Mr. de Niceville appears to consider L. celeno, Cr., distinct from 

 L. mlianus {J owrn.B. N. H. Soc. 1891, p. 366). The types of 

 Mr. Herbert Druce's L. cu/naia ^ are before me, and are quite indis- 

 tinguishable from the common form of celeno. The forms alexis, 

 Stoll, and conferenda, Butl., seem to be quite unknown in 

 Borneo '. I think that both Messrs. Distant and de Niceviile are 

 wrong in placing P. (=L.) malaccanus, Eober, as a synonym of 

 L. (elianus, as the arrangement of the white bands oii the hind 

 wing is very different, the 4th band (from the base), which in 

 <eliamis extends upwards to the 2nd median nervule, is in Herr 

 Eober's figure entirely absent.

 _ L. optimus scarcely differs from L. cleodxis. Fold., on the upper- 

 side, and on the fore wing below the white bands are arranged as 

 in that species, but on the hind wing the 4th band (counting from 

 the base) does not reach the costal margin, but stops short at the 

 subcostal nervure. The outer margin of the hind wing of the 

 female on the upperside appears to be not so strongly marked as 

 in that sex of L. cleodus.

Both sexes of this species are contained in Messrs. Godman and 

 Salvin's collection, agreeing well with typical specimens. 



Lampides zebba, sp. n. (Plate XXXII. fig. 18 S ■) 



d . Upperside very pale whitish blue, shining as in L. cleodus, 

 but bluer. The apex of fore wing very slightly dusky. Hind 

 wing sometimes unmarked, sometimes with a blackish streak near 

 the anal angle. Underside : ground-colour rather dark grey, with 

 pure white bands arranged as in L. celeno in both wings, but with 

 the orange patch darker and much more extensive.

^ There are specimens in Messrs. Godman and Salvias collection of the 

 allied L. evanescens, Butl., from New Hebrides Is., which closely resemble 

 the form conferenda, Butl.
