36 GROTE—THE DESCENT OF THE PIERIDS. [Jan. 5, 
position; in Cunzzza, as in Hespferocharts, only Kr remains in posi- 
tion (as in Piccarda-Delias), and R2 and #3 are short apical 
branches, succeeding each other out of #4 -++ 5, the Anthocharid 
type. The resemblances between Cumizza and Hesperocharis are 
too great to be set down to convergence, unless we had other char- 
acters. Again, the humeral spur sets toward the apex in Perrhy- 
éris, the Pierine position ; in Cumzza it curves in the opposite 
direction, and this seems to be its trend in Hesferocharis, in which 
it is truncated. Alone the shape of the wings tend to remove 
Cunizza from the Hesperocharis and to bring it over to Perrhydris. 
Independent of the fact that the shape of the wings may be also 
influenced, the resemblance to Perrhyéris is by no means exact. 
The apices are bluntly rounded, produced, in Cunzzza ; in Perrhy- 
éris, though rounded at apices, they bulge between J/2 and 173, 
just where they retreat in Cwnzzza. The latter differs strongly 
from Hesperocharis, where the apices are squared and the external 
margin descends straightly. 
A broken line, which may connect with the main line of Pverts, 
seems to be indicated by the North American Pine Tree White: 
Neophasia menapia Felder. It is possible, also, that JVeophasza 
is a generalized form of Pyrsrhydris.

Type: N. menapia. 
Neophasita menapia. 
Wings somewhat elongated and shaped asin Deéas, but frail in 
texture, and in this character resembling Leffostza. The Prerts 
type of neuration is nearly repeated. Radius four-branched ; £2 
moved forward, but not attaining cross-vein; the fork of £3 
longer than in Pveris. Cell closed, the vein between J/2 and 473 
hardly degenerate ; 4/2 radial; J/1 ascending radius and leaving 
it about at one-third of total distance from tip of wing. Second- 
aries with humeral spur turned inwardly at tip, somewhat obscure 
and truncate ; Sc. appearing undivided at base.

of this insect. Through anapparent confusion of localities, the German lepidop-. 
terist Fruhstorfer thought he recognized, in a Pierid flying about meadows in the 
vicinity of Washington, D.C., this insect, which inhabits Washington Territory 
and Idaho. See /usehten Borse, Nov. 16, 99, p. 279.
