angulosis, sub-terminalique nigro intus limhata, macula orhlcularis tcstacea, 
punctiformis ; reniformi alba : posticce cinerece, fimbria jyallida, siibfus 
macula interna diffusa. 
Size o^ Agrolis exclamationis. Superior wings blackish-grey, with the two lines 
(extra-basal and elbowed) composed each of two distant black threads, forming 
very evident elbows and angles, especially between the cellule and the sub-median ; 
the subterminal line is scarcely sinuated, shaded on the inner side with black, which 
colom- extends more or less according to the individual, from which emanate small 
nei*vural dashes of a still deeper black ; the orbicular stigma is very small, either 
concolorous or of a nut-brown ; the reniform stigma is soiled with black below, nut- 
brown above, edged exteriorily by a white line : inferior wings blackish, with the 
fringe shining and almost white, save at the internal angle ; their under-side dusted 
with black and with a cellular dash ; the large spot at the internal angle much 
diffused. Thorax obscure, grey, with the first half of the collar darker, and the 
patagia uniform. 
The ? is darker, almost black, so that all the lines and shades are nearly 
absorbed. 
I think this species is the comma of Mr. "Walker ; but, as that name 
cannot be retained, it being already employed for a European Leucania, 
I have modified it in the least possible manner. Mr. AValker knew the 
female only.

Statura N. bicommce, sed paulo minor. Al(e anticcB cinerece, nigro-

Thorax cinereus ; collari apicibusque humerorum nigris. 
This is closely related to licomma, but smaller ; of a paler grey, especially on 
the terminal space, which is very distinct, because the ground colour is not clouded 
there, whereas it has a black appearance everywhere else ; but the costa, the space 
between the ordinary lines, and the principal nervures, remain grey ; the white 
thread of the reniform stigma is often prolonged on to the nervure which follows 
it, which does not occur in bicomma : the inferior wings are paler, almost white, 
and beneath the spot at the internal angle is very distinct. The colours of the 
thorax are more marked, and the patagia are especially shorter, more notched ex- 
teriorily, and marked with a black spot at the extremity. 
The female is altogether similar to the male, or if anything paler rather than 
dai-ker.
