 underside of both wings pale grey, the fore wing with no 

 rough scales ; the hind wing with all the lines and shades

Spargania diver 'simt dia, sp. n. 

 S . 36 mm. — Face white, shaded with ochreous in middle; 

 palpus black, white at end of each joint; vertex of head 

 bright ochreous ; fore femur black above, ochreous whitish 

 below, fore and middle tibia and tarsus banded black aud 

 ochreous whitish ; thorax bright ochreous anteriorly, varie- 

 gated in middle, metathoracic tufts ochreous ; abdomen 

 marked as in cultata, Guen. Fore wing white, the area 

 beyond basal line strongly clouded with fuscous from less 

 than one-fourth costa to one-half inner margin, very obliquely 

 and irregularly bounded distally ; base with the scales very 

 varied, the effect being of dull olive dusted with bright 

 ochreous, almost golden ; subbasal line thick, black, sharply 

 angled in cell, followed by a white line before the dark 

 clouding ; antemedian line black, starting very obliquely 

 from a large triangular costal spot at about two-fifths, 

 crossing the cell-spot (which is large and black, slightly 

 larger even than in cultata), then very sharply bent base- 

 wards, and losing itself in the dark cloud; postmedian 

 blackish, in one specimen less distinct, lunulate-dentate and 

 somewhat zigzag, commencing from a costal black mark 

 near to that of the antemedian, oblique outwards to below 

 R 3 , thence approximately parallel to termen ; a submarginal 

 line from an oblique black streak at two-thirds costa, its 

 course nearly as in cultata, but the lunules between R 3 and 

 M 2 stronger; the area distally to this line dark clouded, 

 except between R 3 and M 8 , the apical clouding olive to the 

 subterminal, darker from thence to termen, streaked and 

 dusted with bright ochreous, almost golden scales; the 

 tornal clouding fuscous; subterminal white, dentate, only 

 distinct from costa to R 1 , where it is distally edged with 

 black, and towards tornus ; terminal line formed as in the 

 allied species ; fringe white, less pure in apical half, strongly 

 chequered with fuscous ; in addition to the above markings 

 there are some faint lunulate grey lines in the white areas, 

 as in the rest of the genus. Hind wing grey, with traces of
