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

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

 of the hindu'ing is quite variable in length and width, sometimes it reaches the 

 costal margin and is connected with the anal patch, in other s])ecimens it does not 

 reach 8C- ; the veins traversing it are occasionally all or nearly all black. External 

 spur of midtibia shorter than internal ; anteuual segments of ? with j>roloiiged 

 fasciculated ciliae. 



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

 middle to end, np})er 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, ujiper surface almost flat, 

 transversely rugate. Harpe narrow, twisted, sliglitly sjiatnlate, irregularly dentate. 

 Apical margin of penis-sheath produced at tlie right-iiand side into a very short 

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

 (PI. LVII. f. 13). 



W. Schaus gave ns the following description of the larva : " 75 mm. long, not 

 very stout, and tapering towards the head, which is very small and brown. Body 

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

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

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

 darker shade."
