above alluded to,) which streak is crossed by two slender pale 
lines, these lines not parallel with each other. This last mark 
with the two pale lines across it, will alone distinguish this from 
all our other moths. 
Our next most common species is the Devastating Dart 
Jlgrotis devastator , (Plate 3, fig. 2,) thus named by Mr. Brace in 
the year 1819, in a short article upon the cut-worm, published 
in the first volume of Silliman’s Journal, page 157. And it ap¬ 
pears to be this same species, which has recently been figured 
and named Jlgrotis Marshallana by Mr. Westwood, from a single 
specimen found in England by T. Marshall, Esq., (Humphrey’s 
British Moths, vol. i, p. 122.) In this species the wings when 
spread are from an inch and a half to over an inch and three- 
fourths across. The fore wings are grayish brown, and are 
crossed by four equidistant wavy whitish lines, which are edged 
more or less with blackish. But commonly only the last one or 
two of these lines can be perceived; and the last line has a row 
of blackish triangular spots, like arrow heads, along its anterior 
side, tljeir points directed towards the base of the wing. Often 
these spots are so obliterated that only one or two of the middle 
ones can be discerned in a particular reflection of the light. 
But it is by these spots more than any other character that I dis¬ 
criminate specimens of this species; for it is variable, with its 
marks obscure and more or less obliterated, from its wings when 
flying having been fluttered and rubbed against grass, leaves, &c., 
as is apt to be the case with most of the insects of this order. 
A third species, also very common, (Plate 3, fig. 6,) differs 
generically from the two preceding, and appears to coincide more 
closely with Graphiphora than with any other genus characterised 
by European writers. It is named the clandestine owlet-moth, 
Jfoctua dandestina , by Dr. Harris. It is of an obscure brown or 
gray color, its wings when most perfect marked as represented 
in the figure. Our illustrations of these three species are quite 
exact, and will give the reader a much clearer view of the com¬ 
plicated markings of their wings than he can obtain from any 
written description.
