202 THE PHOCEEDINGS OF THE LINNEAN SOCIETY 



tuft, concealed between labial palpi, of ? short, filiform. Fore- 

 wings moderately long, posteriorly dilated ; hind wings moder- 

 ately broad, slightly indented below apex. Fore wings with 11 

 veins ; 4 and 5 separate. Hindwings with 7 or 8 veins ; 2 close 

 before posterior angle of cell ; 3, 4, or 3, 4, 5, on a stalk. 



Also a considerable genus, occurring throughout the world. 

 Besides the two species described, there are certainly several 

 others ; but as all are very similar dull-coloured insects, and 

 variable withal, I forbear describing the rest at present. 



A. Forewings with a broad oblique blackish apical 



streak .. .. 1. strigiferella. 



B without apical streak 2. rufitinctella. 



Pemp. strigiferella n. sp. 



10"-12." Head greyish-ochreous, with a few whitish and black 

 scales. Labial palpi obliquely ascending, reaching somewhat 

 above head, greyish-ochreous, mixed with blackish at apex. 

 Antennae greyish-ochreous, in thickened, dentate, minutely 

 ciliated, with a large triangular tuft of black scales in sinuation. 

 Thorax greyish-ochreous, with two or three black scales. 

 Abdomen whitish-ochreous, sometimes infuscated, anal tuft of 

 cf ochreous, ovipositor of ? rather long. Legs greyish-ochreous. 

 Forewings elongate, strongly dilated, hind margin moderately 

 oblique, rounded ; greyish-ochreous, generally faintly irregularly 

 streaked with whitish below costa, often somewhat suffused with 

 greyish fuscous, and thinly sprinkled with blackish scales, especi- 

 ally between veins ; indications of commencement of a grey- 

 fuscous double very oblique first line on costa at one-third ; a 

 little above inner margin at one-third an oblong-elongate short 

 black mark, sometimes very conspicuous ; beyond this, above 

 middle of inner margin, a small dark fuscous cloud, sometimes 

 obsolete, often confluent with a cloudy dark fuscous streak along 

 posterior part of inner margin ; a double black spot before two- 

 thirds of disc above middle ; second line indistinct, double, grey- 

 fuscous, angulated inwards a little below costa, and again very 

 faintly above inner margin ; a conspicuous broad blackish oblique 

 apical streak, reaching from apex nearly to discal spot ; a hind- 

 marginal row of black dots ; cilia whitish-ochreous-grey, with
