Plate I.

Fig.1.Eugonia atava. Copied from Heer, Insekt. Tert. Œning., ii, pl. xiv, fig. 8 (1/1).
2.Lethites Reynesii. Drawn by S. H. Scudder (1/1).
3.Eugonia atava. Copied from Charpentier, Nov. Act. Leop.-Carol., xx, pl. xxii, fig. 4 (1/1).
4.Eugonia j.-album. Neuration of fore wing; drawn by S. H. Scudder (1/1). The second superior subcostal nervule is carried too far toward the tip of the wing.
5.Lethites Reynesii. Fore wing; drawn by S. H. Scudder (2/1).
6.Eugonia j.-album. Markings of the upper surface of the fore wing; drawn by S. H. Scudder (1/1).
7.Eugonia atava. Neuration of tip of fore wing (2/1); copied from Heer; Insekt. Tert. Œning., ii, pl. xiv, fig. 3a.
8.Neorinopis sepulta. Markings of the upper surface of the two wings, restored; drawn by S. H. Scudder (2/1). The drawing represents the general effect of the fore wing as darker than the hind wing, and in so far is inaccurate.
9.The same. Neuration of the two wings, separated; drawn by S. H. Scudder (2/1).
10.The same. Neuration of the two wings, as seen in the fossil; drawn by S. H. Scudder (2/1). The engraver has unfortunately made the lines of the hind wing the heavier, as if it lay uppermost; they should have been the lighter.
11.The same. Right hind leg; drawn by S. H. Scudder (2/1).
12.The same. Left hind leg; drawn by S. H. Scudder (2/1).
13.The same. Drawn by S. H. Scudder (1/1). The spot of the medio-submedian interspace of the fore wings has not been well rendered by the engraver.
14.The same. Copied from Lefebvre, Ann. Soc. Ent. France [2], ix, pl. iii, II, fig. A (1/1).
15.The same. Copied from the same, fig. C (1/1).
16.The same. Copied from the same, fig. B (1/1).
17.The same. Copied from Boisduval, Ann. Soc. Ent. Fr., ix, pl. 8 (1/1).
