SCUDDER ON TERTIARY INSECTS. 525 



across the wing at right angles to the costal border, just failing to reach 

 either margin, divided by every nerviile,rits inner margin continuous 

 and nearly straight, its outer strongly crenulate, being gently convex 

 n the discoidal cell (more below than above), strongly convex in the 

 ower median and submedio-internal interspaces, and strongly sinuous in 

 the medio-submedian interspace; its upper extremity is before the mid- 

 dle of the wing, and incloses in its middle the base of the first superior 

 subcostal nervule; its outer border is bent inward below the cell, ex- 

 actly, to the last divarication of the median nervure, and it reaches the 

 anal area of the wing two-thirds the distance from the base. A row of 

 five unequal pale spots crosses the wing in a straight line, extending 

 from the lower outer angle to the costal margin at two-thirds the distance 

 from the base; four of these are approximated in' the subcostal inter- 

 spaces; the fifth and largest is in the middle of the upper median 

 interspace, but nearer the middle than the upper median nervule; it is 

 broadly ovate and obliquely placed, subparallel to the mesial baud, its 

 broader extremity above; the lower of the subcostal spots, before the 

 middle of the lowest subcostal interspace, is obovate, still more oblique, 

 pointing toward the upper of the subcosto-median spots to be mentioned, 

 and only a little smaller than the median spot. The three spots above 

 this are equal, about half as large as the previous, twice as long as 

 broad, rounded, subquadrate, each occupying nearly the entire breadth 

 of the subcostal interspaces next succeeding; the upper two appear as 

 a single spot, being scarcely divided by the intervening third superior 

 t^'ubcostal nervule. Still nearer the outer margin of the wing, and par- 

 allel to the row of spots just mentioned, are two subequal, rounded, 

 obovate spots, slightly broader than long, the upper a little the larger, 

 together occupying the entire breadth of the subcosto-median interspace, 

 removed by less than twice their width from the row of spots previously 

 mentioned; the fringe of the wing appears to be slightly darker than 

 the ground-color. 



Hind wings with a very large pale spot occupying the entire upper 

 outer angle of the wing, reaching from the outer margin nearly half- 

 way to the base, and from the costal margin to the upper median ner- 

 vule; its basal margin is convex in the subcosto-median interspace, fol- 

 lowing what would perhaps naturally be the outer limits of the cell, while 

 on either side of the lowest subcostal nervule the spot is separated from 

 the outer margin of the wing by a narrow dark edging. Un the irreg- 

 ular border which faces the median nervure, this pale spot emits three 

 long, more or less sinuous tongues of pale color: one a very narrow, 

 nearly straight, stripe or line along the margin itself, which only extends 

 to the elongated upper median nervule, the breadth of the spot being 

 less toward the margin than in the middle of the wing; a second, sub- 

 parallel to the outer border, and therefore arcuate, as well as slightly 

 sinuous, subequal, more or less broken into transverse spots, extending 

 to the inner margin, and distant, beyond the middle median nervule,
