genera Acrolophus and Anaphora. 158 



Acrolophus arizonellus, n. s. (PL VII., fig. 10). 



Palpi, $ , recurved, reaching beyond the middle of the thorax; 

 ? short, slightly upturned, but scarcely reaching more than the 

 length of the head beyond it. Antenna subochreons, rather 

 flattened, simple, having a very slight notched appearance owing 

 to the scales on the upper side being a little raised at the joints. 

 Head, thorax, and palpi pale brownish, with a slightly hoary 

 appearance from an admixture of grey hairs. Fore wings greyish 

 brown, sprinkled with dark brown scales ; the costal margin very 

 narrowly subochreous, with about six pairs of ill-defined dark 

 brown dots along it ; a conspicuous dark brown spot at the end of 

 the cell and another on the fold at one-third from the base ; below 

 this in one specimen is a pale patch ; the fringes slightly paler 

 than the wing, but mottled with brown ; under side pale brownish, 

 the margins narrowly greyish ochreous. Hind wings brown, with 

 pale tips to the fringes; under side pale brownish. Abdomen : the 

 long hairy clothing of the base of the abdomen above is pale 

 greyish ochreous, the abdomen itself inclining to brown ; lateral 

 claspers elongate, spoon-shaped, curved inwards, tending to form 

 a slight angle at their upper and outward extremity; the uncus 

 double, with the two points very slightly diverging and not widely 

 separated. Exp. al. $ , 25 mm. ; ? , 86 mm. 



I have a male and two females from Arizona, collected 

 by the late Mr. Morrison.

"Intermediate in size between P. hamiferella, Hiibn., Zutr., 

 441, and scardina, Zell., but may be at once distinguished from 

 both by the ground colour of the wings. Antennae ochreous 

 (lehmgelb), palpi ochreous, the basal and middle joints dark brown 

 at the sides. Head and thorax reddish ochreous, upper side of the 

 abdomen dark umber-brown, under surface and pectus light 

 ochreous; front legs dark brown on the outside and pale yellow on 

 the inside ; middle legs pale yellow, the tarsi dark brown on the 

 outside ; hind legs pale yellow, the tibiae dark brown on the outside, 

 and the tarsi spotted with brown on the outside. Fore wings
