R. pulverosalis is obscurely marked, altogether more frail, with 

 longer palpi, more slender antenna', and more pointed primaries. Tiie 

 wings are entirely obscured by smoky powderings, and the markings 

 of the i)rimaries are traced with difdculty, while on the secondaries 

 they are often scarcely obvious. 



AXALYSIS OF TIIE SI'ECIKS OF liENIA. 



1. Palpi of male short, obli(iue; middle joint with a specialized tuft or l)rnsh of hair; 



terminal joint short salusalis. 



Palpi long in both sexes; without specialized tuft of hair; terminal joint at least 

 moderate 2. 



2. Transverse posterior line nmre or less denticulate, narrow, blackish, not accom- 



panie<l l»y a, pale shade, often obsolete or. barely traceable 3 



Transverse ]iosterior line pale, even, preceded by a narrow, evi'ii, dusky line .. 8. 



3. Primaries trigonate, with the apex somewhat produced acute; outer margin long, 



a little excavated below, and very obli(|U(; 4. 



Primaries shorter and broader; apex rectangular; outer margin not excavated, 

 shorter, and only a little oblique 7. 



4. Size large; subterminal line distinct, outwardly angulated at its middle, preceded 



or followed, or )>oth, by a dusky defining shade discoloralis. 



Size moderate or small; subterminal line punctiform, i)receded by variably dis- 

 tinct spots rather than shades 5.

Gronnd color Inteous, varying in shade, with black powderings. 

 Head and thorax concolorous. Primaries with the markings distinct 

 in the male, a little obscure in the female. Basal line punctiform, 

 traceable in the specimens before me. Transverse anterior line brown, 

 upright, or nearly so, a little irregular. Transverse posterior line 

 creuulated, rather evenly bisinuate as a whole, and very oblique, 

 nearly parallel with the outer margin. The line is sometimes reduced 

 to a series of venular dots. Subterminal line irregular, pale, obscure, 

 marked by blackish preceding spots varying in luimber and distinct- 

 ness, and sometimes followed by less evident marks of the same char- 

 acter. A series of black venulnr dots. A diffuse, oblique, brown 

 median shade becomes evident below the reuiform and often con-
