feebly (l«^iiti(*ulate ; in course, bisiiuiate. oiitcnrved over the cell, incurved 

 beiicatli. Snbtennnial line riyid, pale, i)recede(l by a brown shade 

 which is nnvardly dittiise. A series of black, venular, terminal dots. 

 Orbicular wanting. Reniforni a very obscure dusky lunule, which is 

 sometimes barely traceable. Secondaries more powdery and somewhat 

 paler than primaries, with an obscure dusky extra median line and a 

 more evident, sometimes even well-maiked, pale subterminal line. 

 There is also a slender dark terminal line, followed by a yellowish line 

 at the base of tlie fringes, and occasionally a vague discal lunule. 

 Beneath, more gray and quite coarsely powdery. All wings with a 

 discal spot, a well nuirked extra median line, and a variably distinct 

 l)ale subterminal line, which is more frequentl}' wanting- on the pri- 

 maries. 



Expanse of wings, 1*1 to 1*5 mm. = 0.84 to 1 inch. 



Habitat. — New York to Alabama; District of Columbia, in August. 



This, so far as the specimens before me indicate, is a very constant 

 species, liable to be confused with Z. cruralis and Z. minimally. From 

 the latter it differs in the rigid transverse anterior line; from the former 

 in the purplish ground color and generally obscure maculation, the 

 transverse posterior line tending- to become obsolete, while it is usually 

 somewhat irregularly, though feebly, denticulated. The subterminal 

 line is preceded by a brown shade, rather than a line, and these char- 

 acters, with the decidedly smaller average size will enable the species 

 to be recognized in most instances. Most of the specimens before me 

 are from the United States National Museum, '' collection C. V. Riley," 

 and bear his record number, 2807, and dates ranging from August 7 

 to 17. 



In the structure of the male antenuie and fore legs tliis species resem- 

 bles Z. cruralis closely, and in the latter character indeed no essential 

 difference has been noted. The characters of the antenna' are some- 

 what ntensified, however — that is, the bend is more marked, the joints 

 beyond more slender, while the corneous processes are heavier, and a 

 third joint is often involved, also furnished Avith a process. Otherwise 

 no notable difference has l)een made out.

Ground color varying from luteous to ])urplish smoky brown. Head 

 and thorax concoloroiis. Primaries with all the maculation usually 

 obscure. Uasal line traceable on the costa in some specimens, usually 

 obsolete. Transverse anterior line slender, brown, evenly but not 

 strongly outcurved, with moderate outward angulations between the
