strong, tliongli resolving themselves under the lens into con- 

 densed irroration ; antemedian slender, generalljr indistinct ante- 

 riorl}', oblique outwards from one-third costa, strongly recurved 

 in cell, oblique inwards to about one -fourth hind margin, 

 faintly sinuous ; discal dot small but sharp ; median line 

 thicker than the others, well beyond discal dot, very strongly 

 oblique outwards from costa, very sharply bent subcostally, 

 thence very slightly obliquely inwards and sinuous, the sinu- 

 osities being, as usual, at the folds, but never very deep, some- 

 times scarcely appreciable ; postmedian fine, midway between 

 median and termen or slightly nearer to the former, parallel 

 with termen except at costa, where it makes a bend, though 

 less sharply than the median, sinuosities slight or very slight; 

 subterminal indicated by absence of irroration, accompanied 

 proximally by a band of stronger irroration, distal ly by a hand 

 of browner tone, sometimes partly obscured by the grey irro- 

 I'ation, but always noticeable, usuallj^ clearest anteriorly, not 

 I'arely showing a bright brown, almost ferruginous spot near 

 apex ; a narrow white line separates this band from the tei-minal 

 line, which is black, thickest between the veins, slightly inter- 

 i-upted at the veins and extends round the apex for some distance 

 along the costa, as in the sidmuotaia group ; fringe with a line 

 of stronger in'oration beyond the middle, distally hereto less 

 strongly irrorated than proximally. Hind wing with termen 

 not bent at R^ ; first line absent ; median just proximal to 

 discal dot, obsolete anteriorly ; postmedian slightly sinuous, nearly 

 parallel with termen ; distal area nearly as on fore wing, the 

 brownish band fading out at apex instead of becoming more 

 conspicuous, the terminal line not extended round apex ; fringe 

 as on fore wing. Under surface more weakly marked, that of. 

 fore wing somewhat suffused basally, that of hind wing whiter ; 

 first line and sometimes median shade obsolete or nearly so.

A. very distinct though unostentatious little species, recog- 

 nizable especially by the charactei-s printed in italics. 



AciDALiA (Pylakge) xepheloperas, sp. n. 



cj , 16-23 mm. ; 5 ? 19-23 mm. Superficially like GlossotropJiia 

 romanaria Mill., and rufomixtcita Rbr., but structurally an Acidalia 

 of the section Pylarge. Best described by a comparison with 

 the well-known A. submutata Tr., with which it entirely agrees 

 in the markings (though these are, on an average, more sharply 

 expressed), inchiding the continuation of the black terminal line 

 round the apex, and the tendency (sometimes very strong) to 

 blue-grey clouding in the distal area. Much smaller ; ground- 

 colour varying from ochreous whitish to reddish sand-colour 

 (much as in jralcJiellata Fab.), antenna! ciliation in both sexes 

 longei'. male hind tibia with a pair of spurs, face pale in lower
