genera Acrolophtis and Anaphora. 167 



Felderia filicicornis, n. s. (PL VIII., figs. 22, 22 a). 

 Labial palpi strongly recurved, reaching to the posterior margin 

 of the thorax. Antenna strongly bipectinate, the pectinations 

 being slightly narrower at their bases, wider outwardly, sub* 

 ochreous. Head, thorax, mid palpi thickly clothed with fuscous 

 hair-like scales, tipped with hoary white. Fore wings mottled 

 greyish and brownish fuscous ; about twelve brownish fuscous ill- 

 defined dots along the costal margin, not arranged in pairs, but 

 distributed at approximately equal distances ; a brownish fuscous 

 spot at the end of the cell, from which a streak of the same colour 

 extends obliquely downwards to the anal angle ; fringes greyish 

 fuscous, speckled with whitish. Hind wings brownish, with a 

 faint purplish tinge; fringes pale greyish brown. Abdomen 

 brownish. Under side of all the wings pale cinereous, the costal 

 margin of the fore wings not defined by a pale line as in arizonella. 

 Exp. <il. $ , 26 mm. ; J , 27—31 mm. The lateral claspers of the 

 male spoon-shaped, widened in the middle, tapering outwardly, 

 and rounded at the apex ; the uncus doiible, the two points parallel, 

 shorter and wider apart than in arizonellus. 



Hah. One male and five females from Arizona, 

 collected by Morrison. 



This species has much the appearance of arizonella, 

 Wlsm., but the peculiar form of the antennae in the 

 male at once serves to distinguish it. 



Felderia cossoides, Eog. (PI. VIII., fig. 23). 

 Feld. and Eog., Nov., t. exxxix., f. 35. 



A single specimen of this species in Zeller's collection 

 is in poor condition, scarcely admitting of any descrip- 

 tion of the markings. No description is published with 

 the figure, the only remark made being " Pinaris hami- 

 ferella, Hb., Zutr., 441, etiam hujus generis esse videtur." 

 The figure represents a not very dark reddish brown 

 species with hind wings approximately the same colour 

 as the fore wings, with a dark spot on the end of the 

 cell, and another before and below it lying above the 

 commencement of the outer third of the fold ; there is 

 also a series of small darkish spots around the costal 

 and apical margins, the palpi rather paler than the 

 wings, and the antennae obviously pectinate. 



In all these particulars Zeller's specimen may fairly
