COLIATES. 51 



the fossil was drawn up from the illustration and not from the fossil itself. Both 

 agree in the points in which my drawing (PI. II, fig. 7) differs from them; and 

 since in these very points they will not harmonize with the neuration of any living 

 Lepidoptera, while the drawing I present agrees as well as could be desired with 

 certain of them, I am forced to believe the original drawing published by Heer, 

 and the accompanying description, presumably founded upon it, to be incorrect. 

 I am acquainted with but very few living butterflies 1 in which a nervule is emitted 

 from the inferior side of the subcostal nervure nearer the base of the wing than 

 any of the superior nervules of the same vein; this is the manner in which the 

 neuration of this butterfly is represented in Heer's plate and in his description, if 

 read carefully in connection with the plate ; although he does not tell us on which 

 side of his zweite Ilauptast his dritte Ilauptast originates. 



The description given by Heer of the markings of the fore wing is more 

 complete than I have been able to offer from an inspection of drawings alone; it 

 differs, too, in one somewhat important point, in that what I have called a broad 

 lighter belt with blackish dots in each interspace, he has described as a series 

 of pale circular spots as broad as the interspaces, each containing a blackish pupil. 

 A reexamination of the fossil upon this point is desirable; the only indication of 

 such circular pale spots in my drawing is the curved boundary in each interspace 

 between the darker and lighter portions.

The fore wing (PI. II, fig. 5) is slightly more than twice as long as broad; 

 the costal border is straight for fully two-thirds its length, and then curves grad- 

 ually and slightly downward, the apex rounded off; the outer margin has a nearly 

 regular and slight convexity, but is nearly straight in the middle half; the lower 

 outer angle is rounded and the inner margin slightly convex. The costal nervure 



'Those, it is true, arc Durcal, but aberrant forms, like Leptidia, etc.
