This genus of the Ennominse {Gcoinctrince Prout, Selidosemidce 

 Meyrick) is a very singular one combining characters of Glancina 

 and Hulstina. 

 10. Cedaria ritaria, new species. 



Expanse, 20-25 mm. Head, palpi, thorax and abdomen with mixed brown 

 and white scales, sometimes one sometimes the other color predominating. 

 The brown scales of the abdomen occasionally collect into patches which are 

 arranged at the base of the segments. Primaries cinereous, more or less 

 overlaid with brown. Five brown lines somewhat diffuse and of moderate 

 breadth cross the wing obliquely. The first, sometimes obsolete, crosses at 

 inner fifth, is roundly bent outward below costa: and thence extends slightly 

 curved to base of inner margin. The second line crosses at inner fourth and 

 is nearly parallel to the first, but is slightly toothed outwardly on the anal 

 vein. The following two lines, crossing almost through the center, begin 

 widely apart on the costa, curve outwardly one-third across the wing, mean- 

 while converging, and then extend obliquely inward to center of inner margin, 

 curving outward again, however, before reaching that point. Immediately 

 following the outer of these two lines is a fifth line, usually more diffuse than 

 the others, and often broken in its course. The space between this and the 

 preceding line is filled in with ochreous, thojigh at the costal area this tint is 

 occasionally lost. Sometimes the line bordering this shade externally is lost. 

 A diffuse terminal shade is present running through the outer space. Ter- 

 minal line narrow, dark brown. Fringes checkered. Discal spot absent. 

 Secondaries almost wholly covered over with dark brown, the cinereous ground 

 showing as two or three obscure bands crossing the outer half of the wing, 

 most perceptible on the inner margin. Beneath, wholly cinereous or with 

 primaries smoky. A broad, brown band sometimes crosses the secondaries on 

 inner third in a straight line ; rarely this is continued very faintly across the 

 primaries. 



Types. — Two males and three females from Dr. Barnes. 



Habitat. — So. Arizona, April 1-15; Santa Catalina Mts., Pinal 

 Co., Aug. 1-7; Santa Rita Mts., Pima Co.; Baboquivaria Mts., Pima 

 Co., July 15-30 — all Arizona. 



A characteristic species which in a very general way may be 

 likened to a small Hulstina formosata Hulst.
