1 63] ON SOME SPECIES OF NISONIADES. 175 



The spots " beyond the median nerve " vary in size and in 

 number in the same species, as will readily be seen by an 

 inspection of a number of individuals. In two of the above 

 examples of N. tristis, there is a white spot in each of the 

 cells 2 and 3 ; in the third, in cell 3 only. When but one spot 

 is present, it is always that in cell 3, the smaller of the 

 two having disappeared. Nor does the number of anteapical 

 white spots afford a specific character, for while the normal 

 number is four, some examples of N. Marticilis in my collec- 

 tion show but three, and others (more rarely) five. 



Nisoniades Afranius n. sp. 



Thorax and abdomen above, black ; beneath, with brown 

 hairs. Palpi clothed with long brown hairs. Legs fuscous. 



Primaries with the costal margin nearly as straight as in 

 N. Persius, but rounded toward the apex ; moderately bent 

 basally. Outer margin more rounded than in any $ Nisoni- 

 ades known to me (the $ ' s, as a rule, having more rounded 

 wings), as much so as in N. Brizo ? . Inner angle rounded, 

 with internal margin short. 



The usual black markings in the basal region of the wing ; 

 the remainder clouded with brown, distinctly relieving the 

 transverse line of elongated black spots, and the row of 

 rounded submarginal black spots ; a few gray scales are 

 sprinkled over the brown ground. The black spots of the 

 transverse band above vein 2 are more elongated in proportion 

 to their width, more acute toward the outer margin, and more 

 sharply defined than in any other known species even than 

 in N. Ausonius. The line of four small, anteapical, white, 

 hyaline spots is sensibly drawn inward toward the base, so 

 that an imaginary line traversing these spots will cut the outer 

 margin within its apical half. A white hyaline spot rests on 

 the black spot in cell 3, and the three black spots in cells 2 

 and 1 b, have some gray scales centrally. There is a trace of 

 a small, whitish, hyaline, discal spot. The terminal margin 

 is without the black line seen in N. Martialis. 



Secondaries, dark umber-brown, with the two rows of pale 

 brown spots, similar to those of N. Persius ? . 



Wings beneath, a rich umber-brown, showing on the prim- 

 aries the discal and anteapical spots more plainly than above, 

 and a white spot each in cells 3 and 2. The two rows of pale 

 brown spots on the secondaries are strongly relieved by the
