AMERICAN LEPIDOPTEItA. 25 



quarters of their length when they are provided with a long dense and 

 rigid tuft of hair, beyond this they are slender and curled. The fe- 

 male antennae are simple, and in both sexes relatively short. The 

 male palpi have the seeond joint disproportionally elongated, fringed 

 with long scales above, and are porrected ; the female palpi are pro- 

 jected straightly forward after the fashion of Hypena, except in E. re- 

 strictalis. The structure of the palpi however varies slightly with the 

 species. The male R. discoloralis has the primaries above of a clear 

 brown, more or less pale owing to ah admixture of light colored scales 

 giving the wings in some specimens a powdery appearance. The t. a. 

 line is narrow, thrice unequally waved. Median shade diffusely 

 shaded, of Varying distinctness, oblique. T. p. line inwardly lunulate, 

 irregular, obsoletely geminate, the outer line hardly discernible and 

 the line itself often obliterate. Orbicular small, usually distinct, 

 rounded, pale yellowish. Reniform narrow, subluniform, clear pale 

 yellowish or ochrey with an upper and lower black included dot; often 

 these dots are connected by a middle line. Sub-terminal line dis- 

 tinct, geminate, with pale included shade, broken opposite the cell, 

 projected on vein 4, again broken or indistinct below vein 3. A ter- 

 minal line of interspaceal black points. Secondaries dark, crossed by 

 two distinct lines. The male antennae are tolerably long from the base 

 to the tuft. The long palpi porrect. 



The female is usually discolorous. The sub-basal, sub-terminal and 

 terminal fields of the primaries above are paler than the rest of the 

 wing and give it a blotchy appearance. The color varies considerably. 

 One specimen from Virginia is evenly ochrey griseous and has the or- 

 dinary spots deep yellow while the wing, thorax and head is more or 

 less sprinkled or stained with deep yellow scales. The shorter anten- 

 nae are simple ; the labial palpi projected straightly forward, equally 

 as long as in the the male, terminal joints divaricate. One specimen 

 resembles the $ in color but the primaries are more profusely pow- 

 dered with pale scales. Expanse 35 to 40 mm. 



Habitat. — New York, Pennsylvania, West Virginia, Virginia. 



Not rare. Mr. Walker's Hypena fallacialis is a synonym. In the 

 British Museum Collection the most discordant material has been ar- 

 ranged under Hypena, and many of the descriptions in the List under 

 Hypena are of no value whatever. 



10. Renia brevirostralis, m.— % £ .—Pale oelirey or bone color. Male 

 antennae shorter altogether and particularly so from the base to the usual tuft, 

 compared with R. discoloralis. Female antennae simple. Male palpi porrect,
