290 Mr. E. Meyrick 07i the classification 



followed by small obscure white spots ; a row of four similar sx^ots, 

 preceded by small white spots, crossing wing from two-fifths of 

 costa to two-fifths of inner margin, third spot from costa largest 

 but not conspicuous ; a conspicuous white 8-shaj)ed discal spot, 

 margmed with blackish ; a small obscure white spot on middle of 

 inner margin, and another between this and discal spot, both pre- 

 ceded by dark fuscous scales ; a small dark fuscous mark on costa 

 above discal spot ; an indistinct interrupted dark fuscous line from 

 two-thirds of costa to disc at three-fourths, margined posteriorly 

 by several small white spots, only distinct on costa, becoming 

 obsolete below middle ; a cloudy dark fuscous line from apex near 

 and parallel to hind margin throughout, slightly margined with 

 white posteriorly ; cilia white, with a dark grey basal line broadly 

 hiterrupted below middle, and dark grey spots at apex, middle, and 

 anal angle. Hind wings sinuate below apex ; white, partly mixed 

 with ochreous in disc ; a straight dai-k fuscous line at one-third 

 from middle to inner margin ; an irregular dark fuscous discal spot, 

 cormected with inner margin by a thick curved dark fuscous line, 

 from apex of which proceeds a strongly outwards curved line of 

 obscm'e fuscous lunules to costa ; a broad pale ochreous hind 

 marginal band, cut near hind margin by an irregular dark fiiscous 

 line preceded by lunulate white spots ; cilia white, with an inter- 

 rupted grey line near base. 



Nearly allied to M. nitidalis, but white markings 

 much less developed ; discal white spot not separated 

 into two dots. 



Blackheath (3500 feet), New South Wales, in March ; 

 Deloraine, Tasmania, in November ; two specimens. 



Musotima nitidalis, Walk. 



Isojiterijx nitidalis, Walk., Suppl., 1417 ; Diathransta 

 timaralls, Feld., cxxxv., 23. 



Varies principally in depth of colouring. New Zealand 

 specimens being usually darker and more sharply 

 marked than Australian, and slightly smaller. 



Larva feeds on Adiantum (perhaps also on other 

 ferns), sometimes doing much damage in greenhouse 

 plants.
