AGNOSIA. 209 



being less prominent than the median part. Horn dark 

 bluish-green, with paler tubercles on the dorsal and ventral 

 surfaces, and pale yellowish-green with larger tubercles of 

 the same colour on the sides and on the apical quarter ; anal 

 flap edged with yellow tubercles ; basal segments of true 

 legs pale yellow-green on the outer face and black on the 

 inner, second segment brown on the outer face and black on 

 the inner, third segment chestnut ; a black patch on venter 

 opposite the base of each leg ; prolegs and claspers of the 

 body-colour, feet pale brown. Spiracles oval, pale yellow 

 edged narrowly with green. Length 55 mm. 



Pupa. — Not recorded. 



Habits. — The large oval eggs laid sometimes singly, but 

 often in pairs, on the leaflets of a species of Indigofera, family 

 Leguminosae. The leaves of this plant close in the evening, 

 so the eggs must be laid early, or the leaflets must be forced 

 apart by the moth while ovipositing. The larva is sluggish 

 and deliberate in its movements. In the resting position 

 the front of the body is raised slightly from the surface, the 

 face parallel with the surface. In this position the subspiracu- 

 lar line of tubercles forms almost a straight line with the 

 oblique stripe on segment 5. The larva has the same habit 

 as some of those of the genus Clanis of remaining in the larval 

 state for a long period after burying itself in the ground. 

 Some larvae which went underground in September and 

 October 1932 had not pupated in May 1933, and others did 

 not pupate till June 1933. The moths emerged in about 

 a fortnight after pupation. 



Genus AGNOSIA Rothschild & Jordan. (Fig. 49). 



Roths. & Jord., 1903, p. 294 ; id., 1907, p. 60. 



Genotype: orneus (Westw.). 



Imago. — " $$. Tongue short. Joint of palpus open. An- 

 tenna of $ deeply grooved, strongly compressed, cilia long ; 

 in almost cylindrical, feebly grooved, basal fasciculate cilia 

 slightly prolonged. Tibiae not spinose ; fore tibia with apical 

 thorn, shorter than first tarsal segment (thorn excluded) ; 

 spurs short, one pair to hind tibia ; pulvillus and paronychium 

 present. Abdomen with spines all over the tergites, the spines 

 denser at the apical margins. Distal margin of fore wing- 

 entire. No friction- organ in £ " (Roths. & Jord., I. c. 1903). 



This genus differs from Clanis and Polyptychus in the proxi- 

 mal pair of spurs being absent from the hind tibia and in the 

 tibiae not being spinose.
