Continental India as a questionable habitat at least ; but Bmlma is represented in, and lias 

 been recorded frorn t Ceylon, Nieobar Islands, Malay Peninsula, Java, Borneo, Batchian, Gilolo, 

 Bourn, and Ceram in the east, and northward from Siani, Formosa and China* 



The larva and pupa of M,juvenla, Cram., from Java, are figured in Horsf. and Moore's 

 'Cat. Lep. Ins* Mus. EJ.C.,' i-, pi. v., figs- 4 and 4« t and Dr. Horsneld (p. 123) states that the 

 larva there feeds on a plant bearing the native name of i( Simbukan-rambat/'

Male anil female. Wings above fuscous, with pale bluish markings. Anterior wings above with 

 a long narrow basal streak between costal and subcostal nervines followed by three elongate spots ; a large 

 gradually widening streak In cell, deeply notched externally and transversely broken hefoiv apex, followed 

 by two elongate spots ; two long and linear fascia? beneath cell, united at base, one running subparallel to 

 subniedian nervine, the other directed parallel to median nervure and derlexed before third median 

 nervule ; a discal oblique series of five spotB, the first and upper one elongate, third smallest, and fourth 

 and fifth largest. ; a .submarginal row of seven spots placed between the nervines, ami a marginal row of 

 small spots which tend to become obsolete at apex. Posterior wings with two elongate fasciie in cell 

 joined together at base, but widely divergent at apex, where there iB a linear slightly curved intermediate 

 spot ; a long curved linear fascia commencing from beneath base of cell and defected before third median 

 nervule, followed by n discal series of live linear spots; a submarginal series of about eleven small spots 

 and a marginal series of smaller ones—- all these spots and fascia? pale bluish ; two long greyish streaks on 

 each aide of internal nervure along abdominal margin. Underside of wings paler ; anterior wing with an 

 additional eighth spot to submarginal series, and the cellular streak quite divided before apex; other markings 

 of both wings generally as above. Head and thorax above black, with a linear marginal series of 

 white spots, and a central discal thoracic white streak. Abdomen fuscous above, much paler beneath; 

 sternum black, spotted with white; legs black; fore t Arise and intermediate and posterior femora 

 streaked with white.

Mr. H. G, Smith* gives this species as an inhabitant of Sumatra, which is doubtless 

 correct ; he, however, also adds its pseudo-parent form D. $imili$> from the same locality, 

 which has hitherto only been recorded from China and Formosa. 



Although, as previously stated, this is probably but a constant geographical race of 

 B. similh, I have treated it hero, with this reservation, as a distinct species, and shall follow 

 this qualified course where necessary throughout. The question of species and varieties can 

 only be properly estimated by breeding, and it is hoped that some Malay entomologist in 

 whose way this work may fall will add to our knowledge by so doing* At present we can only
