the markings bolder. Palpi a little longer than in the male, hi both sexes the 

 legs are short, thickly scale on the tarsi and broad at the ends. The markings 

 on the undersides of the wings are all light mouse-brown in the middle, bordered 

 first rusty (sometimes diffused inwards), then dark-brow^ and, finally, white. 

 Expanse : male, 32mm.; female, 40*48 mm. 



Larva. — Head only partly hidden mider segment 2, rather large, dull brown 

 in colour. The general sJiape of the body is oblong, nearly quite parallel- 

 sided, depressed, the dorsal line nearly straight ; the segments are weU-marked 

 because of the dorsoventral, central, fleshy, short, somewhat romid topped, 

 conical tooth ; segment 2 is large, square, transversely only slightly convex with 

 four, accentuated, tooth-like productions on front margin, one subdorsal on 

 each side porrect and pointing slightly upwards, one larger, lateral, pointing 

 slightly out and up : segment 3 has the dorsoventral margin anteriorly provided 

 with 2 similar teeth on each side,smaller than those on segment 2 ; each succeed- 

 ing segment has one, central on the same margin ; segment 14 is semicircular 

 in shape and has a dorsal similar tooth directed straight back from the margin ; 

 the gland on segment 11 is situated near the hinder margin and is a 

 truncated cone pointing up and back ; the organs on segment 12 are not visible. 

 Surface more or less duU and covered with enamel-like, flattened, minute tuber- 

 cles ; all the teeth of segments 2-14 are surmounted by a single hair, those of 

 segments 2-4 stiff, longer, bristle-like ; segments 3, 4 have each one subdorsal, 

 small, conical tubercle on each side of dorsal line, each svirmomited by a hair ; 

 segments 5-13 also have got these hair-surmoimted tubercles ; at the base of 

 each leg there is besides , a small, similar tubercle. Spiracles large, oval, flush, 

 yellow. Colour of the body is green with a subspiracular, white line and a yellow- 

 ish-white, lateral line formed of a series of crescent-shaped marks with the 

 convexity upwards, one to each segment ; on segments 3, 4 the space between 

 these lateral lines is brown as well as the upper faces of the teeth of segments 2, 

 3, 4 ; the hinder margin of segment 10 between these lateral lines also brown ; 

 the gland -cone also brown, darker upwards. Sometimes the colour of the larva is 

 very dark, nearly black-grey but all the markings are then still visible. 

 L : 30 mm.: B : 6 mm. 



Pupa. — Very like that of Arhopala centaurus in shape but the body has no 

 loop fixing it, only the tail-fixing. The head is hidden from above ; segment 

 2 is of ordinary size, transversely convex, the dorsal line in the same plane as 

 the front slope of the thorax ; thorax long, convex, slightly compressed laterally 

 and, like segment 2, very slightly carinated in the dorsal line ; constriction 

 behind thorax slight dorsally, none laterally ; the breadth is the same from 

 shovilders to segments 6, narrowing thence to the front margin of segment 11 

 whence it broadens out again to the end which is horse-hoof shaped ; segment 

 13 only visible dorsally as a narrow strip ; the apex of the thorax is the highest 

 point but only slightly higher than the body at segments 6, 7. Surface shining, 

 very minutely roughened, quite naked, the gland-scar is a raised, circular mark 

 near the hinder margin of segment 11. Spiracles of segment 2 are narrow, 

 long, raised, transversely rounded, light in colour ; the rest of the spiracles are 

 of ordinary size, flush, oval and brown. The colour is grass-green with an 

 abdominal, dorsal, dark-green line ; the membrane between segments 9 and 10 

 is visible and brown in colour. L : 20 mm ; B : 6 nim. 



Habits. — Eggs are never laid on any tree that has not got red ants 

 {(Ecophylla smaragdina) on it. The larva is constantly attended 

 by these ants and is extremely restless, wandering about constantly 

 from leaf to leaf and is extremely cannibal in its habits as it will eat 

 any of its kind that may be changing its skin or pupating. One
