BUTTERFLIES FROM THE INDO-MALAYAN REGION. S3! 



Mr. Druce's description given above is so inadequate and the 

 figure of the species so rough (moreover the two do not agree, as the 

 spot in the forewing can hardly be said to extend almost to the anal 

 angle) that it is with some doubt that I have identified thePerak speci- 

 mens taken by Mr. W. Doherty in January- February, 1890, as the 

 signata of Druce, and which I describe more fully as follows : — 



Male. Upperside, botli icings and cilia deep rich brown (almost 

 fuscous), with a distinct dark purple bloom. Forewing with a snow- 

 white lustrous semi-transparent discal patch divided into three 

 parts by the median nervure and first median nervule ; glossed (on 

 both surfaces) in some lights with pale violet ; the anterior portion ex- 

 tending across the whole width of the cell towards its outer end, the 

 outer edge of this portion concave, the inner edge convex, attenuat- 

 ed anteriorly, so that this portion of the patch is of half the width 

 where it touches the subcostal nervure as it is at the point where it 

 rests on the median nervure ; the second portion of the patch is 

 triangular, and occupies the base of the second median interspace ; 

 the third portion of the patch is the largest, and reaches from the 

 first median nervule to the submedian nervure, with all its edges 

 evenly rounded except the anterior one resting on the first median 

 nervule. Hinduing unmarked. Underside, both icings dark dull 

 brown, but entirely lacking the purple gloss of the upperside. Fore- 

 wing with the white patch as above ; the inner margin paler. Hind- 

 uing unmarked. Antennae, black, the club anteriorly ochreous* 

 Palpi black, but the first and second joints with a patch of rich, 

 chrome-yellow scales on either side, and a similarly-coloured ring 

 round the eyes. Female. Differs only from the male in the discal 

 band of the forewing being narrower, of the same breadth through- 

 out, with qiute regular edges. 



Described from a single pair of specimens kindly given to me by 

 Mr. II. J. Elwes. Mr. Doherty has given me the numerous localities 

 (given above) for this most beautiful and remarkable species in 

 which he has caught it. He tells me that " It flies with immense 

 rapidity, and rests on the undersides of leaves with wide-spread 

 wings. The wings of the male give off a faint sweet odour." The 

 s of my solitary male specimen are almost entirely destroyed, but 

 part of one hind leg remains, which bears at the base of the tibia
