HiEMORRHAGIA. 241 



a more or less club-shaped process. Penis-funnel large, 

 obliquely truncate or ventrally prolonged ; penis-sheath 

 mostly very slender, ending in a pointed or flattened process 

 which is dentate at end in one instance (gracilis), seldom 

 {venata) heavy, and armed with a dentate projection. 



t; $. Eighth tergite transverse, truncate-rounded, rather 

 strongly chitinized also in middle ; vaginal plate small, 

 proximally membranaceous, vaginal orifice on the left side ; 

 membrane connecting seventh and eighth segments (resp. 

 seventh segment and vaginal plate) rather long, there being 

 a cavitv all round between the two segments, allowing the 

 tail a free movement " (Roths. & Jord., 1903, p. 438). 



Larva. — Head round, body tapering slightly towards the 

 front and back from segment 7 ; horn down-curved. Surface 

 of head shining, with small tubercles ; body dull, with large 

 tubercles on segment 2 and small tubercles on remaining 

 segments and horn. Colour green dotted with white and 

 a whitish dorso-lateral stripe. 



Pupa. — Slender ; surface smooth and shining or dull and 

 Tugose ; colour dark brown. 



Habits. — Eggs laid singly on food-plants of the families 

 Rubiacese, Caprifoliacese, Rosaceaa and Dipsacese. Pupation 

 an a rough cocoon on or near the surface of the ground. The 

 moths fly by day, feeding and ovipositing on the wing, and rest 

 with the wings held horizontal.
