M'/nwi Th.smi.,, HewiLson, 111. Diuni. Lep. p. 32, n. 16, t. 14, f. 25—27 (1863). 



I have not as yet received this species from the Malay Peninsula, 

 so have followed my usual course of copying both the original 

 figui-es * and diagnosis of the describer. 



" Upperside. Mnl<'. — Purple-brown. Anterior wing with the inner margin 

 curved, projecting. Posterior wing with three tails ; the outer margin and base 

 of the tails lilack ; a submarginal line between the tails, the fringe and the 

 tails white." 



" Underside. Anterior wing rufous orange, with two spots in and below 

 the cell, a spot at the end of the cell, three transverse lines (the first, which is 

 near the second, indistinct), the outer margin, and fringe, all brown. Posterior 

 wing white (the apex rufous), with eight brown spots, followed by several zigzag 

 black lines : the caudal spot, the lobe, and the space between them crowned 

 with silvery blue : a spot above the lobe also powdered with blue : the outer 

 margin black : the fringe white." 



" Female does not differ from the male, except that it is rufous-brown 

 above, and has the anal angle of the posterior wing grey, marked with the 

 caudal spots." 



Exp. wings, " Is'u inch."

Mr. Hewitson describes his species as closely allied to ill. ravindm, Horsf., a species 

 which belongs to the previous genus Drupadia, and so is structurally differentiated apart 

 from colour divergencies. Mr. Hewitson also writes, "A male in the collection of Mr. Wallace 

 has a rufous spot at the centre of the anterior wing, as represented in the accompanying 

 figure" (iig.TG).

Female. Wings above rufous-hrown ; posterior wings with a large greyish-white patch at area of anal 

 angle containing three indistinct bluish spots separated by the second and third median nervules ; abdominal 

 area greyish-white, with the margin brown; tail-like appendages blackish, with their margins greyish- 

 white. Anterior wings beneath reddish-ochraceous, with a transverse white fascia crossing end of cell and 

 widened towards inner margin ; this fascia is broadly margined with fuscous on each side and is outwardly 

 followed l)y a waved fuscous line crossing wing, which commencing at about middle of third subcostal nervule, 

 is widely fractured at the upper median nervule, and terminates on inner margin. Posterior wings creamy- 

 white, with the apex ochraceous, and with the following blackish spots :— two near base, three crossing 

 wing before middle, one near end of cell, and a curved outer series commencing beneath the first subcostal 

 ncrvulc! and terminating in a long and much angulated spot above the anal angle ; extreme posterior 

 margui black, a black submarginal line between the discoidal and first median nervules, three submarginal
