sometimes vestigial ; Llue-blacl!:, scales feebly deutate, those of upper layer narrow 

 in apical area ; a large purplish red discal area ou hindwiug, entering cell, 

 extending from SC^ be3'oud M-, non-opalesceut, the red spots of the underside 

 shining through ; scales of this patch entire. On underside scales behind SM- of 

 forewing and some before SM^ elongate, entire. Tibiae simple, spinose. Abdomen 

 with red spot only at base. 



? . Forewing similar to that of male, less blue, scales dentate. A red band 

 ou hindwiug consisting of six spots, first and second smallest and usually isolated, 

 third, fourtli and fifth much longer than broad, scales dentate ; the spots smaller 

 below, paler, and all separated. 



Scent-organ : white wool from base to apex of fold, the wool short, even, as if 

 shorn. In one of our specimens there is a large cinnamon streak on fold (SM'_). 



Genitalia: cj. Tenth tergite with small tubercle on each side dorsally at base, 

 the lateral edge being somewhat dilated proximally of the tubercle. Clasper 

 rounded ; harpe of a similar type as in /-'. hfsunder and allies, long, reaching close 

 to apex of clasper, rounded-truncate, with about six large apical [teeth, no tooth 

 at ventral margin proximally of middle. Fenis-sheath acuminate.

Palpus black in both sexes, M- of hindwiug on a level with W or more distal. 



S. Forewing : a large green patch from M^ to hinder margin, contiguous 

 with cell, consisting of three partitions, the first and second or all three acuminate 

 distally, the scales composing the patch broad, rounded ; rarely a streak of 

 dispersed green scales in cell ; rest of wing velvety black, upper scales narrower, 



lanceolate, nearly all entire ; under scales dentate, broad. Hindwiug with or 



without red spot behind BI-, the spot not being opalescent. 



On underside the upjjer scales in posterior area of forewing entire and 

 lanceolate, lieing bidentate on rest of wing ; occasionally small creamy patches 



posteriorly on disc. Iliudwing always with three large rod contiguous spots 



li^ — (SM'), more or less shaded with white, and a small spot ou abdominal fold, 

 there being usually also a red dot R' — R- near margin and often a small spot 

 11^ — 11' in front of the patch of three ; a submarginal dot SO^ — R' does not seem 

 to be ever present. Tibiae not incrassate, spinose. 



?. Forewing opa(|ue, being very little jialer distally than basally ; there are 

 always at least two creamy or bufiish-white patches on forewing ; upper scales 



of forewing partly lanceolate, acuminate. Hindwiug : red band broad and 



euutiuuous either from R- or R' to abdominal margin, rarely represented by only 

 two isolated spots ; spots SC- — R- usually present, isolated, small as com2)ared 

 with the posterior spots ; red upper scales nearly all entire, except near abdominal 



margin. Scales on underside dentate, a very few in the white patch of the 



forewing lieing acuminate. 



Scent-organ : white wool not extending to base, the basal third of the fold
