than in the pie\'ious species ; a dark lather indefinite hiniile closes 

 each cell. Secondaries with an indefinite dark marginal spot in the 

 interspace of veins 2 and 3. Underside, both wings white Mith black 

 spots, sufficiently white to almost obliterate the usual white edging 

 to the black spots. Primaries with a good-sized reniform spot 

 closing the cell, followed by a short postmedian series of four spots 

 terminating between veins 3 and 4 ; the four spots are arranged in 

 a slight curve, and the third from the costa is placed obliquely ; a 

 submarginal crenulate line, indefinite towards the apex. Secondaries 

 with a basal sjiot on the inner margin, two subbasal spots below 

 each other, a largish lunular spot closing the cell; an irregular 

 postmedian series of eight spots, the first largish on the costa over 

 the lunular cell spot, the second shifted far out, being one of three 

 placed in an arc, fifth spot shifted well inwards, sixth inwards again, 

 seventh largish, sublunular, well outwards, eighth far inwards on 

 the inner margin — this might be mistaken for a third subbasal spot, 

 but correctly it forms one of the postmedian series — a submarginal 

 crenulate-yellowish line, faint towards the apex and edged internally 

 with dark brown in the anal area, where the yellow is extended, a 

 small dark marginal spot in the interspace of veins 2 and 3. 

 Expanse, 42 mm.

 Type in my collection. 



Genitalia with the harpagines slightly hollowed in the centre and 

 with the sickle termination much more tapered from nearer the base, 

 whilst the hook itself is also rather larger tlian in washuna ; the 

 bristles in the fore part of the clasps are stronger, larger and more 

 abundant than in that species; the shape of the anellus is more 

 pointed ; the falces somewhat heavier, and the aedoeagus decidedly 

 narrower than in Trimcn's insect. 



Androconia. Broadly oblong, tapermg slightly, wider distallj', 

 rather small ; the distal edge flatter than the proximal ; eleven roAvs 

 of reticulations, which are placed well apart ; footstalk long.

cj. UiDperside. Both wings pale Fi'cnch grey with a delicate 

 silvery lavender gloss, veins finely blackish, cell closed by a blackish 

 crescent, prominent in the primaries, fine in the secondaries, no 

 tails. Primaries with termen broadly and indefinitely brown, in 

 which is a more or less distinct row of submarginal lunules. Under- 

 surface. Primaries whitish tinged with yellow on the costa and
