Family LEMONIID^E. 

 Subfamily Libyth^inj:. 



43. Ltbythea antipoda, Boisduval. 



Herr Kiihn has taken a single specimen of this species, and saw 

 one other. The identification is his, de Niceville has none from the 

 Ke Archipelago. 



Family LYC^ENID^E. 



44. Gerydus acragas, Doherty. 



Not very rare in Little Ke Island. Most frequently caught on the 

 young leaves of a species of Sambucus at rest amongst black ants, the 

 butterfly as well as the ants probably feeding on the sap of the leaf-buds. 

 The male has a small oval whitish patch surrounding the swollen base of 

 the third median nervuie on the upperside of the forewing ; no other 

 markings whatever on the upperside. The female lias the markings on 

 the upperside exactly as described for the species by Doherty. Both 

 sexes on the underside of the forewing have the markings exactly as 

 described by Mr. H. H. Druce in Proc. Zool. Soc. Lond., 1895, p. 561, 

 pi. xxxi, figs. 9, male ; 10, female, for G. vincula from Borneo. Doherty 

 unfortunately does not say if the submarginal band of confluent mark- 

 ings extends from the apex to the outer angle or not. G. vincula differs 

 from G. acragas in the female being uniformly dull brown without 

 markings on the upperside of the forewing. The "Miletus" chinensis, 

 var. ceramensis, Ribbe, from South and East Celebes, Amboina, Saigun, 

 Bum and Borneo (Iris, vol. ii, p. 247, n. 95, pi. v (nee i), fig. 2, female 

 (1889), appears to be quite the same as Geryden acragas, and has two 

 years' priority. 



45. Pithecops bassaris, de Niceville. 



P. bassaris, de Niceville, Journ. Bomb. Nat. Hist. Soc, vol. vii, p. 327, n. 4, 

 pi. H, figs. 4, male ; 5, female (1892). 



Rober as JEupsychellus (n. g.) dionisius, Boisduval. Ribbe as Plebejus 

 dionysius, Boisduval. It is found commonly on Little and Great Ke 

 Islands during the wet season on roads and paths through swampy 

 bush country. The genus Eupsychellus is a synonym of Pithecops. 



46. *Neopithecops zalmora, Rober. 



Plebeius lucifer, Rober, Iris, vol. i, p. 61, pi. iv, fig. 5 (188G). 



Not seen from the K6 Isles by us. It was described from the Aru 

 and Key Islands as P. lucifer by Rober. Heir Rober kindly sent
