137. Pontia crokera (n.s.) P. alis integerrimis niveis anticis apice punctoque nigris, posticis cinereo-submarginatis subtus flavo-irroratis. P. crokera. Captain P.P. King, manuscripts. Obs. This insect is of Godart's fifth size, and comes very near to his Pieris nina. The wings are of a fine white colour, particularly the upper. These have their summit black, and a minute black point, near the middle. The under wings are without any spots, but are bordered behind by a cinereous thread. The underside 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 fine undulating or rather incontinuous lines of a yellowish colour. The species has been named by Captain King, after John Wilson Croker, Esquire, M.P., and first secretary to the Admiralty. 138. Pieris niseia (n.s.) P. alis albis limbo late nigro; anticis macula media nigra limboque albo-trimaculato; posticis subtus nigro-venosis limbi maculis luteo-notatis. Obs. This insect comes very near to the P. teutonia of Godart and Donovan, particularly in its underside. 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 underside, but there communicates by a transverse, short, and rather curved, black band, with a black superior edging of the wing. In other respects the underside of the superior 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 underside 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 apicalibus 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 underside of the four wings scarcely differs from the upper, except that the black borders above mentioned are in general more pale, and those of the lower wings are broader than on the upper side. 140.
