47. Dasychira mascarenaj n. sp. 



(J . Primaries dull green, crossed near the base by two 

 interrupted white-bordered black lines followed by two 

 widely separated irregular dentate-sinuate white-bordered 

 black lines ; a sinuous discal series of white-bordered black 

 spots and a regular submarginal series ; fringe whity brown, 

 spotted with black : secondaries pale greyish brown, with 

 whitish costal area : thorax whitish, abdomen brown. Under 

 surface whitish, without markings. Expanse of wings 1 inch 

 11 lines. 



? . Altogether whiter than the male, the borders of the

" (5^ ? . Common about Fianarantsoa. Caterpillar has tufts 

 of black bristles. In cocoon 21 days." 



This species seems to be nearly allied to Desmeocrcera nuga- 

 trix of Felder; but (besides the specific difference of straight and 

 continuous black lines across the primaries) the artist has

 tennse, such as exists in no true Dasychira, but which may 

 appear to exist if the antennae are looked at from above.
