The author has studied Sineugraphe exusta BUTLER and two related species : disgnosta BOURSIN and longipennis EOURSIN based on many specimens. In addition to giving specific differences in general appearance and male genitalia, he has illustrated the feature of female genitalia of these 3 species as a means of specific discrimination. The local distribution of these moths are as follows : S. exusta : Hokkaido, Honsyu, Kyusyu.; S. disgnosta : Hokkaido, Honsyu, Sikoku, Kyusyu ; S. longipennis : Honsyu, Sikoku, Kyusyu. A new form of disgnosta has been also described by the author. Sineugraphe disgnosta BOURSIN f. boursini OGATA This is fairly separable from the typical form by fore wing with two black spots in cell : one of them being triangular, direct proximally to the orbicular, the other triangular or square between the reniform and the orbicular. Holotype: 1♂, Sugadaira, Nagano Pref., 4 Aug. 1951 (M. OGATA). Allotype: 1♀, Karuizawa, Nagano Pref., 30 July 1954 (M. OGATA). Paratypes: 1♂, Daisen, Tottori Pref., 16 July 1946 (M. OGATA); 1♀, Antaroma, Ishikari, Hokkaido, 25 July 1952 (T. SHIROZU) ; 1 S, 1.9, Hieizan, Kyoto, 30 Aug. 1952 (Y. HATA) : 1♂, Chyogatake, Nagano Pref., 2 Aug. 1953 (K. ISHIZUKA); 1♂, Tasirodake, Akita Pref., 7 Aug 1953 (T. SHIRAI); 1♂, 2♀, Karzuizawa, Nagano Pref., 30 July (1♀), 31 July (1♀), 2 Aug. (1♂) 1954 (M. OGATA).

The object of this paper was to clarify the confusion that has existed for many years in the nomenclature and taxonomy of moths of the Genus Adoxophyes in Japan. The genera involved privatana, congruana, fasdculana and fasciata, and of these the first is known to the important pest of green-tea, and the second is known to the important pest of apple. But, result of revision, this four species does not seen necessary to separate generically. I believe I can now correctly identify this four species as a synonym of orana (F.R.).

The young stages of Melitaea diamina protomedia MENETRIES are similar to the other species' of the same genus, as the following: Eggs are upright and slightly tapering in shape, with a small depression on the blunt top and a flat base. There are about eighteen longitudinal keels, not reaching half-way up the side ; the spaces between the keels are smooth. Down the side, they are covered with a very coarse, slightly raised network. At first they are yellowish-white tinged with green, but as the caterpillar matures within, they become brownish-yellow. They are laid all in a batch, of 40-200, on the underside of the leaves of Patrima scabiosaefolia, in July. The caterpillars hatch out about 12〜14 days after the eggs are laid, and eat up their own eggshells from which they came a moment ago except the flat bases. Soon they form colonies corresponding to the number of eggs that hatch in any one batch, and then proceed to prepare a dwelling-place con-jointly by drawing together with silk two or three leaves of the food-plant, on which they feed until the supply is exhausted. They then immigrate in company to fresh leaves and construct a larger retreat, the better to accommodate their growing bodies. At the fifth instar, towards the mid-August, and while still quite small, they spin a silken home, hibernaculum, with two or three leaves, in which they go into hibernation on the silken carpet for the winter. The caterpillar in its first instar is brownish-yellow with light brown head, while as it repeats moulting its body with glossy black head gradually becomes dark, except its light brown underside.
