E^TOHOLOQICAL CONTRIBUTIONS. 171 



Fringe squamose, long, equal in length to the space between veins 

 2 and 3 on the margin ; basal third brown, and a narrow brown 

 line through its middle ; outer scales clavate, and, under a lens, 

 white, centered with pale brown. 



Secondaries abruptly rounding into the apex, which is slightly 

 acute, less so than in asteroides ; outer margin convex, excavate 

 between the subdorsal and median nervules and prominently angu- 

 late on the submedian ; in the male, white, hyaline, with a lustrous 

 brown border, shading paler from the margin inwardly, broadest 

 apically where it occupies one-sixth of the length of the wing, nar- 

 rowing regularly to the internal angle, and terminating between the 

 submedian and internal nervures. The subdorsal and median nerves 

 and nervules with brown scales, which almost cover the nervules, 

 especially in the subterminal region ; the submedian with a marginal 

 spot of a few brown scales. Fringe white, with a few pale brown 

 scales on the superior half of the wing. In the female, wing whitish 

 (smoky-white) basally and slightly hyaline ; border a lustrous brown, 

 of not quite so dark a shade as in asteroides^ broader than in that 

 species, about equal to intermedia^ occupying nearly one-third of the 

 wing apically, its inner margin tolerably well defined, and is con- 

 tinued indistinctly along the internal nervure nearly to the base : 

 costal region also shaded with brown above the s. c. nervure and 

 extending into the cell in the basilar region. The submedian and 

 its branches more heavily clothed with brown scales than in the 6 • 

 Fringe white, traversed with brown in its superior half. 



Beneath, primaries lustrous pale brown, the costa gray basally, 

 the $ with ochreous hairs supporting the frenulum. Secondaries 

 without the discal spot, which is also lacking in asteroides^ evident 

 in asteris and conspicuous in itmhratica^ lucifuga and intermedia i 

 white in the ^ with brown scales in the costal and apical region and 

 a few on the terminal margin ; the terminal and subterminal regions 

 give a creamy reflection in a certain light. In the ? , more nume- 

 rous brown scales costally, and with a lustrous brown border nearly 

 as broad and as prominent as on the upper surface, traversed by the 

 paler nervules. 



Expanse of wings of $> , 1.98 in. ; of ? , 2.07 in. Length of body, 

 including anal tuft of (5 , 1 in. ; of ? , .95 in. 



I take pleasure in naming this species after Dr. Speyer, in recog- 

 nition of the study that he has bestowed on the perj)lexing species of
