LEPIDOPTERA. 345 



and have a small central crescent and the veins dusky. The 

 head and thorax are chinchilla-gray; the collar is edged with 

 black; and the abdomen is light brownish gray. It expands 

 one inch and four tenths. 



The smallest of these rustic moths may be called Ag-rotis 

 tessellata, the checkered rustic. It probably comes near to the 

 oceUina and oqmlina of Europe, which, however, I iiave not 

 seen. The fore wings are dark ash-colored, and exhibit only a 

 faint trace of the transverse double wavy bands; the two ordi- 

 nary 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 expands 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 agi'ees, in the main, with 

 the description given of the Phalmna Noctiia devastator, by Mr. 

 John P. Brace, in the first volume of Professor Silliman's 

 " American Journal of Science ; " and may therefore be called 

 Ag-rotis devastator. It somewhat resembles Dr. Boisduval's 

 figures of the Ag-rotis 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 transverse 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 is very com- 

 mon between the tenth of July and the middle of August. 

 Like all the foregoing species, it flies only at night. Accord- 

 ing to Mr. Brace, this moth lays its eggs in the beginning of 

 autumn, at the roots of trees, and near the ground; the eggs
