COSMOPTERYGID^. 



I have now broken up the family Elachistidce as formerly constituted, and 

 the family Cosmopterygidce includes those genera with long sickle-shaped palpi 

 and veins 7 and 8 of the fore wings stalked, 7 terminating in costa, such as 

 Cosmopteryx, Stagmatophora, and Limncecia ; in my last paper I termed this 

 restricted group Elachistidce, but now find that Elachista is referable elsewhere. 



Zaratha Walk. 



A genus of a few tropical species, having the antennte much longer than 

 forewings. 



Zaratha prosarista,n.sp.

 white. Palpi whitish, anterior edge of tei-minal joint dark fuscous. Antennas 

 dark fuscous, becoming yellowish on sides and whitish beneath. Thorax dark 

 grey, shoulders suffused with ochreous, beneath pearly white. Abdomen

 and almost confluent with a suffused yellow-whitish spot on dorsum rather 

 beyond it ; a slender yellowish streak along fold throughout ; a silvery-blue- 

 metallic line above this throughout, extended along termen to apex, where it 

 meets a silvery-blue-metallic subcostal line from | to apex : an ochreous- 

 yellow streak along lower margin of costal streak from indentation onwards 

 extended between the two blue lines to near apex : cilia rather dark fuscous
