MDIEEASTEIA, MELANOGRAPHIA. Bv Dr. A. Seitz. 



bryophilalis. R. bryophilalis SIgr. (10 d). Similar to the preceding, only darker grey; but the dark transverse 



stripes which cross the median portion are visibly darker, especially in the costal area of the forewing, 

 and form an obtuse angle at the median. A white, comma-shaped dash is placed below the middle of 

 the costa. In Amurland and on Askold, end of June and July. 



triangulalis. R. triangulalis Lefc/i (10 d). Similar to the two preceding, also dark grey, but much larger, as large 



as gigantula and iogaiulalis. Large black raised blotches are situated at the base, in the middle of the cell 

 and in the apex of the cell of the forewing. The sUghtly curved outer discal line bounds the hghter 

 marginal portion, which is also traversed by an irregular darker yia\y line. Japan (Satsuma). 



liijrunula. R. tigranula Piingl. (10 d). Forewing clear silvery white with the usual raised blotches of scales 



near the base, before the middle of the costa, and in the apex of the cell; hindwing uniformly dark grey 

 with light fringes. Found by Korb at Kasikoparan in Eussian Armenia. 



costalis. R. costalis Stgr. (10 e). As large as the preceding, but the forewing duU instead of clear white, 



and traversed by dirty grey bands before the margin and in the centi-e. Hindwing lighter grey than in 

 iigranula and a little smaller. The patches of scales small Ijut rather high; there is generally a black spot 

 near the one at the apex of the cell. Near Chabarovsk in Amurland, at the Ussuii and on Askold, in July. 



aculidu. R. acutula Piingl. (10 e). One of the most delicate forms of the genus; forewing long, pointed and 



proportionally narrow, thinly scaled, light yellowish grey. The 3 usual patches of scales near the base, 

 at the centre and at the apex of the cell. A curved line, concave towards the base and running directly 

 onto the patch of scales situated in the middle of the cell, on which it is acutely elbowed, bounds the 

 rather darker basal area. The marginal area is limited by an outer transverse line, S-shaped and inter- 

 rupted at the median vein. Hindwing transparent light grey-brown, with very long fringes. Found by 

 RfcKBEii. near Aksu in Turkestan, in ilay. 



striguki. R- sfrjgula Schiff. (= strigulalis Hbn., lineolahs Ev.) (10 e). Considerably smaller than the preced- 



ing, but with much brighter and more vivid markings. The 3 patches of scales at the base, middle and 

 apex of the cell rather large. Before and again behind the centre of the forewing there is a slightly 

 curved dark transverse line edged with a lighter shade. In the basal and marginal areas the black veins 

 are sharply defined on the light ground. Throughout Europe with the exception of the Iberian Peninsula, 

 from Scandinavia to Italy, and from France and England to the Balkan Peninsula and Asia Minor. — 

 In specimens from Great Britain and Ireland the outer portion of the wing is darker; this is the form 

 inonachalis. monachalis Haic. — Larva more or less reddish yelloM" ochre, with broad yellow dorsal line edged with 

 brown, with light hairs, a black spot on segment 7; head dark brown with a yellow triangular spot. 

 Until the beginning of June, on young oaks. Cocoon like parchment, intermixed with fibres of bark. 

 Moth in June and July. Pungeler informs me that he considers Treitschke'.s statement that it 

 also occurs in April a mistake. Anyhow, the occurence of a second brood in Central Europe has not 

 been proved. 



3. Ueiuis: Hiiuerastria Butl. 



The name is taken from a superficial resemblance of this genus to the Noctuid genus Erastria, 

 which caused the author of the first discovered form to describe it as such. Distinguished from the 

 preceding genus liy tiie .intennae of the o, which are ciliate and not bipectinate. 4 species are known, 

 one of which occurs in North America, another very small one in Ceylon, the two others inhabiting the 

 Palearctic region. 



M. mandschuriana Oherih. (10 e). Thorax and forewing white, the median area brownish with light 

 and dark shading; a white submarginal line shaded with brown on both sides; abdomen and hindwing 

 hght brownish grey. From Suchan and Ussuri, near Chabarovsk and Yladivostock, on Askold, in Corea 

 and Japan. 



longivenlris. M. longiventris Fou]. (10 e). Size and shape of the wings as in the preceding, but more robust, 



with stouter thorax and larger head. The inner portion of the marginal area of the forewing, which is clear 

 white in mandschuriana, as well as the basal portion are shghtly clouded with brown. Near Mupin in 

 Sze-chuen; also found in Further India. 



mand- 

 schuriana. 



4. Genus: Melauog'i'apliia Hamps. 



This genus, erected b\- Hampsox for only two species, is Indian, but one of the species has also 

 been found in Fuchow and Tse-kiang. According to Hampsox it is distinguislied from Nola by the 

 branch of the subcostal which runs to the outer margin of the forewing and which IL^vmpsox calls vein 7, 

 originating beyond the subcostal vein 10 in this genus, while in Nola it branches off before the origin of 

 that vein.
