silver-white postmedial dots, the three middle ones much farther out than the 

 others; rarely, with markings obsolete. Hind wing a little duller, usually immacu- 

 late. 25 mm. 



July. 



The two varieties overlap widely and intergrade. Westward the species seems 

 also to intergrade with D. fracturalis. 



Generally distributed, north to New Hampshire and Wyoming. New York : 

 Albany, New Windsor, Poughkeepsie, Crugers, Pearl River, Clove Valley, (Staten 

 Island) East New York (Long Island). 



2. D. talis Grote. Crimson; median area translucent yellow, divided by a 

 squarish crimson spot over the end of the cell, reaching the costa, and also touch- 

 ing the crimson base at the costa. A minute, hyaline antemedial spot. Hind 

 wing with the crimson confined to the base; a small quadrate spot on end of cell, 

 only a third way out, touching the basal crimson area, and a broa'd irregular 

 border. 18 mm.

Virginia; south to the tropics. 



21. BLEPHAR0MA8TIX Lederer 



(Nacoleia, in part; Lamprosema, in' part) 



Typically with male antennae simple and ciliate, smooth in B. rivulalis; front 

 somewhat rounded out; palpi trapezoidal, beak-like, the third segment lying along 

 the upper surface of the second, or somewhat prominent, obliquely divided in two 

 colors by a line running to the tip of the tuft; maxillary palpi slender, slightly 

 truncate at tip when perfectly fresh, extending to the tip of the upper surface of 

 the second joint of the labials. Fore wing fully twice as long as wide, with marked 

 apex and anal angle, and even, slightly excurved outer margin. Venation normal 

 ( fig. 322 ) , R 5 divergent from R 3+4 . Hind wing with all veins divergent. 



Ranalis is our only typical species. Magualis and rivulalis are transitional to 

 Lygropia; stenialis is apparently a Nymphuline, near Nymphula, but R 2 is con- 

 stantly free and it is usually placed in Blepharomastix.

1. B. ranalis Guenee. Clay-color, occasionally light brown, especially. in western 

 specimens ; markings darker dull brown ; costa shaded with brown ; antemedial line 

 excurved, often followed by a dark dash (claviform) in fold; orbicular a well- 

 marked ring; reniform a double bar or oblong outline; postmedial line in male 

 normally of two parts, the upper part running straight from the costa to the outer 

 margin at Cu 2 , the inner from the discal dot to the anal angle; the two sectors 

 sometimes connected by a line along Cu 2 . Female normally with a continuous line, 

 strongly sinuate on Cu 2 . A broken brown terminal line. Hind wing similar, with 

 a single dark discal bar. 20 mm.
