this interesting and rare species, which I have described above. 

 1 find it impossible to make out the neuration correctly without 

 clearing the wing of scales ; but the possession of the tufts of hair 

 seems to show that it is closely allied to Poritia, next to which I 

 have placed it. 



The type in the Hewitson collection, which is in poor condition 

 and has lost its abdomen, is the only female I have seen. On the 

 underside the markings are somewhat like those of Poritia, but 

 the wings are less thickly covered. 



PoEiTiA, Moore. 



When Mr. Herbert Druce wrote his list of Bornean butterflies, 

 one species only of this beautiful group was known from the 

 country, but shortly after Hewitson described two (1874). I am 

 able to include four new species, which, together with representa- 

 tives of species described principally from other localities, brings 

 the number up to about ten.

Pseudodipsas sumatrce, Feld. Eeise Nov., Lep. vol. ii. p. 259, 

 pi. xxxvi. tigs. 24-26 (1865) ; Druce, P. Z. S. 1873, p. 351. 



Labuan (Low). 



A single male in Messrs. Godman and Salviu's collection is my 

 only authority for including this well-known species. 



PoEiTiA PHOBMEBON, sp. n. (Plate XXXI. figs. 16 c? , 17 ? .) 



d . TJpperside brilliant emerald-green, closely allied to P. hewit- 

 soni, Moore, from which it differs by the fore wing possessing a 

 broad, ai-ched, green streak along the upper wall of the cell, ex- 

 tending from the base nearly to the end, sharply defined at its 

 extremity ; the black spot in the submedian interspace is large and 

 prominent. Underside greyer, with the bands broader and more 

 regular, and with their edges less distinctly prominent. 



2 • IXpperside : fore wing entirely without the ochreous which 

 is usually present in that sex of P. hetvitsoni, and without the 

 brown streak which is usual in the submedian interspace of that 

 species ; the blue streak in the cell as described in the male is 

 very prominent, and is entirely absent in P. hewitsoni : hind win"- 

 with a small ochreous streak in the cell at its outer extremity. 

 Underside as male, but paler. 



Expanse, cJ $ , 1 J^j inch. 



Kina Balu ( Waterstr.). Mus. Staudinger. 



P. jyhorn^edon is the Bornean representative of P. hewitsoni, and 

 presents sufficient differences to be considered distinct. It is also 

 a much larger insect. Dr. Staudinger writes me that he has only 

 received a pair.
