16. Genus: Agroperina Hmps. 
One of the most difficult genera, about which Mr. Foster H. Benjamin of Decatur most kindly supplied 
us with the most detailed informations which enable us to shed some light on this genus, and to which we 
therefore refer in the following, frequently repeating the original text. We are besides aided by reliably deter¬ 
mined specimens which were compared with the types and which were most liberally placed at our disposal 
in order to have them figured. From this genus forth, also in future typical specimens of North American species 
will be placed at our disposal, so that we shall be able to supply figures drawn from nature of this fauna being 
so little known in Europe. We therefore most gladly avail ourselves of the opportunity of expressing our greatest 
thankfulness for this assistance afforded on so large a scale by Dr. Wm. Barnes at Decatur, being the owner 
of the largest and most polytypical collection of North American species, through the kind mediation of Mr. 
Benjamin. 
The genus is very near to Parastichtis and Trachea from which it differs in the admixture of hairs among 
the hair-like scales of the thorax; the thorax exhibits in the centre a very little developed, twice keeled median 
tuft, the abdomen on the first rings small tufts, at the base hair, and laterally hair-tufts. The insects placed 
to this genus partly exhibit doubtless resemblances to the genus Protagrotis which is probably wrongly inserted 
in the Agrotids. Besides North American species also a tropical representative has been described, though it 
is doubtfully placed here. 
A. dubitans Wkr. (34 a) is a large blackish-brown species with a purple tint and some white irroration, 
with rather indistinct, somewhat grey-edged transverse lines and small maculae in greyish-white rings, the 
reniform macula with a yellowish-white lunula in the centre; the white striae of the undulate line proximally 
exhibit small black sagittae. Hindwing greyish-brown, at the margin darker. — insignata Wkr. (= sputator 
Grt.) which was considered a synonym by Hampson is somewhat redder than the type of dubitans and. in this 
respect, forms the intermediary between dubitans and cogitata. Smith even takes it to be a synonym of cogitata 
which, however, most probably is merely a form of dubitans. Canada to New York, Pennsylvania, and Ohio. 
A. cogitata Wkr. (34 a) has the red-brown colour of the wings not irrorated with blackish-brown as 
dubitans which it otherwise resembles very much; between the maculae there is a somewhat more distinct 
median shadow; hindwing somewhat lighter and with reddish fringes. Canada to California. 
A. lateritia Hujn. (34 a). This well-known palearctic species which was already described in Vol. Ill, 
p. 166, and figured there on plate 39 i, occurs in America from Canada to Colorado in a very similar form which 
we are able to figure here. 
A. obliviosa Wkr. is so very similar to lateritia that it was treated as a synonym by Hampson. It is, 
however, a distinct species of a uniformly greyish-brown ground-colour, without any darker contrasts, with 
an indistinct coniform macula and a more dentate postmedian line which is towards the hindmargin bordered 
with white. The undulate line is extinct without dark shading. Rocky Mountains. 
A. conradi Grt. (34 a) is perhaps only a somewhat more brightly coloured redder form of the preceding, 
with better developed markings. Forewing on the whitish ground strewn with a bright reddish brown, in the 
median and marginal areas somewhat darker, in the postmedian area, however, light coloured; the dentate 
transverse lines are on the averted sides bordered with whitish, behind the distal line there are vein-dots; the 
small maculae are in whitish rings and centred with brownish, the reniform macula is proximally on the median 
somewhat produced, the whitish undulate line is proximally shaded with brown. Hindwing brownish, at the 
margin a little darker. Canada to Arizona. •— nada Strd. (= ab. 1 Hnvps.), according to Hampson, is a somewhat 
redder form, but for the present nothing certain can be told about it; perhaps it is identical with pendina (34b). 
A. citima Grt. (34 a) was considered by Hampson to be a synonym of conradi to which it is very similar, 
but it differs from it in the more distinct transverse lines and maculae and generally in a somewhat stronger 
median shadow. Discovered in Arizona and probably a subspecies of conradi. 
A. indela 8m. (= morna Hmps. nec Streck.) (34 b) and the two next species have been omitted in 
nearly all the catalogues; it looks like a yellowish conradi with reddish irroration. quite uniform, without any 
strewing, and with entirely effaced marking, as if it were washed off; it is somewhat variable, but nevertheless 
of a characteristic exterior and not to be mistaken for conradi ; the antennae are slightly stronger than in conradi. 
Wyoming, Idaho, Colorado, Montana, Washington, in July and August. 
A. lineosa Sm. (= ? palliderufa Strd. = ab. 1 Hmps.) (34 b) is easily mistaken for indela, but the 
genitals are different; the transverse markings are fine and distinct, although not contrastingly relieved; it 
also differs in the distinct median shadow and the reniform macula being darker in its lower half. Alberta, 
Manitoba in July.
