( 227 J 



Underside more exteiuled pale yellow, especially the forewiiijr, than in the other 



species, tiie speckles not denser than ahove. Foi'ewing : the brown apical patch 



sharply defined behind, including white scaling;, costal markings as ahove, some 



larger speckles on disc indicating the exterior discal line. Hindwing : inner discal 



line more distinct than above, composed of speckles, not tonching cell, the external 

 discal line indicated by a small costal spot. 



Vaginal plate (PI. XVII. f. 1) proximally convex ; orifice ( F) very large, 

 its edge produced into a short tooth at tlie sides (n); at the hinder margin stands at 

 each side a long finger-like jirocess which is basally broader in a lateral than in a 

 ventral view, the ajiex of the process is obtuse ; i)ostvaginal part of plate (/"■/') very 

 short, membranaceous, scaled, no cavity behind the jirocesses. 



Length of forewing : o2 mm. 



S and early stages not Icnown.

cJ. Wings, upiiprsidt'. Forewing scarcely with any speckles, five costal 



spots, sharply marked, the first narrower, in front of base of M-, the second broader, 

 oblique like the first, before end of cell, the tbird at fork, at right angles to R', the 

 fourth small, in mm. from apex, the fifth subapical, narrowly crescent-shaped, with 

 some brown speckles near it, the spot and speckles situated in a very faint, deeper 



yellow triangle : fringe yellow like disc, witli minute black vein-dots. Hindwing : 



red speckles dispersed, none in apical half of cell, and only traces of a few in the 

 pale abdominal area, fringe pale yellow, blackish at anal angle, with a small spot 

 at vein 31'. 



I 'ndfisidc purer yellow than in the other species ; forewing brighter yellow in 

 basal two-thirds, with vestiges of minute speckles, a red bar in middle and a larger 

 reil spot at apex of cell, tr.aces of red spots behind M-, a short brown bar at fork, 

 a lunate snba[)ical spot shaded with a few white scales, preceded by a minute spot 



ns above. Hindwing : speckles' less numerous than in the other species, and less 



distinct. 



Antenna longer and stouter than in roiistrif/ilis, hindwing narrower. Tenth 

 tergite (PI. XXIV. f. 10) broad and short, sinuate, the lolies convex above, rounded ; 

 stemite produced into a long triangular j)rocess, which is much broader basally than 

 in cOHHtriyilis. Harpe entirely diffeient from that of i-onstriyiiis, consistiug of a 

 liroad obtuse process armed with many acute teeth (PI. XXXIII. f. 2). Penis-sheath 

 coding in u long pointed process (PI. XXX. f. 22).
