64 FOSSIL BUTTERFLIES. 



superior branches; the first arising shortly before the middle of the outer half of 

 the cell, a little nearer the apex of the cell in the female than in the male; the sec- 

 ond arising scarcely (male), or a very little (female), beyond the tip of the cell; 

 the third emitted at about two-fifths the distance from the apex of the cell to the 

 outer margin, forked at the extreme tip in the male. Cell half as long as the 

 wing and nearly four times as long as broad. 



The butterflies are scarcely larger than those of the genus Pieris, but have 

 more pointed fore wings; like them they are white, but extensively spotted with 

 deep brown; the fore wings have a broad bar at the tip of the cell, and midway 

 between this and the outer border a widely interrupted transverse series of similar 

 but smaller spots; the outer border, especially the upper half, is also more or less 

 distinctly margined with triangular, frequently confluent spots seated in the intei*- 

 spaces ; these occur more often in the female than in the male. 



The characters given above are drawn wholly from recent species of the 



PONTIA FREYEUI (Heer) Scuddkk.

The original description of this insect we owe to Heer; it is as follows: '

Das Geader ist nicht in seinem Yerlauf zu ermitteln und da auch der Umriss 

 des FMgels nicht vollstiindig vorliegt, ist die Gattung nicht mit Sicherheit zu 

 ermitteln. In Form und Farbe scheint er am meisten mit manchen Pieriden, 

 namentlich Pieris Daplidice, zu stimmen, wofiir auch das dunne Schuppenkleid, 

 das er gehabt zu haben scheint, angefuhrt werden kann, wogegen die allerdings 

 stumpfen Zacken am Ilinterrand cine abweichende Bildung zeigen.
