Male. Wings above blackish ; anterior wings with the cell and basal area luarkud witli pale 

 yellowish strigie and a basal subcostal streak, and with the following spots of the same colour :— two in and 

 before end of cell, two at extremity of cell, four subapical, an oblique series of live beneath cell and an 

 outer submarginal series of smaller spots, fringe alternately yellowish; posterior wings with the basal 

 area minutely speckled with yellowish, a broad and irregular macular pale yellowish transverse fascia 

 divided by the nervules, generally followed by a small spot between the bases of the first and second 

 median nervules, and containing a large black spot ocellated with bluish at the costal margin, an irregular 

 submarginal series of pale yellowish spots and the area between these and the transverse fascia minutely 

 speckled with yellowish, a dark red spot at anal angle posteriorly united to a small yellow spot and the 

 fringe alternately spotted with pale yellowish. Anterior wings beneath spotted as above, but with basal 

 pale ochraceous streaks both in and beneath cell, and with some ochraceous spots between the four 

 subapical and the submarginal yellowish spots; posterior wings with the base ochraceous, outwardly 

 margined with and inwardly containing a forked narrow black fascia, the central transverse fascia as 

 above followed by ochraceous containing a blackish spot outwardly margined with bluish in and near end 

 of cell, a transverse series of six similarly coloured spots beyond cell ; five blackish spots at outer margin 

 of the ochraceous area and a marginal blackish scalloped fascia ; other spots and markings as above.

Hab. — Continental India ; N.W. Himalaya (Lang & Hocking— Moore) ; Bengal (Moore) ; Canara,

 — Formosa (Brit. Mus.). — China; Foochow (Elwes). 



Mr. Wallace described his local form malaijatim as wanting "the two spots on the lower 

 margin of the cell of the hind wings," hut these are really present — though in a moditied 

 form — in all the specimens now before me from the Peninsula, excepting in one example 

 from Singapore. The width of the transverse fascia in the cell is also somewhat wider 

 than in the typical forms of P. eritlioiiius, but the differences seem simply of a local and 

 varietal character. In Western Australia a distinct form of this species is found, in the 

 P. stheiielus, M'Leay. 



As pointed out by Reakirt,* several descriptions of the larva of this species had been 

 published, which differed in several particulars. Since then the drawings of its transformations 

 made by the Bros, de Alwis in Ceylon have appeared, and may be taken as decisive.} 

 In Continental India the larva has been recorded by Capt. Hutton as feeding on the Citron ; I 

 in the Bengal Presidency its food-plants have been described, by Capt. Mortimer Slater, as the 

 "Lime, Orange, and 'Bel' tree";§ Mr. Hamilton's statement is that "the larva of this 

 butterfly feeds on the Lime and Citron"; i| in N.W. India Capt. Lang found this species 

 constant to the " Aurantiacefe " ; ^ at Mhow Mr. Forsayeth not only found the larva " on a 

 species of orange or sweet lime tree, a large shrub with green fleshy leaves and thorny 

 branches, common in Indian fruit gardens," but subsequently "on a small green herb,
