As a means of comparison, I give here Mr. Walsh’s translation of 
Guenee’s original description, with his own comments: 
“For the benefit of those who, like myself, do not possess a copy 
of Guenee, I subjoin his generic and specific characters of our 
insect, which have been most obligingly furnished to me by my 
friend Dr. Morris. I translate from the original French, adding, in 
brackets [ ], such further particulars as are applicable to our species : 
“Gen. Leucania , Ochs. Caterpillars cylindrical, smooth, pale, with 
fine longitudinal lines, and a sub-globular head, living on grass and 
hiding by day either in tufts [of grass], or in the interior of cut 
stems, without eating the pith of them. [Feed by night, and also 
in the forenoon.] Chrysalides ordinarily contained in cocoons 
underground. [Spin no cocoon.] Antennae [of the imagines] pretty 
short, pubescent, with two stronger ciliations’upon each joint of the 
male, sometimes serrate with whorls of ciliations. Palpi pretty 
thick, connivent, with furry hairs and with the last joint very 
short. [The two first joints embracing the front; the third de¬ 
scending decidedly.] Thorax smooth, sub-quadrate. Abdomen 
smooth, pretty long, garnished with hairs at its base above, and 
sometimes on its sides, [and also at the tip in both sexes. Legs, 
more or less hairy. Tongue, well developed. Front wings entire, 
with the tip more or less pointed, seldom having the ‘lines’ and 
‘spots’ very distinct; the latter being almost always reduced to 
a cellular point (a un point cellulaire.) In repose the wings are 
roofed at a very steep angle. 
“L. extranea, Guenee. The front wings [on the upper side] are 
very pointed at the tips, of a gray more or less reddish, sometimes 
whitish, much spe.cked with black atoms [the basal half of the 
costal margin being lighter.] The two ordinary ‘spots’ are distin¬ 
guished m the cellule by a color brighter or less tinged with red¬ 
dish. Under the ‘kidney shaped’ spot is a white point, indistinctly 
surrounded by blackish. There are no visible traces of ‘lines,’ but 
the series of black points which follows the ‘cubitus,’ is often very 
distinct. An oblique black streak [shaded off gradually towards the 
terminal margin] starts from this ‘line,’ and ascends “to the apex 
[of. the wing], and with the form of the wings principally charac¬ 
terizes this species. [All the nervures—but especially what in the 
Neuroptera is called the Median by my friend Dr. Hagen (Monogr 
Libellul, vol. 1, plate I., and vol. II., plate 22),—are more or less 
white, and more distinctly so towards their tips. Just inside the 
fringe there is a series of eight black dots, one between every two 
nervures. The white spot before referred to is always on the tri¬ 
furcation of the ‘median’ nervure and generally of an irregular 
rhomboidal form.] The hind wings are a little transparent, grey, 
with the terminal border and the nervures blackish, [the blackish 
border shading gradually into the grey. The fringe of both pairs 
of wings is pale, with a narrow dusky band inside of its middle.] 
The sexes scarcely differ. 
“The underside of the wings, which Gu«nee does not notice, is of 
an opalescent yellowish white, with the terminal margin widely 
freckled with numerous confluent dusky specks, so as to give the 
appearance of a broad, dusky band with a definite outline. The 
costal margins are also lightly freckled with similar specks. The
