Chrysozephyrus ataxus is widely but locally distributed in southern parts of Japan, and is also known from Tsushima Island. The author collected the eggs of this species from that Island in the spring of 1958, and succeeded in having 10 males and 10 females of butterflies by breeding. Consequently he found the following difference between the specimens from Tsushima Island and those from other parts of Japan. Male: Upperside. Black margins of both wings are narrower, especially near the anal of the hind wing. Female: Upperside. Purple patch of the forewing is generally larger than that of subsp. kirishima-ensis OKAJIMA, but smaller than that of subsp. yakushimaensis YAZAKI. Underside; Markings are the same as those of other localities in both sexes.

A striking abnormal form of Catocala patala FELDER was illustrated here and compared with the typical one. It matches fairly well the specimen named ab. usuiensis SUGITANI (Akitu, 2: pi. 1, 1939) and is therefore the second example of this form found in Japan. On upper surface it has the median blackish band of the hindwing completely lost, remaining some amount of blackish scales on the vein 2, but on under surface this feature occurs parallelly to the forewing, in which instead of normal median band a dark speck on costa and a minute dark point at the upper angle of cell are marked. Normal in colour and in size of wings. ♂, Tokyo, 7. viii. 1958(S. SUZUKI). In the collection of the author.

Neptis ikedai SHIROZU (Figs. 1 & 3) Neallotype ♂, Puli (Horisha), Formosa, viii. 1958, In my collection, Length of forewing 32mm., Expanse 56 mm. ♂ differs from ♀ in the following points. 1) Size, smaller; the forewings shape is rather narrower and slightly produced at apex. 2) The white spot in space 2 of forewings above is more distinct, being extended into space 3. 3) The submarginal band of hindwings above is monotonous and far obscure. 4) The submarginal band of hindwings below is wider and more distinct than the above, and this characteristics of ♂ is much more clear than ♀. Strymonidia inouei SHIRO.ZU (Fig. 5) Neallotype ♂, Puli (Horisha), Formosa, viii. 1957, In my collection, Length of forewing 15 mm., Expanse 25 mm. ♂ differs from ♀ in the following respects. 1) ♂ has a brand which is rather large size, about the centre of costal margin of forewings, having faint-coloured on the upperside and even darker than the groundcolour on the underside. 2) Reddish-orange spots near tornus are reduced. Virachola rapaloides NARITOMI comb. nov. (Figs. 6 & 7) Up to now, the unique specimen has been known to science since my original description (1941), as I have been keeping another ♂ specimen in my collection, I describe it as neallotype. The difference between ♂ and ♀ is as follows. Wing shape. Producing of outer margin of hindwings at the end of vein 3 and vein 7 is equal in both ♂ and ♀, while in ♂ forewings is narrower, apex produced, and tornus makes right angle. On the other hand ♀ has broader round shape. Upperside. Groundcolour of ♀ is uniformly dark brown, and ♂ is about the same but with an exception. In ♂, the difference is a few purple patches which occupy both at whole cell and inner two thirds of space 1 in forewings, and the area between vein 2 to vein 7 in hindwings. Only ♂ hat a small dark brown brand near the base of hindwings above. Underside. Groundcolour of both sexes is greyish white, but ♂ is darker. Discocellular and median bands of both wings are broad, but narrower width in 8 , darker than groundcolour, and edged by the slender white lines. Length of forewings ♂17mm., ♀19mm.; Expanse ♂29mm., ♀33mm. Neallotype ♂, Puli (Horisha), Formosa, 30. viii. 1943, Col. F. TASHIRO ; ♀(Holotype), Noko, Formosa, viii. 1940,; In my collection. V. rapaloides is most closely resembles to Sinthusa kuyaniana (MATSUMUTA) comb, nov., but it can be distinguished from kuyaniana by the several points ; for example, remarkable difference of wing size, lacking of small black spots on the base of hindwings below, etc. Virachola ferrea ARAKI (Fig. 8) It was hitherto only one female (Holotype in ARAKI'S collection) is known to science, and it wa,s, lost during the last war, so I describe here another ♀ of this species. 1 ♀, Puli, Formosa 15. viii. 1943, Col. F. TASHIRO, In my collection.
