black point, near the middle. The under wing’s are without any 
spots, but are bordered behind by a cinereous thread. The under 
side of the upper wings have the costa and summit covered with 
spots and minute incontinuous lines of a yellowish colour. The 
underside of the lower wings are sulphureous, with very line un- 
dulating or rather incontinuous lines of a yellowish colour. 
The species has been named by Captain King, after John Wilson 
Croker, Esq., M.P., and first secretary to the Admiralty. 
138. PiERis Niseia, (n. s.) P. alis albis limbo late nigro ; an-

subtus nigro-venosis limbi maculis luteo-notatis. 
Obs. This insect comes very near to the P. Teutonia of Godart 
and Donovan, particularly in its under side. It is, however, smaller 
than that insect. The upper wings are white, with a posterior 
broad black subtriangular border, having two or three white spots 
at the apex. These wings have a black spot near their middle, 
which is also on the under side, but there communicates by a trans- 
verse, short, and rather curved, black band, with a black superior 
edging of the wing. In other respects the under side of the su- 
perior wings is like the upper, except perhaps that it is yellowish 
at the base. The lower wings have their upper side white, with a 
broad black border. Their under side is strongly veined with 
black, having the base and the middle of the outer row of white 
spots in the posterior margin of the wing yellowish. 
139. PiERis ScYLLARA, (n. s.) P. alis integerrimis albis limbo 
exteriori utrinque nigro ; anticis elongato-trigonis maculis api- 
calibus quatuor albis. 
Obs. This species comes very near to P. Lyncida of Godart. 
Its wings are white above. The upper ones have their costa 
blackish, and a triangular border at their extremity rather dentated 
on the inside. On this black border is a transverse row of four or 
five white spots, unequal in size. The lower wings have also a 
black border with one white spot, and which is simply crenated on 
the inside. The under side of the four wings scarcely diffei’s from
