14 FOSSIL BUTTERFLIES. 



are two large patches of pale color in the upper half of the wing as in Neorinopis, 

 but the inner is much obscured by a dark bar crossing the middle ; and the outer in- 

 stead of the inner patch is connected with the lighter parts of the lower half of the 

 wing, and is separated from the parts within by a long line whose general course is 

 at right angles to the costal border; in the markings of the hind wings it is by no 

 means unlike Zoplioessa Sura (PI. II, fig. 3), and resembles less conspicuously 

 Debis Sinorix (PI. II, fig. 14), with which also it agrees admirably in the form 

 and neuration of the wing; in the shape of the tail particularly, and in the size of 

 the insect also, Xeorinopis agrees better with Deltis Sinorix than with any but- 

 terfly I have been able to examine. In neuration and in markings, although not 

 at all in the form of the wings, this fossil shows no distant alliance to our own 

 Enodia Portlandia. 



The other parts of the body are not sufficiently preserved to admit of their 

 use in generic description, if we except the hind legs ; these are slender, the tarsi 

 (which are barely shorter than the thorax) being of the same length as the tibiaB 

 and a very little longer than the femora.

The earliest notice of this fossil butterfly, the first species ever described 

 and illustrated, the most perfectly preserved and the best known to the world at 

 large, was given by Marcel de Serrcs in 1828, in the Annales des Sciences 

 Naturellcs; and in 1829 in his Geognosie des terrains tertiaires; where he simply 

 cites on the authority of some one else the occurrence in the beds of Aix of 

 a butterfly belonging to "la division des Satyrus."
