Pieris Nasturtii, Boisduval, in lit. 
Male. Expands ly^^ inch. Upper side white primaries as in Pro- 
todlce ; a rhomboidal black spot upon the arc; three sub-marginal 
spots in line, and several acute spots on the apical half of the hind 
margin. 
Secondaries have a few black scales near outer angle and at the ex¬ 
tremities of the nervules; owing to the transparency of the wing the 
grey tint of the nervules and lines of under surface are distinctly 
visible. . 
Under side of primaries like the upper, the spots less distinct; apex 
greyish. 
Secondaries have a broad, serrate, sub-marginal band of grey scales, 
the points extended to the.margin; all the nervures about the base 
and cell heavily bordered by grey scales. 
Female. Expands 2yL inch. Wings more delicate, the white less 
pure, *a violaceous tinge at the base; the spots as in female Protodice., 
but of a faint coppery hue. 
Under side of primaries with spots as above, but less distinct; the 
apex yellowish. 
Secondaries yellowish; the nervures all bordered by ochrey scales; 
the sub-marginal band almost obsolete. 
San Francisco; from Dr. Behr, who informs me that it is common 
in some localities in the vicinity of that city. P. Protodice seems also 
not uncommon. 
Pieris vernalis, nov. sp. 
Male. Expands ly'^^ inch. Upper side white, less pure than in Pro- 
todlce ; primaries have the costa and apical nervules edged with black¬ 
ish brown; the sub-marginal band is obsolete, or indicated by a few 
dark scales only; up^n the arc a rhomboidal bar.
