88 CERASTIS; ORTHOSIA. By Dr. Corti and Dr. M. Drattdt. 
but these are only visible in freshly killed specimens and they soon fade away. Dannehl described same 
rectangu- from Silesia, Petersen records them from Esthonia. — ab. rectangularis Stephan denominates an aberration 
lar>s - in which the posterior transverse band is angulated forming a right angle below the costa. Otherwise the 
specimen is very pale, orbicular stigma very large, antemedian line indistinct. From the Ctlatzer mountains. 
fumea. — fiiniea /. n. (10 e) is an interesting race from the Hi territory. It is relatively small and with narrow Avings, 
ashy grey with sooty dusky brown basal and marginal areas. In the latter the veins are pale and there 
are blackish sagittate marks before the subterminal line. Also hindwings are much paler. Type in the collec- 
tibetica. tion of Draitdt. - tibetica /. n. (10 e) denominates a very outstanding subspecies, that is A T ery large and 
with wide wings that are a monotonous smoky grey with quite extinct transverse markings and only the 
3 large pale stigmata stand out distinctly in the dusky disc. Further there are 3 heavily black sagittate marks 
in the upper half of subterminal. Hindwings very uniformly grey-brown with white fringes. Thibet. Type in 
the collection of Corti.

leucogra- C. leucographa Schiff. (Vol. 3, p. 60, pi. 14 b). The old illustration was scarcely recognisable and A\-e 
ptui. are illustrating afresh this widely distributed species (12 1). I have for instance specimens from Sutshanski- 
Rudnik. 
C. pallescens Btlr. (Vol. 3, p. 60, pi. 14 b). The illustration is good. 
caelebs. C. caelebs Stgr. (Vol. 3, p. 60, pi. 14 b). The illustration is unrecognisable and \\ r e are giving a better 
one here (12 1). 
norwegica. G. rubricosa F. (Vol. 3, p. 60, pi. 14 b). — oorwegica Strd. denotes small (wing expanse: 32 mm) spe¬ 
cimens of grey-black ground colour without red admixture and with very distinct orbicular stigma. From 
northern Norway. 
C. coryphaea Pglr. (Vol. 3, p. 61, pi. 14 c). 
sobrina. C. sobrina Bsd. (Vol. 3, p. 61, pi. 14 c). In regard to this species, Corti has declared that same is 
not a Cerastis , but should preferably be classified with the subsequent Genus Lycophotia Hb. As Ave have 
placed same in the collective Genus Rhyacia, we are temporarily leaAdng same in the present position. - 
confina. confina Kozh. differs from typical sobrina by having the transverse lines and stigmata finely and very distinctly 
indicated by black lines; otherwise they are usually indistinct. From the Tajga in the district of Minussinsk. 
Perhaps this is a separate species. 
witzenman- C. witzennianni Stndfs. (Vol. 3, p. 150, pi. 36 i). As a large number of specimens of this species have 
ni - spurs on hind tibiae, same should be placed here according to Corti and not with the Spudaea as was done 
in the Main Volume and with which it seems to have no affinity. It is very variable in colouration. A 
olivina. very pale ochreous grey form with greenish hue is named — olivina Trti. Described from Blidali (Algeria). 
'plumbum. — pluuibina Trti. is ashy grey, someAvhat reddish purple at margin. — vinosa Obth. (12 1) is a dark ochreous 
riseirino' rec ^ f° rm from Algeria and the East Pyrenees. — griseivinosa Rothsch. is a completely dark grey form that 
sa . is suffused with purplish red.— nigrolimbata Obth. from Morocco has blackened fringes. This species is extra- 
nigrolim- ordinarily widely distributed: from S. E. France through Spain and over the whole of the western N. Africa.

rhaetica- O. caecimacula Schiff. (Vol. 3, p. 61, pi. 14 c). — rhaeticaria DM. is an especially large form from the 
rm - Etschtal with bands and other markings more or less extinct, so that the wings appear smoother and plainer; 
marsicaria. $$ mostly dusky, black-brown with violet tone. — marsicaria Dhl. in contrast to same, are relatively small, 
sleek, narrow winged specimens, the $<$ almost milky white with ochreous hue, the $$ somewhat more dusky 
with brownish suffused hindwings. From the Abruzzi. 
fumosa. O. senex Guen. (Vol. 3, p. 61, pi. 14 d). — ab. fumosa Banlces are melanic specimens from England 
typhoea. (Dorset). — typhoea Trti. is a somewhat similar form that is ashy grey with violet hue. markings being black 
monticola. instead of brown, hindwings narrowly dusky at margin. From around Mount Aetna, Sicily. — nionticola Dhl. 
is the race from the high mountains in the southern Abruzzi. It is small and with Avide pale blue-grev wings 
medio- with dark scales and heavy grey-black markings. - medioitalica Dhl. in contrast to same, is large and is 
italic a. very pale whitish grey with yellow hue and faint, diffuse markings and yellowish stigmata. From the roman 
Campagna, mountains of Albania and the Sabine mountains. 
O. Indiana Guen. (Vol. 3, p. 61, pi. 14 e). 
parvispina. 0. parvisphia Tshetv. (12 1) is not an Athaumasta, but more closely resembles A. cortex. It is however 
certainly an Agrotidae and has bold spurs on hind tibiae. ForeAAdngs are pale yelloAvish grey, peppered with 
black, with short interrupted black basal streak. Transverse lines are double, especially the posterior one 
is sharply dentate, interfilling somewhat paler, stigmata large Avith delicate black circumscriptions and lighter
