genera Acrolophus and Anaphora. 165 



Seven males from North Carolina, collected by 

 Morrison; there is also a single male in Zeller's 

 collection without locality. 



Anaphora macrogaster, n. s. (PL VIII., figs. 19, 19a). 

 Labial palpi, $ , recurved, reaching nearly to the posterior edge 

 of the thorax ; J erect, reaching somewhat ahove the elongate 

 basal joint of the antennae. Antenna: J , bipectinate, the pectina- 

 tions wider at their bases than outwardly, fringed with short hairs ; 

 suboclireous.; ? simple. Head, thorax, and palpi mottled greyish 

 and brownish fuscous. Fore wings brownish fuscous, slightly 

 mottled with paler along the costal and apical margins ; with an 

 elongate patch of dull whitish running irregularly along the length 

 of the fold ; a smaller spot of the same colour immediately beyond 

 the outer end of the cell. Hind wiiu/sbrown ; the fringes scarcely 

 paler. Abdomen the same colour as the hind wings, that of the 

 male about 7 mm., of female 10 mm. ; the lateral claspers of the 

 male spoon-shaped, scarcely inverted, dilated outwardly, but 

 tapering slightly upwards and rounded at the apex ; uncus double, 

 the points parallel and somewhat closely approximate. Exp. al. 

 J , 22 mm. ; ? , 29 mm. 



Three males and three females from Arizona, collected 

 by Morrison. 



Feldeeia, n. g. 

 Type. Acrolophus cossoides, F. & E. 

 Labial palpi overarching the thorax, roughly clothed with long 

 loose scales. Maxillary palpi 3-jointed, rather long- and slender. 

 A ntennce strongly bipectinate, the pectinations fringed with delicate 

 hairs. Fore wing, the form of the wings and neuration as in 

 Anaphora. Abdomen, lateral claspers of varying form, more or 

 less spoon-shaped.
