So that they are never likely to increase quite as badly as the butter- 

 flies just now described. 



When full grown this worm weaves a very thin loose white 

 cocoon, sometimes between the leaves of the plant on which it fed, 

 but more often in some more sheltered situation'; and changes to 

 a chrysalis (Fig. 81, b) which varies from pale yellowish-green to 

 brown, and has a considerable protruberance at the end of the wing 

 and leg cases, caused by the long proboscis of the enclosed moth 

 being bent back at that point. This chrysalis is soft, the skin being 

 very thin, and it is furnished at the extremity with an obtuse 

 roughened projection which emits two converging points, and several 

 short curled bristles, by the aid of which it is enabled to cling to its 

 cocoon. 



The moth is of a dark smoky-gray inclining to brown, variegated 

 With light grayish-brown, and marked in the middle of each front wing 

 with a small oval spot and a somewhat U-shaped silvery white mark^ 

 as in the figure. The male (Fig. 81, c) is easily distinguished from 

 the female by a large tuft of golden hairs covering a few black ones, 

 which springs from each side of his abdomen towards the tip. 



The suggestions given for destroying the larvae of the Cabbage 

 Butterflies, apply equally well to those of this Cabbage Plusia, and 

 drenchings with a cresylic wash will be found even more effectual, 

 as the worms drop to the ground with the slightest jar. 



Plusia bhassicjE, N. Sp. — Larva — Pale yellowish translucent green, the dorsum made lighter and 

 less translucent by longitudinal opaque lines of a whitish-green ; these consist each side, of a rather 

 dark vesicular dorsal line, and of two very fine light lines, with an intermediate broad one. Taper* 

 gradually from segments 1-10, descending abruptly from 11 to extremity. Piliferous spots white, 

 giving rise to hairs, sometimes black, sometimes light colored ; and laterally a few scattering 

 white specks in addition to these spots. A rather indistinct narrow, pale stigmatal line, with a 

 darker shade above it. Head and legs translucent yellowish-green, the head having five minute 

 black eyelets each side, which are not readily noticed with the naked eye. Some specimens are 

 of a beautiful emerald-green, and lack entirely the pale longitudinal lines. Described from 

 numerous specimens. 



Crysalis—Oi the normal Plusia-iorm, and varying from yellowish-green to brown. 



ifloth — Front wings dark gray inclining to brown, the basal half line, transverse anterior, 

 transverse posterior, and subterminal lines pale yellow inclining to fulvous, irregularly undulate, 

 and relieved more or less by deep brown margins ; the undulations of the subterminal line more 

 acuminate than in the others, and forming some dark sagittate points ; the basal half-line, the 

 transverse anterior near costa, and the transverse posterior its whole length, being sometimes 

 obscurely double : four distinct equidistant costal spots on the terminal half of wing, the third 

 from apex formed by the termination of the transverse posterior; posterior border undulate with 

 a dark brown line which is sometimes marked with pale crescents ; a series of similar crescents 

 (often mere dots) just inside the terminal space; the small sub-cellulary silver spot oval, some- 

 times uniformly silvery-white but more often with a fulvous centre, sometimes free from, but 

 more oftpn attached to the larger one which has the shape of a constricted U, very generally 

 with a fulvous mark inside, which extends basally to the transverse anterior at costa. Fringen 

 dentate, of the color of the wing, and with a single undulating line parallel to that on the terminal 

 border. Hind wings fuliginous, inclining to yellowish towards base, and with but a slight pearly 

 lustre ; fringes very pale with a darker inner line. Under surfaces pale fuliginous with a pearly 

 lustre, the front wings with a distinct fulvous mark under the sub-cellulary spots, speckled more 

 or less with the same color around the borders of the wing, the fringes being dentate with light 

 and dark ; the hind wings speckled with fulvous on their basal half, and with the fringes as 

 above. Thorax variegated with the same color as front wings, the tufts being fulvous inclining to
