same median region is another subquadrate spot in the chivus seated on the 

 margin and generally limited interiorly by the anal vein, along which it 

 mav send shoots in either direction ; at equal and not great distances from 

 the apical margin is another pair of transverse subquadrangular spots close 

 to but not fairly seated upon the costal margin and sutura clavi, which are 

 sometimes connected by a narrow fringing band which hugs the apical 

 margin, though this band is sometimes reduced to an apical cloud which 

 barely reaches the spots on either side. The spots may thus be designated as 

 basal, subbasal, median (costo-median, suturo-median, and clavo-median), 

 subapical, and apical. The neuration of the tegmina can rarely be distin- 

 guished except in the most general way as regards the main veins, but 

 where the markings are most obscure, as in specimens which have some- 

 what of a bleached appearance, the minor neuration of the apex of the 

 wings can be discovered faintly.

In this species, the only one yet found elsewhere than at Florissant, 

 the markings of the tegmina are much the same as in P. maculata, but are 

 somewhat reduced, and, what is more remarkable, the subbasal spot is ab- 

 sent ; this point seems to be sufficiently clear, though the outspread teg- 

 mina are preserved in a fragmentary manner, curiously most perfect just 

 where the spots occur, as though the pigment bore some part in their pres- 

 ervation No veins are visible.

This species is remarkable for the great distinctness with which ordi- 

 narily (the considerable distinctness invariably) the complete neuration of 

 the apical half of the wing is seen, as de.scnbed niidcr the genus. The
