cJ ? . In this species and its close allies the presence of some long, narrow, 

 whitish scales gives the body a pecnliar striated appearance. The pale discal band 

 of the hindwing is qnite variable in length and width, sometimes it reaches the 

 costal margin and is connected with the anal patch, in other specimens it does not 

 reach SC" ; the veins traversing it are occasionally all or nearly all black. E.xternai 

 spur of midtibia shorter than internal ; antennal segments of ? with prolonged 

 fasciculated ciliae. 



S. Tenth tergite gradually narrowed to middle, the sides almost parallel from 

 middle to end, upper surface of the distal portion evenly convex, under surface 

 concave, apex slightly curved downwards, with a faint vestige of a sinus ; sternite 

 twice as broad as apical part of tergite, obtusely rounded, upi)er surface almost flat, 

 transversely rugate. Harpe narrow, twisted, slightly spatnlate, irregularly dentate. 

 Ajiical margin of penis-sheath i)roduced at the right-hand side into a very short 

 tooth, denticulate or simple, at the left side into a longer, broader, dentate process 

 (PI. LVII. f. 13). 



W. Schans gave us the following description of tlie larva : " 75 mm. long, not 

 very stout, and ta])ering towards the head, which is very small and brown. Body 

 rich brown dorsally, paler laterally. A sulidorsal black streak, and on fourth 

 segment a small round ]iale brown spot representing an ocellus. Caudal horn long, 

 pointed, thick, slightly rough, brown. Laterally the pale brown is mottled with a 

 darker shade."'

 External spur of midtibia shorter than internal. Dorsal lines of abdomen parallel
