal area, beyond which 

 is an ochreous band marked with a row of five silvery spots in the 

 primaries and six in the secondaries ; tliere is also a round ochreous 

 spot with silvery pupil on the costa at the end of the cell, and three 

 fine submarginal parallel black lines in both wings. 



Hab, Gnuru Hills, East Africa (Last). 



Mus. G. & S. 



Closely allied to P. panda of Boisduval, but may readily be 

 distinguished from that species by its having the interior area of both 

 wings milky white instead of brown ; it differs also in other par- 

 ticulars already pointed out.
