Found chiefly in the Borneo siibregion, being recorded by 

 Sir G. Hampson from Singapore, Java, and Sarawak only. 

 Warren records its occurrence also in Assara, the Malay 

 Peninsula, Bali and the Natuna Islands. 



11. Eriopus concinna sp. n. 



(f , 9 19--20 mm. 



Antennal shaft normal. Tarsi glabrous; tibiae apparently 

 only (juite moderately fringed with hair ; cf with a broad 

 fold on proximal half of costa beneath, edged with very 

 broad down-turned scales, which almost entirely cover the cell 

 and extend across proximal end of submedian fold ; M^ rather 

 strongly down-curved at its origin in cf (scarcely so in 9)- 



Fore wing pale buff, banded with fuscous between the 

 subbasal and antemedial lines, more or less suffused with 

 rufous to postmedial line and slightly tinged with green on 

 terminal area, especially in the 9 . which has less dark 

 irroration than the cf > lines pale, waved, dark-outlined, the 

 subbasal and antemedial excurved throughout, the postmedial 

 excurved at fold, bent outward to hind margin ; claviform a 

 slight patch of black scales ; orbicular a black dot ; reniform 

 a more or less rounded patch of black irroration ; a triangular 

 dark mark on termen at about SC^ to R^, with oblique pale 

 teeth before and behind it. Hind wing whitish suffused 

 with fuscous, with slight discal spot and postmedial line ; 

 a line distally to the postmedial and the fringe paler. 

 U7iderside of both wings paler; hind wing with large, very 

 black discal spot and rather broken postmedial line ; fore 

 wing with weaker spot and line and with fringe tipped with 

 black. 



Mt. Poi, 5200 feet— 1 cf ; 4500 feet— 1 cf ; Mt. Penrissen,

This appears to be an Eriopus, although the areole is 

 minute (almost closed up), the scale-tooth at tornus is slight 

 and the thorax is clothed almosi, entirely with scales, hardly 

 "with hair and scales." Somewhat recalls a very small 

 Amyna species, but K^ of the hind wing is too much in the 

 middle of the discocellulars for that genus. The fold and 

 scales on fore wing beneath place it in a distinct section 

 of the genus.
