white. Palpi white, extreme apex of second joint grey, terminal joint with 

 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 lanceoIate„. 

 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 ithree 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

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 hmdwings. 

 which is associated in direction with (i 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. 



Aetherasfis, n. g. 



Head with appressed scales : ocelli small ; tongue developed. Antenna? 

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

 rate, ascending, slender, second joint loosely scaled, terminal joint shorter 

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

 to tongue. Posterior tibias 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 i ; 3 and: 4 stalked, 

 r»-7 somewhat approximated towards base. 



Allied to ConiocW^es, from which it differs by the stalking of 3 and 4 of 

 forewings, and absence of vein 11. 



Aetherastis uranias, n. sp. 



9. 28 mm. Head, palpi, and antennae ochreous white. Thorax ochreous 

 white, with four black spots arranged in a diamond on back, and two others 

 on patagia. Abdomen whitish ochreous. Forewings elongate, moderate, 

 costa moderately arched, apex rounded-obtuse, termen obliquely rounded ; 

 white closely speckled with black and suffused with bright pale blue except 

 along costal edge and at base ; black basal dots on costa and in middle : 

 two small round black spots near base, viz., median and subdorsal, and three 

 others near beyond these, viz., subcostal, median, and subdorsal : cilia blue 

 white, basal third light ochreous yellow. Hindwings pale grey tinged with 

 whitish ; cilia as in forewings.
