same plane as vertex of head, that is, slightly ascending from the longitud- 

 inal axis towards thorax ; the thorax itself is rather prominently humped,, 

 the front slope rather less (though much more than segment 2) inclined 

 away from longitudinal axis than hinder slope is towards it, the curve of 

 the two slopes being wide and even : about an angle of 125'' if it might be 

 expressed as an angle ; the hinder margin of thorax is a considerable 

 curve meeting the wing-lines on each side in a rather deep, rounded angle 

 of not far off 90° (say 80*^) ; the dorsal line of abdomen is very slightly con- 

 vexly curved thence to cremaster ; the lateral outline of head and segment 

 2 is a semi-ellipse (apex produced into the snout) placed on the thoracic 

 , portion of pupa which is somewhat suddenly broader, sloping shortly to 

 the shoulder bosses where the short, lateral wing-edge ridge takes its 

 origin ; the lateral outline of pupa then curves, gently and evenly, slightly 

 inwards (the breadth of pupa decreasing) to about segment 4, then out 

 again as evenly to segment 7, whence the pupa narrows gradually to the 

 cremaster; the ventral outline is slightly convex at head, then very slightly 

 concave (nearly quite straight) up to where it curves largely and widely 

 over the apex of wing-bulge back again to abdomen at segment 8, after which 

 the ventral line of abdomen is a straight line to cremaster ; if the line from 

 cremaster to shoulder-point is considered to be the longitudinal axis of pupa, 

 the straight front slope of the wing-bulge curve is at 45° to it; the cremaster 

 is a rather small, square piece with the extreme end a wide rounded 

 sinus leaving a blunt point at either angle, the sinus perhaps about the 

 depth of \ or t^ of the square piece ; this square piece is slightly con- 

 cave down the middle and is continued along sides of segment 14 (and 

 pupa) in a broad, well-defined, prominent, round-ended extensor-ridge ; 

 the ventral surface of cremaster is concave, the whole piece thin dorso- 

 ventrally and there are also two slight ventral, extensor ridges on the 

 vindersurface of segment 14, curved towards each other and ending in a 

 little free, blunt point or knob. Spiracles of segment 2 are linear, point- 

 ed at ends, flush, rather long, lighter in colour than the pupa ; the rest 

 are greyish white, with lighter, narrow, central, raised line and with a 

 fine, raised, green border-line ; they are not large, that of segment 11, 

 however, is much larger than the rest, that of 12 is blind. Surface of 

 pupa is very finely punctate on abdomen, imperceptibly corrugate-rough 

 elsewhere, the intervals between the lower parts flat and very little raised; 

 the snout transversly, deeply lined, often seemingly composed of two 

 pieces, one narrower than the other, end to end. Colour light green mottled 

 darker in round dots and spots ; the snout, lateral cremastral extensor ridges, 

 dorsal line of thorax (generally carinated slightly), shoulder points, a lateral 

 dot or spot at front margin of each segment (most prominent, sometimes a 

 little patch) on segments 4 and 9, a more or less obsolescent, dorsal, 

 spiracular and central, ventral line, some ventral, abdominal dots, a fascia 

 along inside edge of apical orange wing-patch orange (the area occupied by 

 the orange patch, in the imago that is), a discocellular spot, some powder- 

 ing on wing-surface : all these some shade of brown, some nearly black 

 others quite light. As often as not the pupa is bone-coloured with the 

 markings black or dusky when the change takes place where the green of 

 the leaves does not affect it. The antennee only reach to just before apex 

 of wing-bulge curve. L : 20 mm.; B : 5 mm. at middle ; H : about 9 mm. at 

 apex of wing bulge, 5 mm. at thorax-apex ; L. of snout : 1 mm. 



Hahits. — The egg is laid single on a leaf, dead stick or withered 

 part of the plant in any position and the laying is done rapidly ; 

 most generally a shaded place is chosen low down on the plant and 

 often right inside amongst the stems and branches, for the plant
