•Allied to "P^ralts? jjolygraphalis''^'^] whitish stramine- 

 ous, with rust-red markings : wings sparsely reticulated, 

 especially the primaries ; an imperfect band across basal 

 fourth ; an externally sinuated band near the middle of the 

 wings ; a broad, external, diffused border to primaries, and a 

 submarginal stripe on secondaries : body pale fleshy brown, 

 the abdomen whitish towards the base. Under surface 

 whitish, the markings much darker than above, the central 

 band and the outer margin of primaries flecked with blackish 

 strigulge. Expanse of wings 17 millim.

4. Microsca nitens, sp. n. 



Coloration and general aspect of 3f. pallida ; sericeous 

 whity brown, slightly inclining to flesh-pink in certain lights ; 

 reticulated throughout the wings with dark brown : primaries 

 with a spot near base of interno-median area, a short band 

 from costal to submedian vein at about basal third, a central 

 curved irregular band from subcostal vein to inner margin, 

 and some irregular submarginal spots, pale vinous brown, 

 partly edged with dark brown ; subapical area suffused with 

 pale vinous brown ; a cuneiform white spot, edged and striated 

 with black, on outer margin at apex ; fringe pale vinous 

 brown, spotted with grey : secondaries crossed at about basal 

 third by a slightly irregular band, a little darker than those 

 on the primaries, and an irregular submarginal band, broken 

 up into fragments as on the primaries ; fringe as on pri- 

 maries : abdomen pale vinous brown towards the anal extre- 

 mity. Under surface silvery whity brown ; reticulations 

 more sparse, but blacker than above ; the bolder markings 

 copper-brown : primaries with the costal margin crossed at 

 regular intervals by two or four convergent black strigulae, 

 between which are pairs of longitudinal curved striaj, below 

 each pair of which is a pair of black dots ; subcostal area 

 from beyond the middle copper-brown, bounded below by a 

 longitudinal silvery streak, confluent with the apical spot, 

 which is also silvery ; below this again is a second (neces- 

 sarily bent) copper-coloured streak or band ; in and beyond 



* Two totally distinct species were described by Walker under the name 

 of Pyralis ? pohjgi'aphalis ; the above-mentioned (from Swan River) waa 

 subsequently named P. polyphoralis.
