Vnderside. Forewing : basal half rosy red, except costal ami inner margins, 



rest of n-ing yellowish olive-green ; a broad glossy discal band from costal margin 

 to beyond R', a large triaogular submarginal space of the same colour proximally 



bordered by an oblique blackish line. Hindwing shaded witli buff: a large rosy 



red patch between cell and abdominal margin, three yellowish green lines across 

 the disc : the tirst straight, Ti mm. from cell at R\ the second also straight, the 

 third dentate behind, the lines nearly equidistant. 



Vaginal plate (partly visible in fi/pr) with a high, almost rectangnlar, ridge : 

 the corners sharp, snmewiiat produced, distal edge trnncate-sinnate. Eighth tergite 

 trnncate, angles very strongly ronnded. 



Length of forewing : ¥ , OS mm.

J ? . Tongue short and weak. Joint of segments 1 and 2 of palpns naked, 

 open. Antennal segments of ? somewhat compressed ventrally, transsection 

 subtriangnlar, basal rows of ciliae distinct. Di.stal margins of wings entire; D- 

 of hindwing very oblique, twice as long as D'. Tenth abdominal tergite of S 

 deeply divideil into slender, hooked, pointed lol)es (PI. XXIV. f. 0. T. 8) ; sternite 

 membranaceous, withont lobes or processes. Clasper very broad, divided apieally ; 

 harpe prodnced distally into a long process (PI. XXXII. f 12. 1.3). No friction-patch 

 upon clasper, bnt the scales at the end of the eighth tergite curved inwards. 

 Penis-sheath (PI. XXX. f. 2i'>) with an arched belt of teetli which reaches the 

 apical edge at one side and is continued on the niembranaceons duct. Eiglith tergite 

 of? (PI. XVI. f 10) sinn.ate, with two or more teeth; vaginal plate produced 

 at each side of the cavity into a cnrved, pointed or dentate, process (Pi. XVI. 

 f. 14. 15). The lines and bands of the forewing are more pronounced in fresh 

 specimens ; the two straight double bauds in the basal lialf whicji run olp]ii|uely 

 distad from the costal to the inner margin are mure distinct in the ? than in the 

 6. Hi-side.s tlie large liasal jiatcli nnd the jiostdiscal band, which follows the curve

 Oisial margin more convex in ? than in c?.
