It expands one inch and four tenths. The smallest of these rustic moths may be called Agrotis tessellata (Fig. 221), the checkered rustic. It probably comes near to Fig'221 the ocellina and aquilina of Europe, which, however, I have not seen. The fore wings are dark ash-colored, and exhibit only a faint trace of the transverse double wavy bands; the two ordinary spots are large and pale, and alternate with a triangular and a square deep black spot; there is a smaller black spot near the base of the wing. The hind wings are brownish gray in the middle, and blackish behind. It ex-# pands one inch and one quarter. The fifth species I am assured by one of my friends is the moth of the cabbage cut-worm. It agrees, in the main, with the description given of the Phalcma Noctua devastator, by Mr. John P. Brace, in the first volume of Professor Silli- man's "American Journal of Science"; and may therefore be called Agrotis devastator. It somewhat resembles Dr. Boisduval's figures of the Agrotis latens of Europe. The fore wings are of a dark ashen-gray color, with a lustre like satin; they are crossed by four narrow wavy whitish bands, which are edged on each side with black; there is a trans- verse row of white dots followed by a row of black, arrow- shaped spots, between the third and fourth bands, and three white dots on the outer edge near the tip; the ordinary spots are edged with black and white, and there is a third spot, of an oval shape and blackish color, near the middle of the wing, and touching the second band. The hind wings are light brownish gray, almost of a dirty white in the middle, and dusky behind. The head and thorax are chinchilla- gray ; and the abdomen is colored like the hind wings. It expands from one inch and five eighths to one inch and three quarters. This kind of moth
