distinction in the colouring of the underside, but in reality this feature is very variable, and 

 a series of Ceylon specimens match in this respect with a series of continental specimens 

 of E. ariadne. 



Mrs. Wylly of Khorda, Orissa, has furnished me with the following description of the 

 transformations of E. ariadne. "Larva, 75 of an inch in length. Above black, with a 

 narrow dorsal stripe starting near the head and ending before reaching the tail, composed of 

 transverse stripes and dots of yellow ; beneath and legs purplish-red. The body covered 

 with six even rows of 3-branched spines; two long many-branched spines on the small 

 black head : moves its head from side to side when walking Food-plant, the Tragia involucrata 

 ( Bichitee, Bengali, Bic/ia, Ooriya), a twining plant with hairy and stinging leaves. Pqpa, 

 greyish-brown with a few dark shadings, a pointed projection on the thorax. Attaches itself 

 by the tail to its food-plant and stands out from it nearly horizontally, the body of the pupa 

 slightly curved downwards. Emerges in about ten days." The colour of the pupa seems variable ; 

 those I have bred in Calcutta when attached to the green stem and amongst the green 

 leaves of the food-plant were coloured green also ; the brown pupae may be attached to dead 

 leaves or stalks. 



An allied species to E. ariadne from Singapore and Sumatra has been described hy 

 Mr. Wallace. Mr, Distant in his " Rhopalocera Ivlalayana" is unable, however, to identify it. 

 The description is given below.*

•'Body, and w«/?§-j moderate-sized ; the latter scalloped; forewing angulated below the 

 apex. Head, moderate-sized, with a tuft of hairs at the base of each antenna. Eyes, pro- 

 minent, naked ; hairy in some African species. Aniennce, not quite half the length of the fore- 

 wing, slender ; terminated by a slight, gradually formed, but very short club, obtuse at the 

 tip. Palpi, elongated, rather slender, finely hairy, porrected further than the length of the head, 

 and elevated to about the middle of the eyes ; terminal joint about half the length of the pre- 

 ceding, slender. Thorax, of moderate size, woolly in front and behind. Abdomen, slender. Fore- 

 wing, moderate-sized ; the costal margin but sliglitly arched ; apex subtruncate ; outer margin 

 scalloped, angulated below the apex at the extremity of the upper discoidal nervule. Upper 

 disco-cellidar nervide very short, rather oblique ; middle scarcely longer, slightly curved ; lomer 

 much longer, straight, transverse, but very slender, uniting with the median nervure exactly 

 at the origin of the third median nervule. Hindwing, moderate-sized, subtriangular-ovate. 

 Outer tnargin strongly scalloped. Upper disco-cellular nervule arising very close to the base 

 of the branch of the subcostal nervure ; the lower very slender, transverse, and uniting with the 

 median nervure at a little distance before the origin of the third median nervule. Forelegs, of 

 the male very slender and short ; the femur very delicately hairy ; the tibia and tarsus of equal 

 thickness, and of nearly equal length, being together about one-fourth longer than the 

 femur. Of the female considerably longer than those of the male, but equally slender ; 

 the tarsal portion dilated into an elongate-oval mass, with the three intermediate joints 

 armed at the tip within with a pair of long sharp spines ; terminal joint very small and 

 oblique. MIDDLE and hindlegs, rather short, thickly scaly ; tibia armed beneath with rows 

 of short spines ; tarsus more thickly clothed beneath and at the sides with rows of short 

 spines. Claios, small, curved, acute, simple. Paronychia, very slender, bifid ; the outer 

 division almost setaceous." (^Westwood, I.e.) 



* Ergolis isceus, Wallace, Trans. Ent. Soc. Lend., 1S69, p. 333, n. 4 ; id., Distant, Rhop. Malay., p. 139 

 (1882). Habitat : Singapore, Sumatra. Description; "Size oi E. coryta" \_=E ariatine~\. Outline of 

 wings nearly even, with an angular lobe on the: fore-wing, waved stria; somewhat as in E. coryta {= E. 

 aria,iite\, but disposed in pairs, no white spot near the apex ; on the hindwing a series of distinct sublunulate 

 ring markings, each enclosing an obscure reddish spot. Undersiuk, forezmng dusky, the disc reddish- 

 brown, the borders pale, a dusky streak parallel to the outer margin ; hindiuing pale brown, the markings as 

 above, but the lunulate ring spots smaller, the outer border ashy brown. Female, like the male, but 

 paler, especially beneath. This species has probably been confounded with E. coryta [= E. ariadne] from 

 which the even outline of the wings, and the absence of the white spot, at once distinguish it." (^Vallace, 

 l.c ) In speaking of £•. i'(i/><7(5a«« (Lc.) he also says " A dark rusty-coloured species, with the forewing less 

 angular than in E. isceus."
