the reniform macula; a black basal ray is continued into the narrow coniform macula; the undulate line is com¬ 
posed of whitish and black sagittae. Hindwing rather light. — f. dentilinea 8m. is presumably only the $ of it. dentilinen. 
Canada and United States from Massachusetts and New York to California. 
F. aeneipennis Grt. (9 a) is a much lighter, more reddish-brownish species, similarly marked as the prece- aeneipeti¬ 
ding, but without the dark streaks behind the reniform macula and without any sagittae in the marginal area. 
Hind wing yellowish-white, at the margin and on the veins brownish. Reported from Washington and Cali¬ 
fornia. 
F. obliqua Sm. on the whole resembles Vancouver ensis in the marking, whilst in the ground-colouring obliqua. 
it varies between yellowish-brown and blackish-brown, with a ferruginous brown head and light grey meso- 
thorax; costal-marginal area somewhat darker; transverse lines double, blackish, the posterior line finely dentate, 
die line distal to it only composed of dots on the veins or also entirely absent; maculae of the ground-colour, 
finely encircled with black, ring-macula oblong, in the black ground of the cell behind the reniform macula 
a black streak to the postmedian. Hindwing brownish-grey. Described from Canada. 
F. annexa Tr. (= anteposita Gn., decernens Wkr.) (9 a) is a most common species; reddish-brown, anneza. 
below the base of the cell and subapically dusted darker with strongly dentate transverse lines, the anterior 
ones being double, the posterior one single and less distinct, with small maculae surrounded by black, the ring- 
macula obliquely elliptical, above open, behind it a black streak to the reniform macula; the coniform macula 
is long and narrow; at the undulate line light and dark sagittae, behind them dark streaks on the veins. The 
$ is entirely suffused with dark, only in the costal part and in the marginal area lighter. Widely distributed 
in the United States through Central America to Chile and Argentina. —- Larva brownish, on the dorsum with 
darker spots, light subdorsal and lateral stripes. It lives polyphagous on low plants. 
F. malefida Gn. (= inspinosa Gn., consueta Wkr.) (9 a, b) is larger, lighter with a decidedly darker malefida. 
costal area and dark collar, very similarly marked, but with a very long ring-macula which almost touches 
the reniform macula, without the black streak between them; the $ is darker grey. Just as common and of the 
same range as the preceding. — Larva likewise very similar, the brown lateral area is above bordered with white. 
Likewise polyphagous. 
F. pexa Berg. (= ingoufii Mob.) (9 a) is a large greyish-brown species with a black basal spot and a pexci. 
bent white stripe therein; behind the coniform macula a white stripe on the submedian fold; maculae small, 
whitish or brownish, pupilled with grey in a deep black cell, and also behind the reniform macula there is a 
black spot; no transverse lines; undulate line marked by white dots and black sagittae before them. Hindwing 
whitish, at the margin brownish. Patagonia. 
F. canities Hmps. (Grt.) (9 b) is lighter than annexa (9 a) with a much shorter coniform macula, canities. 
without the black cellular streak between the two upper maculae of which the ring-macula is round; the posterior 
tranverse line is very distinctly dentate, on the veins very pointedly extended; undulate line marked by small 
whitish sagittae. Hindwing diaphanous white. Argentina. 
F. experta Wkr. (= innotabilis Wkr.) (9b) has a more uniform dark brown colour; from the lower experta. 
cell-angle a distinct median line runs to the proximal margin; otherwise marked like the preceding; hind wing 
transparent white, in the $ at the margin brownish. Peru. 
F. clerica Btlr. (= carbonifera Mab.) (9 c) has, like the following, only ciliated antennae and is a clerica. 
large, almost uni-coloured purple blackish-brown insect with a contrastingly ochreous-brown or grey scaled 
disc of the thorax; on the dark ground of the wings the markings are not very prominent, only at the proximal 
transverse line and in the reniform macula there are sometimes ochreous-yellow scales. Hindwing transparent 
white, at the costal and distal margins brownish, in the $ much more extensively brownish. — f. purpurascems purpuras- 
Strd. has the head, thorax and forewing coloured more purple reddish-brown. —• In f. pusita-arenae Stgr. the ccn 
head, thorax and forewing are more ochreous yellowish-brown, strewn and dusted with blackish, with correspon- 
dingly more conspicuous markings. Chile, Patagonia, Fuegia, and Falklands Islands. 
F. agroica Dogn. approximates the preceding and is dark brown on the head and thorax, grey on the agroica. 
abdomen. Forewing brown with a slight lilac reflection, very indistinct transverse lines, the beginning of which 
at the costal margin is marked by small lighter spots, and rather large maculae of the ground-colour, finely 
surrounded by black; the reniform macula crosses the cell-end downward. Hindwing dirt\ white, at the margin 
and veins grey. Expanse of wings: 33 to 38 mm. Costa Rica (Irazu). 
13. Genus: Agrotis 0. 
It comprises the group of species with a smooth convex frons without a projection, with a broad triangu¬ 
lar shape of the wings, the abdomen being often somewhat flattened, the anterior tibiae on both sides strongly 
spined, loose hair-tufts on the prothorax which is besides intermixed with hair, like the head, and covered with 
scales.
