whitish strigulation on discal and dorsal portions of basal area, and median 

 band of whitish strigulation not reaching costa ; five pairs of oblique white 

 strigulae from posterior part of costa separated by dark fuscous strigulae, from 

 each pair a short blue-leaden mark, first and third prolonged as strigae to meet 

 two thick violet-leaden streaks enclosing ocellus, second of these interrupted 

 above tornus ; no black scales in ocellus ; cilia brownish-ochreous, a deeper 

 basal line, on tornal area whitish with line grey. Hindwings 3 and 4 coincident ; 

 dark grey ; cilia whitish-grey, a grey subbasal shade. 



Upolu, Malololelei, 2,000 feet, December ; 1 ex. Perhaps most nearly 

 allied to E. pervicax, of North Australia. 



14. Eucosma isomalla, n. sp. 



S 10 mm. Head white. Palpi white, second joint tinged ochreous towards 

 middle. Thorax ochreous- whitish. Forewings moderate, without costal fold, 

 termen nearly straight, rather oblique ; ochreous-whitish, obscurely strigulated 

 ochreous and slightly speckled violet-grey in disc and posteriorly, on dorsum 

 strigulated ochreous except anteriorly, on costa with about ten oblique fulvous- 

 ochreous strigae, with strigae of submetallic iridescence between these 

 posteriorly ; lateral margins of ocellus indicated by submetallic iridescence, 

 with three minute marks of two or three blackish specks each within it ; a small 

 round fulvous apical spot : cilia whitish, a dark fuscous antemedian and fuscous 

 apical line. Hindwings 3 and 4 coincident ; rather dark grey ; cilia pale grey,

Upolu, Aleipata, Lalomanu, November ; 1 ex. Nearly allied to the pre-

15. Eucosma involucrata, n. sp. 



S 16 mm. Head yellow- whitish mixed grey on crown, a blackish frontal 

 bar, face whitish. Palpi ascending, with appressed scales, pale yellowish, 

 second joint with basal, median, and apical blackish spots, terminal joint short,

 a large basal patch, its upper half mostly occupied by dark fuscous streaks, edge 

 running very obliquely from \ of costa to fold, where it forms an irregular pro- 

 jection, dorsal area marked with six suboblique bent streaks, of which first and
