equal length ; a broad yellow transverse band slightly bayond middle, anterior 

 edge marked with two round golden-metallic spots, upper followed by a black 

 dot, lower shghtly posterior, band edged posteriorly by a golden -metallic 

 transverse line, interrupted in middle, beyond which however a triangular 

 yellow projection extends and is continued as a strong white sinuate line to 

 apex : cilia whitish-ochreous tinged with fuscous. Hindwings grey ; cilia 

 whitish -ochreous tinged with fuscous. 



Ivhasis, in September ; four specimens. 



Persicoptila chiasta, n. sp. 



$. 16 mm. Head whitish with a fuscous mark on each side of cro wn, face 



white. Palpi white, extreme apex of second joint grey, terminal joint with h^Z'L. 



two fine indistinct grey rings. Antennae ochreous-whitish, beneath dotted with 

 dark fuscous. Thorax light fuscous, with margins of patagia and a dorsal line 

 white. Abdomen light ochreous-yellowish, towards apex white, on sides 

 marked with blackish, beneath white. Posterior legs white banded with pale 

 greyish-ochreous, tibiae with very large expanded brush of light crimson- 

 rosy scales mixed with dark fuscous. Forewings very narrowly lanceolate, 

 widest near base and gradually narrowed to acute apex ; fuscous suffused with 

 dull crimson ; a narrow very oblique white facia beyond middle, and a trans- 

 verse rather inwards-oblique white line near apex, space between these pale 

 brownish faintly tinged with crimson, in disc at | with two or [three dark fus- 

 cous scales surrounded by indistinct white suffusion ; apical area darker fus- 

 cous, with a white apical dot ; cilia pale brownish, with some scattered black 

 points near base, at apex with a dark fuscous median line followed by a 

 whitish spot. Hindwings rather dark grey ; cilia pale ochreous, 



Ohiya, Ceylon, 6,000 feet, in August (Fletcher) ; one specimen. 



ETHMIADAE, 



I accept the suggestion of Mr. A, Busck that this is a good and distinct 

 family, separable from its nearest allies by the origin of vein 5 of hindwings, 

 which is associated in direction with 6 and 7 instead of with 3 and 4. The 

 two following genera are certainly referable to it, they differ from Echmia 

 in having 7 and 8 of forewings separate, but agree in all essential characters. 



Aetherastis, n. g. 



Head with appressed scales ; ocelli small ; tongue developed. Antennaa 

 I, basal joint large, with strong pecten of dense scales. Labial palpi mode- 

 rate, ascending, slender, second joint loosely scaled, terminal joint shorter J ^ yy,^_. 

 than second, pointed. Maxillery palpi very short, loosely scaled, appressed 

 to tongue. Posterior tibiae clothed with long rough hairs. Forewings with 

 2 from I, 3 and 4 long-stalked, 5 approximated, 7 to costa, 10 from near 

 end of cell, 11 absent. Hindwings 1, elongate-ovate, cilia ^ ; 3 and: 4 stalked, 

 5-7 somewhat approximated towards base. 



Allied to Comocritis, from which it differs by the stalking of 3 and 4 of 

 forewings, and absence of vein 11.
