Undcrttule hazel-chestnut, rather brighter thau abdomen ; abdominal area of 

 hiudwiug cadminm-j-ellow. 



S. Tenth segment similar to that of vacillans. Glasper icith friction-scales ; 

 harjje and penis-sheath also not essentially different from that of vacillans. 



Larva (ace. to Butler) black : head and a series of lateral stigmatical spots

In the Tring Museum 64 specimens from : Ceylon ; Sonth India ; Ajmere ; 

 Dalhousie ; Sikhim ; Bhutan ; Khasia Hills ; Cherrapunji ; Tonkin ; Loo Choo. 



A close ally of .1/. racilhuiK, distinguishable by the absence of a yellow patch 

 from the fourth abdominal segment ami the much paler yellow band of the 

 hindwing. 



Linne's description of his helix is so short that it is impossible to say which 

 species of Macroylossum he had before him. Cramer's figure agrees best with 

 the present insect. 



The type oi pi/rrlmla is not preserved.

S ? . (Similar to bdis ; dark side-patches of fifth and sixth abdominal segments 

 less black, underside of abdomen and wings less reddish ; npperside of forewiug 

 with a whitish grey flush, the antemedian band broader behind, dilated basad

 concave between R- and hinder margin, interspace between the two lines filled u]) ;

 sjiace at its proximal side not sharply limited behind, continuous with the grey 

 snbmarginal area ; the grey median interspace rather conspicuous ; yellow band 

 of the same colour as in belis, i.e. deeper in tint than in cori/thits and allies. 



c?. Tenth tergite truncate-sinuate ; sternite transversely mnlticarinate on the

 shaped iit end, the small widened part dentate. Penis-sheath (PI. LVI. f. 21) 

 with a long apical process, which is somewhat widened and dentate before end ; 

 from its projecting base proximad extend two series of long teeth on to the sheath ; 

 internal rods obtuse at end. 



Larva (ace. to Moore, I.e.) brown or green, a dorso-lateral pale line from 

 end of ninth segment to horn, continued froutad by a series of thin brown dashes, 

 or by a vestigial line ; a series of dorsal dots.
