436 Mr. Butler's descriptions of Lepidoptera- 



middle and the secondaries at the middle ; a paler and more diffused 

 band beyond the latter, its outer edge zigzag ; secondaries also with 

 a submarginal stripe of the same colour ; an almost marginal 

 series of black points alternately placed with a series of small 

 brown spots at the base of the fringe ; markings below less strongly 

 denned. Expanse of wings, 23 mm. 



Peak Downs. 

 Allied to J. attributa. 



91. Idcea Jessica, n. s. 



Nearly allied to the preceding species, smaller, the primaries 

 more acute ; the band beyond the middle much nearer to the outer 

 margin, narrower, paler, and less irregular ; the discal band 

 following it better-defined upon the primaries, and with undulated 

 (not zigzag) external edge ; a submarginal series of grey-brown 

 spots on all the wings ; dots at outer margin extremely minute ; 

 secondaries with a black dot at the end of the cell. Expanse of 

 wings, 17 mm. 



Peak Downs. 



92. Idcea nivipennis, n. s. 



Snow-white ; wings crossed beyond the middle by two parallel 

 slender grey dentated lines and two subconfluent squamose stripes 

 near the outer margin ; a marginal series of very minute blackish 

 points ; primaries with a very slenderly ochraceous costal margin ; 

 a minute black point at the inferior angle of the cell ; face brown, 

 darkest towards the vertex of the head, the latter white ; front of 

 collar orange ; antennra brown, becoming white at the base ; under 

 surface snow-white ; the costal margin of the primaries ochreous 

 anterior COXSB yellowish ; anterior tibiae and tarsi brownish above. 

 Expanse of wings, 26 mm. 



Viti Islands. 



93. Idcea innocens, n. s. 



Belongs to the J. ornata group ; small ; chalky white, with small 

 but conspicuous black disco-cellular spots; a very irregularly 

 sinuous olive brownish line crossing the primaries in front of the 

 disco-cellular spot, curving inwards below it and then downwards 

 with a slight curve inwards to inner margin, crossing the 

 secondaries obliquely behind the disco -cellular spot at about the 

 basal third ; a faint indication of a brownish discal line, followed
