A REVISION OF THE DELTOID MOTHS SiMlTH. 73 



darker shade eini)liasizes tliesc dots. A series of blackisli teniiinal 

 lunules. Orbicular a small yellow dot, which is often wanting-. Jfeni- 

 forni ui)rioiit, narrow, yellow, with a small black dotateacli extremity. 

 Secondaries a little paler, with a median darker, an extramediau i)ale, 

 and an interrupted blackish terminal line. The subterminal line is 

 quite usually lost, sometimes marked by a darker shadinf?, which per- 

 sists when the line which it was meant to define has disappeared. 

 Beneath paler, the secondaries more grayish and coarsely powdered. 

 All wings with a discal spot, a rather broad, extra median dark shade 

 line, and a slender, whitish, subterminal line, which is sometimes a 

 little diffuse on the secondaries. 



Expanse of wings 23 to li5 mm, = 0,1)2 to 1 inch. 

 Habitat, — Kova Scotia to West Virginia; Central States; New York 

 and Washington, D. C, in August. 



This is a fairly well marked species, varying in depth of ground 

 color and in the relative indistinctness of the maculatioii. The body 

 structure is comparatively more robust, and the wnng form is less 

 extended apically than in the last preceding species. I can not find in 

 my specimens the sexual difference in the palpi described by Mr, Grote, 

 and think it probable that he had associated poor specimens of differ- 

 ent species as two sexes, an association which led to my suggestion' 

 that this was a small form of R. restrictalu. Good specimens of both 

 sexes make it certain that we have a good species in which the palpi 

 are alike in male and female, and are also more closely scaled than in 

 the other species; approaching TtianolitH very decidedly. The s[)ecies 

 does not seem to be common,

Ground color varying from luteous to leather brown, more or less 

 l)owdery, sometimes appearing smoky. Head and tliorax concolorous. 

 Primaries with the maciilation variably distinct, s<niietimes ol»scured, 

 more usually evident, sometimes contrasting. There is a decided ten- 

 dency to discoloiatinn. as in li. (iiscolortilis, ]mt U'ss strongly marked. 

 As a rule tin; dusky sliade ])re<'ediMg the subterminal line is the most 

 marked character. Uasal line evident in thecostal space. Transverse 

 anterior line distinct, sojnetimes prominent, even or slightly sinuate, 

 u])right or only a little bent or ohli(|ne. I'ransverse i)osterior line 

 irregular, even over the costal region, ineguhvrly crenulate, sometimes 

 l)unctiform below this point; as a whole nearly jtarallel witli the outer 

 margin. Subterminal line only a little paler than the ground color;
