250 THE CANADIAN ENTOMOLOGIST. 



1265. Polia pulverulenta, Smith. One. 



I may mention here that the Polias I have hitherto sent 

 to my friends as confragosa belong, Dr. Smith now 

 says, to the medialis-aactissima species, the oiie 

 being a variety of the other, 

 1650. Euxoa incubata, Smith. One, the first taken. 



In Spiiingid?e, Bombyces, Geometridae and Micros, I 

 took practically nothing at all, owing, I suppose, to 

 the unfavourable weather for collecting at lights. 



GEOMETRID^ AS YET UNDESCRIBED. 



BY RICHARD F. PEARSALL, BROOKLYN, N. Y. 



Chlorosea Froutaria, n. sp. — Expanse, 32-34 mm. Antennae bipect- 

 inate in ^ , serrate in $ , white above, yellowish beneath. Front and 

 vertex rosy white, the border of orbits and a line behind vertex in ^ 

 deep roseate. Wings of the same thin texture, size and shape as 

 Nevadaria Pack, but the green of primaries is more intense, and the 

 strigations of white a little more marked, especially in the ^ . An almost 

 straight broad white line crosses primaries, starting from costa about one- 

 fourth from apex, and sloping more strongly toward base, than does the 

 same line in Nevadaria. reaches inner margin at centre. There can be 

 traced a very faint suggestion of a narrow white basal line in both types, 

 more evident in the $ , one-fourth from base at costa, and rounding out- 

 ward to same distance on inner margin. Secondaries in $ white silken, 

 tinged at anal angle with green, and having marginal line of same colour ; 

 fringes short, white. In ^ they are white, centrally traversed by a white 

 curved line, parallel to outer margin, not defined costally, quite evident 

 at inner margin, where it curves strongly toward base. Within this line 

 there is a thin dusting of green scales ; outside it, they are heavily scat- 

 tered, becoming intense and strigate toward anal angle : marginal line and 

 fringes green. Beneath all wings an even greenish white, the outer line 

 of primaries showing through faintly. No discal dots above or below. 

 Thorax and basal segments of abdomen above pea green, the latter white 

 terminally and beneath. Body beneath white, washed heavily in front 

 and faintly at sides with green. All legs with femora green, the front pair 

 with tibiae roseate, all others white ; all tarsi white. 



Types rt ^i^d ? , the former taken at Chimney Gulch Golden, Col., 



VIII, 26, '04 (Oslar), the latter at Eureka, Utah, V, 27, '10 (Spalding), in 



author's collection. In appearance much like Nevadaria Pack, but easily 



distinguished from it by the absence of red markings on abdomen.
