shortly triangular. Forewings subtriangular, in < with a 

 transparent spot at base of median cell, hindmargin with black 

 spots united by metallic-gold ; hindwings with basal pecten. 



Of the four species hereafter described, the first two hardly 

 fall well into the genus, owing to their longer palpi, yet they 

 possess the general characters ; the others agree with Eromene in 

 all respects. They may be tabulated thus : 



A. Forewings with broad silvery- white markings 2. bifractella. 



B. without distinct silvery-white markings 



1. Forewings with a central oblique fascia. 1. longipalpella. 



2. ,, with two slender transverse lines. 



a. Labial palpi hardly longer than head 3. praematureila. 



b. ,, ,, nearly twice as long as head ... 4. dilatella. 



^\ longipalpell\ n. sp. 



10" 11". Head whitish. Labial palpi twice as long as head, 

 whitish, mixed with dark fuscous scales, dark fuscous on sides ; 

 maxillary palpi white. Antennse whitish-ochreous. Thorax and 

 abdomen ochreous. Legs ochreous-grey, tarsi with ochreous- 

 white rings at apex of joints. Forewings elongate, rather dilated, 

 costa straight, hindmargin subdentate, slightly rounded ; ochre- 

 ous, suffused with white, especially on disc, which is almost en- 

 tirely white and rather thickly irregularly sprinkled with fine 

 black scales, especially towards posterior part of disc, sometimes 

 coalescing in parts to form irregular blackish spots ; towards base 

 the white colour forms a distinct median streak from base, which 

 shortly becomes dilated and suffused into the ground colour ; a 

 transverse central fascia of the ochreous ground colour, sprinkled 

 with whitish and blackish scales, gently angulated above and 

 below middle, bisected throughout by a violet-silvery metallic line, 

 indistinct on margins ; at two-thirds of disc, nearest to costa, is a 

 crescentic violet-silvery metallic mark, strongly margined with 

 black internally and less strongly externally; behind this are 

 four irregular elongate spots of black scales ; a silvery-metallic 

 outwardly-curved subterminal line, indistinctly margined inter- 

 nally with blackish ; costa before apex blackish ; a small white 

 spot on hindmargin in middle, a faint one below apex, and a 

 clear double one above anal angle ; hindmargin with seven black
