AGROTIS. By Dr. M. Draudi'. 
A. substrigata Sm. (10 a) resembles a Feltia from the group of gladiaria, and is recognizable by the 
yellowish-white area on the proximal half in the centre of the wing, the other colouring being purple brown; 
transverse lines filled up with yellowish-white; coniform macula large, surrounded with black; the upper maculae 
dark, surrounded with brownish, the reniform macula on the median proximally produced, before and between 
them the cell is black; undulate line only definable by the brown marginal area behind it. Hindwing ochreous- 
brown with white fringes. Canada. 
A. juncta Ort. (10 b) is a small, purple greyish-brown species with black transverse lines, the maculae 
surrounded with a light colour and below flown together, and a black scpiare spot between their upper half; 
coniform macula very long, surrounded with a light colour; undulate line hardly visible; hindwing light brownish, 
towards the base lighter. Canada. — f. patefacta Sin. (10 b) is a larger, more purple black form with a dark 
hindhead which is whitish in the type. Likewise found in Canada. 
A. subporphyrea Wlcr. (10 b). Forewing purple reddish-brown, dusted with grey, with extinct darker 
transverse lines without any trace of maculae, with a light grey undulate line which is proximally somewhat 
darker. Hindwing ochreous brown. United States (Georgia). 
A. triphaenoides Dyar (= orbipuncta B. & McD.) (Ilf) has loam-coloured yellowish forewings, 
except the marginal area dusted with reddish, with a large black reniform macula, a lighter distal transverse 
line scarcely bordered with dark, and a subterminal row of dots. Hindwing blackish with lighter fringes. Arizona 
to Mexico. 
A. larga Sm. is a large, plainly marked species, similar to unicolor (10 d) greyish-brown with a reddish 
shine and a contrastingly ferruginous brown head and collar; the single transverse lines are marked by dots 
on the veins, the maculae being surrounded by disperse black scales. Hindwing greyish-brown, towards the 
base lighter. Expanse of wings: 45 to 52 mm. From Arizona in June and August. 
A. atrifrons Grt. (10 e) has grey forewings strewn with blackish, the disc and marginal area dusted 
with ferruginous brown, with black, single, finely dentate transverse lines; there is also a median shade being 
angular at the lower angle of the cell; maculae quite extinct, no undulate line; veins in the marginal area striped 
dark. Hindwing white with brownish margin and veins. Frons jet-black. From Colorado and Arizona. 
A. piscipellis Grt. (10 d) is very much like atrifrons ; ground-colour of forewing more grey, uniformly 
dusted with ferruginous brownish; no maculae nor median shade; undulate line marked by grey; frons and 
hindwing as in atrifrons. — f. aniia Dyar is a quite deep red-brown form almost only marked by the light-spotted, 
proximally darker undulate line. Arizona. -— f. exculpatrix Dyar is deep purple brown with distinctly black- 
striped veins, otherwise similarly marked, with a jet-black frons which is not black in the similar form: fortiter 
B. & McD. (10 b), and the veins are only very finely striped darker. Utah, Colorado. — f. corrodera Sin. is 
of a much brighter ferruginous brown colour, in the costal part somewhat lighter, more yellowish, the veins 
especially in the marginal area striped black; transverse lines only marked by small spots at the costal margin, 
the maculae by yellowish patches, the undulate line by small light spots between the veins. Frons not black. 
From Washington, Nevada, Colorado. 
A. cinereicollis Grt. (= pallidicollis Grt., congrua Sm.) (10 e). Forewing ochreous brownish, in the 
costal-marginal and distal-marginal parts greyer, with single, rather inconspicuous transverse lines and a small 
black basal ray; the upper maculae of a somewhat deeper tint, surrounded with ochreous, more or less confluent, 
the ground between them somewhat darker; the undulate line is only marked by the contrasting colours in 
the marginal area. Hindwing whitish, in the marginal area brownish. —- f. vocalis Grt. (10 c) has greyish-white 
forewings, in the discal area below the cell often tinted somewhat reddish-brown, the cell blackened between 
the maculae. —• f. invenusta Grt. is darker than vocalis with very indistinct markings. Both originate from 
Colorado and New Mexico. —- f. planifrons Sm. (10 c), from British Columbia, is bluish ash-grey, in the discal 
area suffused with a claret-colour, with distinct transverse lines and a faded median shade, the undulate line 
only marked by the darker tint before it. The type cinereicollis originates from California. 
A. inopinatus Sm. (10c) is very similar to the two following species. It differs from sierrae by the 
entirely closed ring-macula, a more indistinct postmedian line and the absence of the coniform macula. Hind¬ 
wing light greyish-brown. Colorado. 
A. sierrae Harv. (10 c) is on an average somewhat larger, with just as light though rather somewhat 
yellowish hindwings. Ring-macula above open, of the coniform macula there are indistinct traces and it is 
surrounded with black; reniform macula distally with a blackish spot; grey traces of the undulate line. Colorado 
and California. 
A. unimacula Morr. (= haruspica Grt., grandis Spr.) (10 b). Large, reddish greyish-brown, strewn 
with black, with single black transverse lines, the posterior line strongly dentate; maculae surrounded with 
black, ring-macula above open, reniform macula above and beneath open; undulate line light, proximally tinted 
darker. Hindwing yellowish-brown with more yellow fringes. Canada and United States, common.
