segment 2 with two divergent, fine, tapering horns, one on vertex 



of each obe, as long as segments 2-4 together : surface of head is finely 



ha.ry of horns tuberculato. Spiracles circular. sn.all, inconspicuous, situated 



.m,ned.ately above the white band, hght brown .n colour. Surface of body 



covered w.th mmute hairs proceeding fron, transverse rows of small tube; 



cles. one from each tubercle, giving the body the appearance of being 



transversely hned. The colour of the body and head is rose, the body 



h.hter than the head ; the latter with a dark red semi circular band on 



face ; horns same colour as face wilh inner and outer side dark, this dark 



markmg conunued on to the heacf ; body with a sub-spiracular white band 



and a lateral hght line as well as a faint bluish dorsal line on the middle 



segments ; ventrum dark-rose. L. 41 mm over nil ^f ^i \.\. ^u u

The colour is sometimes white green, yellowish on the sides with a dark 

 bluish dorsal line and a si.nilar lateral line on segments 2 to 4 ; tail-points 

 and^horns rose-coloured ; head light dirty-yellow ; the spiracles are light. 



P^^i;a. (PI. I, fig. ])_The pupa is somewhat boat-shaped thouc^h the 

 thorax 3S humped -nd there is a considerable constriction, broad and no°t very 

 shallow, behind it; the head, seen from above, is trapeee-.haped but has 

 2 long, sharp processes, triangular in section, closely applied against each 

 other and only just separated at the points, directed straight out in a line 

 with the ventral line of pupa; these processes are applied to each other 

 along one angle, alnng which only they touch, one of the other edges of each 



onto he op of the eye. Shoulders broader than segment 2 from where 

 the lateral outlines of pupa diverge to segment 7, the wings are, therefore 



hghtly expanded; from segment 7 the abdomen, more of less circular n 

 section, narrows gradually to end. The ventral line is straight. Thorax 

 ^hghtly carinated in dorsal line. Ventrum slightly flattened alo;g centr 

 ug-surfaces flat. Cremaster short, square, strongly lidged doiLly and 

 laterally and veatrally, each ridge ending in a sharp point posteriorly wh"h

Uabus-The egg is laid on the underside of a blade of ara.s 

 and the larva lives there, falling to the ground if alarmed. It is ra'lhJr 

 shy and not a great eater. The puj.a is formed in an abnormal 

 manner: the larva attaches itself, with its head pointing upwards 

 ^0 a stalk, fixes its tail and then falls backwards so that the backs'
