lar terminal dots. Tliere is a broad, obliijue, somewhat diffuse median 

 shade. Oibicular small, round, yellow. Eeiiif'orm upii<;ht, narrow, 

 yellow, with black dots at each extremity, sometimes couuected by a 

 dark line. Secondaries varying- from pale yellowish gray to almost 

 black, with a vague dusky median and pale subterminal line and a 

 series of blackish termiiuil lunulcs. Beneath more coarsely powdery; 

 all wings with a discal luuule, a broad, <'omnu)n, ]>ro\vn median line, a 

 pale subtermiiuil line, and a series of dark terminal lunules. 



Expanse of wings, 3.) to 40 nun. = l..'>2 to 1.00 inches. 



Habitat. — Canada to Virginia; Central States; New York and Dela- 

 ware in July; District of Columbia in August. 



The above description apjdies to an evenly colored specimen in which 

 all the maculation is Well defined: but as a matter of fact such speci- 

 mens are the exception rather than the rule. \'ery pale and very dark 

 specimens teiul to an obsolescence of all nuiculation, and only inter- 

 mediate forms are apt to have it evenly defined. Besides this range of 

 variation in evenly colored forms, there is a decided teiulency, equally 

 marked in both sexes in my experience, toward discoloration. The 

 median space maybe dark ami all else contrasting pale, or the opposite 

 maybe the case, or only one space may be affected, and this is as likely 

 to be the basal as tlie terminal. Yet, withal, the character of the 

 species changes little, and its size alone will serve for its recognition. 

 In the male the palpi are curved; the vestiture of the middle joint is 

 therefore longer at the middle than at the base, while in the female the 

 palpi are straight and the scales are even. 



The species is quite widely distributed and is not rare. The 

 sexual modifications offer nothing out of the common. 



Renia fraternalis, uew species. 



Ground color in the male a pale luteous gray; in the female yellowish 

 red-brown. Head and thorax concolorous with primaries. Primaries 

 in the male with the maculation fairly well marked; in the female the 

 subterminal line only is defined in most instances. Basal line indicated 

 on the costa. Transverse anterior line single, blackish, irregularly 

 outcurved, and outwardly exserted in the interspaces. Transverse 

 l)Osterior line finely crenulated, often punctiform, black, nearly parallel 

 with the outer margin, or only a little sinuated. Subterminal line punc- 

 tiform, a little outwardly bent about tlie middle, consisting of whitish 

 dots set in a more or less marked lead colored or black shading. A 

 series of black terminal dots or marks. A rather nairow, indefined, 

 median shade line, visible only below the median vein. Orbicular a 

 small yellow dot. lleniform narrow, ui)right, yellow, with a black dot 

 at each extremity. Secondaries sonunvhat jialer than i)rimaries, with 

 a dusky median line and a pale subterminal line, which is sometimes 

 absorbed in a darker shading which i)recedes it. Beneath more 

 powdery; both wings with discal spots, a usually distinct dusky median 

 line, and an (often Avanting) pale subterminal line.
