and the yellow intervals hardly visible ; in perj/ara exactly the opposite conditions 

 prevail ; the forewing is snfFused with yellow slightly flushed with reddish and the 

 lines stand ont distinct and ]inr])Iish black or dull red, with the cell-sjiot large and 

 black, the yellow hiudmargin and fringe not forming a contrast with the ground- 

 colour ; in the form tnarginata the red deepens into purplish black before the yellow 

 hiudmargin in both wings, and in the forewing a irarplish black streak runs from 

 l)ase along the centre of wing, widening to the end of vein 4 ; in the hindwing of 

 jier/iaxa the red ground-colour remains ty])ical, but the ccatral fascia is filled up with 

 purplish black.

 43. Crypsimetalla fimbriata spec. nov. 



Forcu-iiKj : olive-grey, the slightly darker basal two-thirds limited by a straight

Distinguished from ( '. aiiratu Warr., which it otherwise resembles, by the hairy

ForariiKj : yellowish bnlf, with slight dark freckling ; costa with minute 

 black dots ; a fulvous streak along costa at base ; traces of a vertical line at one-

 middle, touching at middle a ditfuse , irregular grey blotch at end of cell ; fringe 

 dark grey, finely interrupted by slender dashes of pale ground-colour beyond veins, 

 more widely at vein 4 and anal angle. 



Ilimhcing : with a diffuse grey band from end of cell towards anal angle ; 

 fringe yellowish, except along the excision between veins 4 and (i, and there 

 dark grey. 



Underside deep yellow with brown speckles ; both wings with a patch at base 

 of costa and a somewhat interrupted median band of dark brown scales coarsely 

 spangled with silvery ; a silvery submarginal blotch on each side of vein 6. 



Head, thorax, and abdomen yellowish buff; the base of shoulders and ])atagia 

 brown. 



Expanse of wings : 16 — 17 mm.
