Male. Anterior wings above pale grecDisli-white ; costal margin— very narrowly— and apex and 

 outer margins — broadly— dark fuscous. Posterior wings above bright ocbraceous, with some scattered 

 small and obscure fuscous marginal spots. Wings beneath dark sulphureous ; anterior wings with the 

 internal area — beneath cell and lower median nervule— pale greenish-white; a duplex pale castaneous 

 spot at end of cell, a waved and broken pale castaneous fascia betw-een end of cell and outer margin, 

 and the apex and outer margin of somewhat the same colour ; posterior wings with two small pale 

 castaneous spots at end of cell, followed by an outer discal waved and broken pale castaneous fascia, and 

 with small dark marginal spots as above. Body above greyish-white, the pronotum clothed with pale 

 greenish hairs ; abdomen beneath grej'ish-white ; thorax and legs ocbraceous ; eyes dark castaneous. 



<? . Var. ((. — Anterior wings above with the apex, costal and outer margins very pale brownish ; wings 

 beneath with the discal fasciae almost obliterated. 



Female. Anterior wings above as in male, but with the apex and margins more broadly and 

 irregularly dark fuscous, and with a narrow, angulated, macular fascia between end of cell and outer 

 margin. Posterior wings paler ochraceous than in male, the dark marginal spots very large and with 

 faint indications of a dark macular fascia between end of cell and outer margin. Wings beneath as 

 in male, but with all the markings broader and darker, and with some additional spots near base of 

 posterior wings. 



Exp. wings, (? and 2 , 57 to 75 millim. 



Hab. — Malay Peninsula ; Province Wellesley (colls. Saiier & Dist.) ; Malacca (Pinwill — 15rit. Mus.) ; 

 Singapore (Kerr — coll. Dist.). — Sumatra (Snellen). — Java (Horsf.); Batavia (Snellen). — Lombock; Timor 

 (Wallace).— Celebes (coll. Dist.). — -Teruate, Batchian (Wallace). — Australia; Champion Bay (Boulay — 

 Brit. Mus.) ; Port Essington (Brit. Mus.). 



This is a variable sjiecies, aud the hgures here given represent the form existing in the 

 Malay Peninsula, which certainly does not reach the maximum of size and coloration as 

 found elsewhere. 



The larva and pupa, as found in Java, have been figured by Dr. Horsfield,* who states 

 that the larva "feeds on various species of Cassia, particularly on the Cassia fistula and 

 C. obiusifolia." " It is, however, occasionally found on other plants ; it is extremely abundant, 

 particularly in the early part of the rainy season, after the renewal of the foliage of these 

 plants."!
