AGROTIS. By Dr. A. Corti and Dr. M. Draudt. 61 
The ground colour which has a violet-grey sheen in moerens, is here a more reddish black-brown. The 
orbicular stigma is widely triangular with open base on top and edged with delicate yellowish white scales. 
The transverse lines have not paler edges. Hind wings with more distinct darker marginal line and large 
diffuse central spot. Type one <$ from Thibet in the collection of Corti. 
Ch. melancholica Led. (Vol. 3, p. 47, pi. 12b). We are giving a better illustration (lid), as the one 
in the Main Volume is unrecognisable. 
Ch. sareptana H.-S. (Vol. 3, p. 47, pi. 12 h). 
Ch. decussa Stgr. (Vol. 3, p. 34, pi. 7 e) should certainly be placed here. According to Corti’s in¬ 
vestigations of the type, it is not a genuine Euxoa. The illustration is fairly good. The species resembles 
multangula, to which it is also closely related, but it also has a resemblance to various asiatic specimens 
of polygona. Alexander Mountains, Issyk-kid, Thibet, Minussinsk. 
Ch. versuta Pglr. (8 a). Is closely related to decussa, but has narrower wings and is not so stumpily 
built. The reniform stigma is smaller, claviform stigma scarcely indicated. Anterior to the inner transverse 
line there is a black dot in the cell. The space between the stigmata is filled with deeper black. Hind wings 
heavily dusky as in decussa. The $ antennae have only very short cilia, in decussa they are 3 times as 
long and less dense. The fore tibiae have much shorter spurs. Kuku-Nor. 
Ch. maraschi Corti ined. (8 a) is probably closest to guberlae and has similar glossy forewings, which 
however are a much paler bluish grey. The transverse lines are more continuous, the black marking between the 
stigmata varies considerably, generally it is only faint and especially towards the reniform stigma only barely 
indicated. The transverse lines commence at the costa in black dots. Hindwings duller than in guberlae. 
From the Taurus (Marash), captured in October-November. 
Ch. sordescens Stgr. (Vol. 3, p. 54, pi. 13 b). The rather poor illustration is replaced here by a better 
one (8 d). According to Corti this insignificant species and the following ones shoidd all be classified here. 
It looks somewhat like maraschi, but is not so glossy. Transverse lines much fainter, the posterior one al¬ 
most extinct. Forewings duskier towards margin. The cell between the stigmata filled with black. Hind- 
wings much darker. W. Turkestan. 
Ch. glabripennis Corti (8 a) reminds one somewhat of multifida. Forewings similarly mouse-grey with 
black basal streak. The inner line double, pale grey. Claviform stigma a black triangle. Orbicular stigma 
longish round and ojien on top diffusing into the paler costal streak. Cell below same filled with black. Reni¬ 
form stigma rather indistinct. Costa with black spots. Below the reniform stigma a black longitudinal streak. 
The outer transverse line merely indicated, double. Marginal area mouse-grey with subterminal line indicated. 
Hindwings impure white, veins and margin darker. S. Urals; Transcaspia. 
Ch. deplanata Ev. (Vol. 3, p. 48, pi. 10 h) (8 b) is fairly close to the multangula group. The illustration 
in Main Volume is much too black-grey and we are giving a better illustration of this much more brownish 
species. 
Ch. kononis Mats, does not closely resemble any other species, but is classified next to deplanata. Fore¬ 
wings dark brown, the undulate subbasal line is indistinct, double, somewhat interfilled with white in centre. 
The anterior transverse line is double, the outer part more heavily filled with white. The large oval orbi¬ 
cular stigma is pale grey, the large reniform stigma still paler, with black spots on each side. The double 
postmedian line is similarly interfilled with white. Marginal area widely pale grey, therein a white speck 
on costa. Hindwings pale grey with grey submarginal band. Wing expanse 34—36 mm. N. Saghalin (Alex- 
androvsk). 
Ch. agalma Pglr. (Vol. 3, p. 48, pi. 10 h) (8 b). In the illustration in Main Volume colours constrast far 
too much. It is a nice species with characteristic markings and we are giving a better illustration here. 
Ch. semna Pglr. (Vol. 3, p. 48). Of this beautiful species we are able to give an excellent illustra¬ 
tion (8c). Besides the locality Askhabad, the species has now also been taken in the Taurus (Marash). 
Ch. albifurca Ersch. (= reticulata Kozh.) (Vol. 3, p. 48) (8 c). As no illustration was given in the Main 
Volume, we are giving one here. It is a relatively common species of very wide distribution. 
Ch. obnubila Corti was denominated from a $ in the Pungeler collection and is classified here under 
reserve. Forewings glossy mouse-grey with black basal streak and a black outwardly concave arc above same. 
Black inner transverse line. Orbicular stigma elliptical and pointed, between same and the reniform stigma, 
the cell is black. Outer transverse line extinct. Subterminal line indicated and there are traces of sagittate 
marks in front of same. Hindwings unicoloured grey-white. Wing expanse 30 mm. Transcaspia (Arwas). 
Ch. nivisparsa Btlr. (Vol. 3, p. 46, pi. 10 e). Also this smaller species is classified near to multangula. 
The illustration in Main Volume is more or less recognisable, only the markings are shown as too diffuse.
