Genus BASSANIA Walker. 

 BASSANIA AMETHYSTATA variety EXTREMATA, new. 



Forewing. — Pale olive-rufous; with tine black speckling; costal 

 edge dotted with pale; a mhiute black cell dot; the outer line runs 

 exactly as in the type form, straight from two-thirds of inner margin 

 to costa shortly before apex, but it is marked only by white dashes on 

 the veins and by the contrast of color between the rufous before the 

 line and a pale green shade beyond it, the outer edge of which is 

 toothed on the veins and on inner margin reaches anal angle; this 

 shade is followc^d above vein 7 by a blackish triangular blotch reach- 

 ing apex; marginal area and fringe rufous; near the base there 

 appears a pale green curved inner shade. 



llindwing. — Pale olive-straw color, 3'ellower toward inner margin, 

 toward hind margin reddish tinged and dotted with black, the reddish 

 tinge and speckling intensitied at anal angle and forming a dark ])lotch 

 beyond an undelined submarginal line; fringe dull lilac above middle, 

 chestnut-brown l)elow it. 



Under side as in tj'pe, with a short black zigzag line on costa before 

 apex, instead of a blotch. 



Head and thorax colored like forewing, abdomen like hindwing.
