PSYCHE. 



[September 1S93. 



the male are relatively short, heavily pectina- 

 ted, directed forward and then recurved about 

 the middle. The antennae of the female are 

 very minutely pectinated, appearing simple 

 to the naked eye. The primaries of the male 

 are broad, subtriangular, with the costa 

 strongly arched, the outer margin and the 

 outer angle evenly rounded, the inner margin 

 almost straight. The secondaries of the male 

 have the costa strongly produced upwardly 

 about the middle, giving the costa a lobed 

 appearance. The apex, the outer margin, 

 and the anal angle are evenly rounded. In 

 the female theprimaries are sharply produced 

 at the apex and subfalcate. The secondaries 

 have the costa as in the male sex. The 

 female is twice as large as the male. In both 

 sexes the discocellulars. of the primaries are 

 angulated; veins six and seven and nine and 

 ten are stalked. Vein eleven apparently 

 coalesces with twelve about its middle. 

 Twelve is continuous along the costal margin. 

 In the secondaries veins four and five are 

 stalked; veins six, seven, and eight diverge 

 widely, vein eight terminating at the extrem- 

 ity of the lobed projection of the costal 

 margin. Type L. peraffinis, Holland. 



Neuration of Leipoxais peraffinis, Holl., -f, i- 



172. L. peraffinis, sp. nov. $. Body and 

 appendages reddish-brown. Primaries and 

 secondaries of the same color as the body, 

 the secondaries inclining to luteous on the 

 inner margin and. the primaries shading on 

 the outer margin in many specimens into 

 cinereous. The primaries are ornamented 

 by a curved sub-basal obscurely blackish line 

 followed by a minute silvery white dot on 

 the cell, after which there are two irregularly 

 curved obscurely blackish transverse lines, 



which diverge on the costa and converge at 

 the middle of the inner margin. Beyond this 

 there is a sinuous band of small obscure 

 blackish sub-hastate spots extending from 

 before the apex to the outer third of the inner 

 margin. The secondaries on the upper side 

 have no markings. The primaries on the 

 under side are pale fuscous without markings 

 except that the transverse bands of the 

 upper side very faintly reappear on the lower 

 side in some specimens. The secondaries on 

 the under side are marked by a very sinuous 

 band of angulated spots extending from 

 before the apex irregularly parallel to the 

 outer margin as far as the first median 

 nervule. The lobe-like projection of the 

 costa is- clouded with dark fuliginous and a 

 similar fuliginous spot is located beyond the 

 the cell upon the median nervules not very 

 far from their origin. The inner margin is 

 pale stramineous. 



2- In the female the upper side is marked 

 very much as in the male, save that the 

 sinuous submarginal band of the primaries 

 is composed not of blackish, but of pale 

 whitish spots, and on the under side there is 

 a dark brown spot on the costa before the 

 apex accentuated outwardly by two whitish 

 dots, and the secondaries are crossed by a 

 very broad transverse median and a some- 

 what narrow transverse submarginal band of 

 dark reddish-brown. Both of these bands 

 terminate inwardly upon the first median 

 nervule. Expanse, $, 32 mm. ; $,56 mm. 



There is what appears to be a variety of 

 this species in which the space between the 

 two outermost transverse bands of the prim- 

 aries is paler than the body of the wing, 

 inclined to luteous, and in which the whole 

 median area of the secondaries on the upper 

 side is likewise pale. There is a very marked 

 resemblance in this species to the insect 

 described as Gastropaclia haematidea, Snell., 

 but the fringes in this species, of which a 

 suit of fifteen specimens is before me, are not 

 checkered as in the insect described by 

 Snellen, but are uniformly brown and the 

 markings are different in other respects.
