and rather imaginary, the dorsal line there being without ridge or carina- 

 tion. The head seen from above has a deep semicircular sinus on front 

 margin, leaving a well developed conical point porrect from each eye, the 

 margin in the dorso-ventral direction thick and rounded as also the sides of the 

 head, the underside slightly convex : the thorax (segment 3) is twice as 

 long as segments 2 and 1 together, flat on side-slope from rounded dorsal region: 

 lateral outline of pupa continued in a straight line with segment 2, the two 

 sides diverging regularly to segment 7. i.e., the pupa increases regularly in 

 width up to middle of that segment which is 2-3 the total length from front 

 of head ; the width then decreases rapidh' to cremaster : that part of pupa 

 being more or less hemispherical on a base formed by a transverse plane 

 through pupa at centre of segment 7 ; the dorsal line runs from head, with 

 very little constriction (of pupa) at segment 5, up to culminate in the apex of 

 pyramid in centre of segment 7, the sides of dorsum of segments 5 to centre 

 of 7 being flat, sloping evenly from edge of pupa, including a slight expansion 

 of the wings, to the dorsal line ; cremaster fixed slightly on ventral side of 

 apex of hemisphere formed by anal 1-3 of pupa, stout, oblong, somewhat 

 curved, with a circle of six hemispherical small tubercles at base. The ventral 

 tine is slightly convex about middle, the wings being somewhat thickened at 

 ends. Spiracles oval, conspicuous, yellow with black central slits. The surface 

 is smooth and shiny. The colour is green, marked with a large spot at each 

 corner of segment 2 behind antenna, a larger one at apex of thorax touching 

 segment 4, one still larger at each shoulder, a broad band along centre of 

 segment 7 including the angular sides of the pyramid, wavy in outline not 

 bordered with black, anteriorly (the spiracle appears as a black spot in this 

 band) : all silver bordered with black. L.: 25 mm.; B: 15 mm. at segment 7 

 where the H : 1*35 mm. 



Habits. — The egg is laid on the upperside of a leaf in a shady 

 place in a ualla in the damp jungles of the Western Ghats from sea 

 level up to some 2,009 feet, very generally within a few feet of the 

 ground though sometimes 15 feet up. The little white egg-larva 

 settles itself down on the midrib when it emerges, making its first 

 meal as usual of the egg-shell, clothes its seat with silk and feeds 

 on the edge of the tough leaf : for the leaf chosen for the egg is 

 never a young one and the larva prefers them of a certain age. The 

 caterpillar eats in the evenings generally and, when bigger, goes 

 away to some distance from its bed to feed. When about to cast a skin 

 it will stand for hours with the front six segments raised in the air 

 at right angels to the rest of body. The flight of the imago is 

 powerful and rapid, consisting of downward strokes of the wings from 

 well above the horizontal to somewhat below it, in which latter posi- 

 tion the insect keeps them longest, sailing along thus. The males do
