2ncl Form : markings as in the J st form but the ground-colour on 

 the upperside entirely pale yellow. Underside : apical half of cell and 

 disc of forewing up to the black band pale sulphur-yellow ; the oblique, 

 curved, black band as in the 1st form ; interspace a whitish ; the rest 

 of the forewing and the entire surface of the hindwing rich chrome- 

 yellow. — Male and female : antennee dusky black speckled with minute 

 white dots ; head in front with dusky greyish-green hairs ; abdomen 

 blackish ; beneath : thorax yellow in female, white in male, the abdomen 

 white in both sexes. 



Dry-season brood. — Male and female tqjper and undersides : similar to the 

 same in the wet-season specimens, but in the ms.le the dusting of black 

 scales on the upperside has almost, in some specimens completely, disap- 

 peared, while on the underside the ochraceous colouring is much paler. 

 Female: both dimorphs differ but little from the dimorphsof the wet-season 

 form, only on the upperside the black on the apical half of the forewing 

 and on the terminal margin of the hindwing is more restricted, while on 

 the underside the oblique, curved, black band that crosses the forewing 

 is distinctly narrower with a tendency to become diffuse. Expanse 

 60-74 mm. 



Habits. — Nothing is on record as to the habits. The distribution 

 is said to be " Sikhim up to 4,000 feet; Bengal; Western and 

 Southern India as represented by Guzerat, Poona, Kanara, Tra- 

 vancoi^e ; Ceylon; the hills of Assam, Burma and Tenasserim ; 

 also found in Malacca, Borneo, Sumatra, Java and the Philip- 

 pines.' Now de Niceville named the Kanara specimens sent to 

 him, neicmho and that is the only authority for the above " Kanara " 

 being given as a localitj^ where albina (==neumho) occurs ; as 

 remarked already, the insect that occiirs in Kanara is leis or ivarcli 

 and not albina. The locality " Poona " is probably upon 

 Swinhoe's authority ; but Swinhoe has made so many mistakes 

 about butterflies and moths occurring in Poona, where he kept 

 his collections and employed collectors, that it is quite probable 

 this is another ; although, of course, it is possible that leis-ivardi 

 may again have been mistaken for neumbo (it is the males that are 

 so alike). Guzerat simply must be a mistake for both one and 

 the other, his-ioardi feeds upon, a fact also already mentioned, a 

 tree that is only found in the evergreen forests in Bombay ; and 

 these exist as far north as Khandala which is in the Poona 

 District, but there are none further north, certainly not in Guzerat. 

 That tree is the euphorbiaceous Hemicyclia venusta. It is just 

 possible, of course, that albina, leis and wardi may be one variable 

 species occurring frora Ceylon right through India wherever there is 

 forest of the requisite description, up through Bengal to Sikhim, 

 and Assam and down through Burma and the Malay Peninsula, 

 and right away across the Archepelago to the Philippines. Some 

 rare individuals have been caught in Kanara of female leis-tvardi 

 which have the apex of the forewing, and the whole hindwing, on 

 the undersides, bright chrome-yellow, nearly orange.
