band outside the discal line of the forewing extending costally to near the apical 

 patch, which is brighter pink than in the allied species ; the costal angle of the 



transparent spot of forewing rounded oft', the proximal edge of the spot, oblique. 



The transparent spot of hindwing large, more than twice as long as broad, its basal 

 end obliquely truncate anteriorly and rounded off posteriorly; the pinkish grey 

 discal hand narrow, hardly at all dilated posteriorly, dentate, as on forewing ; the 

 posterior submarginnl spots small, except the last one, which is large above aud 

 beneath. Tenth abdominal tergite (of 6 ) slender in side-view, the apical pro- 

 cesses short and acutely pointed. The apical lobe of the clasper broad. The penis- 

 sheath with three black teeth, two standing on the soft portion, and one at the 

 strongly chitinised apex on the left side. 



Length of forewing : 57 mm.

Besembling also R. joritlla Irbam Gner. (ISC!)), but the discal line of the 

 forewing is much more dentate, both wings are rather narrow, t lie transparent 

 spot of the hindwing is longer, and the pinkish grey discal area of the hindwing 

 is less dilated behind aud more distinctly dentate, aud the genitalia are ipiite 

 different 



1~. Rothschildia erycina nigrescens subsp. nov. 



?. Central area of both wings much washed with black: the pinkish discal 

 area narrower than the space from this band to the margin of wing ; outside 

 this pinkish area, which on forewing extends to the tip of the transparent spot, 

 there is a brownish black band, which extends forward to R 1 on hindwing. 

 Between this band and the margin the forewing bears Vandyke-brown patches, 

 followed by a drab band, while the hindwing has a row of large black double 

 spots, outside which there is a row of heavy black bars ; transparent spots smaller 

 than in R. e. erycinas. The underside shows similar differences from R. e. erycina 

 as the upper.

13. Rothschildia erycina rnartha subsp. nov. 



?. Similar to the preceding subspecies, but approaching R. erycina erycina. 

 Central area of both wings more shaded with black than in erycina, but less 

 than in nigrescens ; discal pinkish area of hindwing broader than the marginal 

 area, the brown baud outside this area narrower than in nigrescens and some- 

 what lighter blown ; the black snbmargiual spots of hindwing smaller than in 

 nigrescens, and the bars situated distally to them thinner. Transparent spots 

 still smaller than in nigrescens.

14. Rothschildia erycina vinacea subsp. nov. 



cJ¥. Brighter wine-red than 11. e. vryeiua; the black borders of the aute- 

 median and discal lines wider; the transparent spots larger. Forewing: the 

 patch at the apex of the transparent spot black ; the pinkish discal ares 

 narrower, bordered distally by an undulate, creamy or nearly white, line between 

 ll 3 and M 2 ; outside this creamy line- a blackish browu line, which is narrower
