DESCRIPTIONS OF NEW SPECIES AND VARIETIES. 77 



chenopodii, kindly furnished me by Mr. Walsh, and named by Grote, I am enabled to 

 give the essential differences, which are : 1st. In A. Cochranii, as already stated, the 

 middle area exceeds somewhat in width either of the other two, while in H. chenopodii 

 it is but half as wide as either. 2d. In the Agrotis the space between the spots and 

 between the reuiforrn and transverse posterior is dark, relieving the spots and giving 

 them ;i light appearance, whilst in the Hadena this space is of the same color as the 

 wing, and the reniforiu spot is dark. The claviform spot in the Hadena is also quite 

 prominent, and one of its distinctive features, while in the Aijrotis it is just about ob- 

 olete. 



There are specimens that seem to be intermediate between these two, but all those 

 bred by me, both male and female, were quite constant in their markings, and their 

 intermediates will doubtless prove to be distinct species or mere varieties. 



Larva Length 1.07 inches [ =26.8 mm ]. Slightly shagreeued. General color, dingy 

 ash-gray, with lighter or darker shadings. Dorsum light, inclining to flesh color, with 

 a darker dingy line along its middle. The sides, particularly along the sub-dorsal line 

 are of a darker shade. On each segment there are eight small, black, shiny, slightly 

 elevated points, having the appearance of black sealing-wax, from each of which 

 originates a small black bristle. The stigmata are of the same black color, and one of 

 the black spots is placed quite close to them anteriorly. Head shiny and of the same 

 dingy color as the body, with two darker marks, thick and almost joining at the upper 

 surface, becoming thinner below r and diverging toward the palpi. The upper surface 

 of first segment is also shiny like the head. Ventral region of the same dingy color, 

 but lighter, having a greenish tinge anteriorly and inclining to yellow under the anal 

 segment. Legs of same color. It has a few short bristles on the anterior and posterior 

 segments. 



Chrysalis. Length 0.70 of an inch [=17.5 mra ]. Light yellowish brown with a 

 dusky line along top of abdomen. Joints, especially of the three segments immedi- 

 ately behind the wing-sheaths, dark brown. The brown part of these three segments, 

 minutely punctured on the back. Eyes dark brown, and just above them, a smaller 

 brownish spot. Two quite minute bristles at extremity. 



Described from numerous bred specimens. [First Rept., pp. 75-76. Fig. 2b'. 



There is little question but that this is the ruoth briefly characterized 

 by Harris (Ins. Iiij. to Veg., p. 444) as Agrotis messoria, an examination 

 of the types confirming this view. A. repentis G. & R. and A. lycarum 

 are also conceded by Grote to be synonyms. 



PLUSIA BRASSIC/E, 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. Tapers 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 longitu- 

 dinal lines. Desci'ibed from numerous specimens. 



Chrysalis Of the normal Plusia-form, and varying from yellowish-green to brown. 



Moth 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 undula- 

 tions of the subtermiual 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
