snbmarginal Innnles themselves ; postdiseo-snbmarginal area white, with a wax- 

 yellow baud (= postdiscal series of bars), the upper three spots of the band more or 

 less isolated, sometimes faint, resembling somewhat the letter M, the band not 

 interrupted from 11" to SM', twice as broad as the anterior spots, or more, somewhat 

 dilated discad at veins, especially much dilated basad at (SM'), the additional 

 proximal portion — which corresponds to the distal end of tlie brownish yellow median 

 band of athani'is, eiulamippus, etc. - -cnt off from the band of the discal Innnles 

 M'— SM" not interrnjited ; edge of wing white with a faint blue or green tint, fringe 

 black ; end of veins thinly black. 



? . One battered specimen in the Tring Maseum ; somewhat larger than onr 

 largest <?<?, the teeth of the hindwing less acnte, otherwise like the c?. 



Tenth tergite of i broad, slightly emarginate at tip ; clasper with the upper 

 edge produced dorsad into a broad tooth of variable length and breadth. 



Length of forewing : c? 41 to 48 mm. 

 „ „ ? about .52 mm. 



Ilah. Assam to Palawan and .Java, from near the sea up to 4i)00 ft. 



Larva and pupa are unknown. The ? in onr collection was found alive in an 

 empty whiskey bottle at Ipoh, Perak, in August 1898 by Mr. Blaze. The larva 

 must have crept into the bottle to pupate. Unfortunately when breaking the bottle 

 to get the specimen out the collector injured the insect very much. 



We recognise four geographical forms which occur respectively in (1) Assam, 

 (2) Burma to Borneo and Sumatra, (3) Java, and (4) Palawan. 



The most interesting feature of the distinguishing characters of these four 

 forms is that the Palawan form agrees so well with the Assamese snbsj)ecies in the 

 lesser development of black on the upperside of the forewing as compared with the 

 subspecies from the other localities. 



A highly remarkable phenonomen in the habits of this species is observed by 

 Martin and Hagen (see E. delphis concha), namel}", the association of the J" with 

 Pieridae, which it resembles in its white colour.

c?. Upperside. Forewing : black area not so far extended basad between 



SO'' ' and R' as in the following two forms ; the white colour more or less 

 separating a spot from the black area in front of R- ; this spot corresponds to 

 median bar R' — R- of underside, and is sometimes very small, quite isolated, or 

 even obliterated ; j'ellowish white postdiscal spot SC'— R' 1^ to 4J mm. long, as a 

 rule concave distally, mostly followed by a second or even a third dot.
