44 FOSSIL BUTTERFLIES. 



same in position, direction and intensity, as in .E. j-album (PL I, fig. 6). The 

 same may be said of the form of the wing, as far as it can be seen, but as this 

 is true only of the costal margin, and the merest fragment of the outer border, 

 it cannot be considered to have much weight in itself; still, taken in connec- 

 tion with all the other features, which agree almost wholly with those of Eugonia, 

 and but partially with its near ally Vanessa, to which Heer compares it, we must 

 refer the fossil to Eugonia, at least until a new examination of the fossil shall give 

 us further facts as a basis for an opinion. This is the position dubiously assigned 

 to it by Kirby, in his Synonymic Catalogue.

Of the form of the fore wing (PI. II, figs. 7, 17) we can say but little, from 

 the imperfect nature of the fossil; the costal margin, however, is very regularly 

 and rather strongly arched, and the direction of the middle portion of the outer 

 border (probably at a right angle, or at a little less than a right angle, with the 

 apical portion of the costal margin, and but slightly convex) leads us to presume 

 that the apex was rather pointed, though not falciform. 



The neuration of the same wing (PI. II, fig. 7) is very similar to that of 

 Mylothris. 1 The costal nervure terminates at about five-sevenths the distance 

 from the base of the costal margin to its tip; the subcostal nervure emits two 

 branches before the cell, the second probably close to the apex of the cell, the 

 limits of which are not given in the drawing prepared for me, but which could 

 probably be made out by a sufficiently careful examination of the original; a third 

 superior nervule is emitted from the subcostal nervure at less than half the dis- 

 tance from the origin of the second to the outer border, and the emission of the 

 inferior nervule, if it could be traced, would mark the termination of the cell; the 

 median nervure is of course three-branched and scarcely curves upward at all 

 to meet the subcostal.
