Imago. — <£?. Fore wing grey, in the $ with a brownish 

 tinge ; the dark chocolate- coloured spots at the tornal angle 

 often coalesce into one, and that on M 2 is more or less excavated 

 distally : in the $ the spot on M 2 is divided into two ; there is 

 in both sexes a large chocolate submarginal patch extending 

 from the apex to R 1 , bounded by an inwardly curved line and 

 a dark transverse band across the base of the abdomen. 

 Hind wing reddish, the £ with fuscous at the base spreading 

 towards anal angle ; the chocolate-coloured anal spots 

 coalesce into a short broad band. Tibiae with very few spines ; 

 fore tibia ending in a long thorn as in Agnosia orneus. Antenna 

 long and stout, similar to that of sper chins. Tenth tergite 

 separated into two rather slender lobes ; sternite rounded at 

 the sides, apex pointed. Dorso-apical lobe of clasper pointed 

 (fig. 35 J), curving downwards; hook of harpe strongly 

 curved. Expanse : ^60-80 mm., $ 92 mm. 



Hab. E. Himalayas and S. India. We have bred it in the 

 Kanara District of S. India, where it is rare and very local, 

 being confined to forest- clad hills with heavy rainfall, under 

 1,000 feet elevation. - 



Larva : — 



Final instar. Very similar in shape to that of M . dyras dyras.

 each lobe ; true clypeus with the basal angles broadly rounded ; 

 false clypeus narrow and apex rising little above apex of true 

 clypeus ; labrum one-third length of clypeus and as broad as 

 clypeus ; ligula as long as labrum and half as broad, kidney- 

 shaped ; eyes 1 to 4 in a slight curve, equidistant ; 6 in line 

 with 3 and 4 ; 5 forming an equilateral triangle with 4 and 6 ; 

 3 the largest. Surface of head shining, covered with very small 

 glassy tubercles ; some larger, sparsely-distributed tubercles 

 on the cheek ; surface of clypeus transversely lined, with 

 a tubercle in each basal angle. Body similar to that of 

 M. dyras dyras. 



Coloration. — Head green, dorsal line and cheek whitish : 

 labrum, ligula, antenna and mandible very pale yellow, tip
