The Sarawak Museum examples are all wet season forms and 
the underside markings vary a good deal. In one female out of 
four, the fuscous colouring of the hind-wing extends well into 
the disc, but in the other two the blue ground-colour pre- 
dominates. 
Very variable both in the ground-colour and in the mark- 
ings. 
Distribution: India and Malaya.

A long and variable series in the Sarawak Museum from the 
following localities:—Lawas, Limbang, Banting, Gadin, Ku- 
ching, Busau, Mt. Penrissen—3,400 ft., Quop and Bidi. 
This* species seems exceptionally close to LZ. celeno and I 
have found great difficulty in satisfactorily separating the two 
species in the collection of the Sarawak Museum. Druce 
himself, in describing the species, threw out the suggestion 
i. Votes from the Leyden Museum. Vol. xen p. 139, 1891. “‘ List of the
