Packard.] 38 [May 7, 



middle of the wing and forming a large discal ring larger than in the 

 European Rumia crategata, and enclosing a pale dot; the line is a 

 little sinuate, and is often obsolete, es ecially in rubbed specimens, 

 leaving a distinct distal ring and costal spot just in front of it. An 

 outer very sinuate row of spots, often obsolete, except on the costa. 

 Wings brown. 



Hind wings paler than fore wings, with no markings, but a little 

 deeper ochreous towards the outer edge. Fringe concolorous with 

 the rest of the wing. 



Beneath on fore wings no lines or discal spot, but the outer costal 

 brown spot is present, and there are brownish costal spots within. 

 Hind wings same as above. Legs a little dusky at the femoro-tibial 

 joints ; tibia? a little dusky. 



Length of body d, .55, $, .50 inch ; of fore wing d, .72, ?, .62 inch. 

 1 d, 2 ?, Sierra Nevada, CaL, and Nevada (Edwards). 



Metrocampa virido-perlata n. sp. l d, 1 ?. 



More nearly allied to our eastern species than to the European, 

 but still it differs in the two bands on fore wing being nearer together, 

 the inner band crossing the base of the origin of the third median 

 venule. Antennas the same. 



Though the moths expand equally, yet in both sexes the head is 

 much smaller than in perlata, an unusual distinction, while in perlata 

 and margaritacea the head of the d (no ? of margaritacea for com- 

 parison) are of the same size. The Nevada species is also a little 

 greener than our species. Red band below antenna?, as in perlata. 



Until a large number of specimens are compared I shall consider 

 the species distinct, though they would be easily confounded at first. 



Length of body d, .50, ?, .60 inch; fore wing d, .77, ?, 1 inch. 



Sierra Nevada, CaL, (Edwards). 



Selidosema juturnaria Guen. 



Alaska (J. Behrens); Colorado Terr., (Ridings, Coll. Amer. Ent. 

 Soc). 



Tetracis parallelia n. sp. 



Allied in general form to T. truxaliata. The two outer subcostal 

 venules much shorter than in that species. A fresh specimen, though 

 smaller (length of fore wing .42), from Mr. Behrens, is ochreous, 

 though paler than in T. truxaliata, with deep reddish ochreous lines 

 on fore wings. Angle of hind wings well marked, though much less 

 distinct than in T. truxaliata.
