segments, In some individuals the spiracular patches are 

 wanting. In all these varieties the legs and prolegs are as 

 in the form first described. Length 70 mm. ; breadth 10 mm. 



Pupa. — Tongue -sheath well developed ; tip of tongue 

 spatulate ; antenna equal to fore leg ; a short, narrow coxal 

 piece. Surface slightly shining ; head and wing-case smooth, 

 edge of tongue-sheath longitudinally grooved ; thorax 

 obscurely corrugate ; abdomen more strongly corrugate 

 and also marked with small pits ; hind bevels of segments 

 8 to 10 with a row of small pits along their front margins ; 

 front bevel of 9 with a wide channel set with minute tubercles 

 along its front margin, the rest of its surface set with prominent 

 oval tubercles decreasing in size from the channel to the 

 hind margin of the bevel. Spiracle of 2 a narrow slit, the 

 hind margin of 2 shallowly emarginate and slightly raised 

 in front of it, a narrow transverse oblong lobe projecting 

 from the front margin of 3 behind it, the front edge of lobe 

 prominently raised, the hind edge deeply depressed ; other 

 spiracles oval, the surface rising gradually to a smaller convex 

 oval containing the central slit, which has narrow, raised edges. 

 Cremaster large, triangular, broadly truncate, a minute 

 tooth at each lateral angle of the truncation ; upper surface 

 smooth and shining, basal two-thirds convex, distal third 

 flat, lower surface hollowed, basal one-quarter broadly keeled, 

 and with lateral extensor-ridges nearly meeting basad. Colour 

 bone- colour ; a black dorsal stripe on frons and on thorax, 

 median line of tongue-sheath fuscous ventrally ; tongue- 

 sheath, wing-case, legs, antenna and tongue marked with 

 leaden-grey, transverse lines and bands ; dorsum of abdomen 

 with a russet tinge ; an obscure dark dorsal stripe ; broad, 

 broken, fuscous, lateral, ventral and ventrolateral stripes ; 

 spiracles black ; abdominal pitting and cremaster russet.

Habits. — Food-plants : Morinda citrifolia Linn. var. bracteata 

 Hook, in S. India, and Pdederia fostida Linn., in the Khasi 

 Hills., family Rubiaceae ; and also Sirychnos nuxvomica Linn., 

 family Loganiacese, in S. India. The larva, when alarmed, 

 throws back the head and anterior segments over the dorsum, 

 and ejects green fluid from the mouth.
