Ch. invenusta Kozin . (8 c) is possibly only a geographic race of agalma. The colouration is more mono¬ 
tonous, greyer without any red-brown tone. The outer transverse line is close to the reniform stigma in 
contrast to agalma. Subterminal line less distinct. Underside is much darker, only paler towards the base. 
As the name invenusta has been utilised already by Grote to refer to an american Agrotis ( Lycophotia ), I 
propose to substitute the name “kozhantschikovi”. From Minussinsk. 
Ch. honesta Stgr. (Vol. 3, p. 33, pi. 12 g). As the illustration in Main Volume is much too dark and 
unclear, we are giving a better illustration here (8 c). 
Ch. pulchrella A. B.-H. (8 c) is very close to preceding species, but it is distinctly smaller, lighter 
with brighter markings. They stand out more clearly from the grey-white ground, as do also the veins around 
the central cell and the reniform stigma. The whitish colour should also be rather more pronounced on our 
illustration. Hindwings are darker. Sajan territory. 
Ch. bonza Pglr. (Vol. 3, p. 47, pi. 12 c) (8d). This species which is compared to semna still belongs 
in this group and is in appearance very like some of the related forms. The species is smaller and with nar¬ 
rower wings than are shown on the rather poor illustration in Main Volume, the colouration besides is duller 
and more monotonous. Possibly it should be classified to Opigena next to polygona. 
Subgenus: Hermonassa Wlcr. 
H. cecilia Btlr. (Vol. 3, p. 57, pi. 13 h). 
H. arenosa Btlr. (Vol. 3, p. 57) (8 d). This species was not illustrated in Main Volume, so we are now 
giving a picture. 
H. consignata Wlcr. (Vol. 3, p. 57, pi. 13 h). — ab. ferruginea Strd. has more rusty red forewings 
without the grey-blue irroration of type. In the cell before and between the stigmata there is deeper black 
dusting. — ab. pallidipicta Strd. is a paler form. Head, thorax and basal half of forewings are pale olive 
greenish, hindwings whitish. Abdomen of same shade with reddish anal tuft. Thibet, Kashmir. 
H. incisa Moore (Vol. 11, p. 61, pi. 8 b). Of this Indian species described from Sikkim, Strand has 
described a form — kaschmiricola which is much darker than the typical yellowish form. Thorax and fore¬ 
wings inclined to dark brownish by the interspersion of black scales. Basal and costal areas olive greenish 
to beyond the centre. Hindwings brownish. From Kashmir at the boundary of the palaearctic territory. 
H. lunata Moore (Vol. 3, p. 57, pi. 13 h). According to Corti’s opinion this should not be classified 
here, but to marcida Chr. (Vol. 3, p. 34, pi. 7 e). 
H. chalybeata Moore (Vol. 3, p. 57). Of this small species of which no illustration was given in Main 
Volume, we are now giving a good illustration (8 d). 
H. clava Leech (Vol. 3, p. 57, pi. 15 k). The illustration of this Chinese species in Main Volume was 
not good and we are now giving another (8 d). The Stotzner expedition discovered this species also at the 
Omei-shan (Szechuen). 
H. pallidula Leech (Vol. 3, p. 57, pi. 15 k). The same applies to this species and we are giving a better 
illustration (8 d). Both species are probably very closely related. This species also occurs in Szechuen. 
H. finitinia Warr. (Vol. 3, p. 57). It is not improbable in my opinion that this species is identical 
with consignata-pallidipicta Strd. Description and locality of origin appear to be the same. In such a case 
Warren’s denomination would have priority. 
H. utldosa Leech (Vol. 3, p. 63, pi. 15 a). This species was placed with the Triphaena Him. in the 
Main Volume. According to Corti its position should be with the Heimonassa. It is the largest species of 
this group and we are giving another illustration (11 c). 
Subgenus: Nyssocnemis Led. 
N. obesa Ev. (Vol. 3, p. 56, pi. 13 g). This remarkable species, which does not give one the impres¬ 
sion of being an Agrotis , is being again illustrated here (8 e), as the picture in the Main Volume was not 
satisfactory. 
Subgenus: Opigena Bsd. 
0. polygona F. (Vol. 3, p. 57, pi. 13 g). The illustration is fairly good. — tutilans Sohn-Rethel (lib) 
is a much more brightly marked form from the Abruzzi. The ground colour is a warmer ochreous, the dark 
markings and shadings are lightly and faintly suffused with red, almost of the shade of Eh. bntnnea. From
