Here is recorded the first discovery of the moth of the genus Elwesia HAMPSON from the region other than the Sikhim district. The specimens collected in Japan (1♂1♀, Mt. Zozu, Shikoku, Nov. 14, 1964, H. TOSHIMA leg.) fairly match the description of the Himalayan, and were determind safely as Elwesia diplostagma HAMPSON, a female type of which has been known. The genitalia as figured are characteristic in having spatulate uncus, very narrow valva bearing well-developed lunar-shaped cucullus with marginal corona, and truncate bottom of saccus.

Under laboratory condition, the larvae of the Soshigaya and Nakaizu races of the Gypsy moth, Lymantria dispar L., were reared separately on leaves of rose and persimon. Females of the Soshigaya race moulted six or five times in their larval stage and males moulted five times. Females of the Nakaizu race moulted six or five times and males moulted five or four times. The relations of log-width of exuviae of head capsule to instar number were found to be presented by the curvilinear equations shown in Table 2. As shown in Fig.1, the width of head capsule of the Soshigaya race is larger than that of the Nakaizu race, and that of females is larger than that of males, and also that of individuals moulted six times is larger than that of individuals moulted five times. As shown in Table 3, the similar relations were found in the duration of larval stage, but on the contrary the pupal period of female is shorter than that of male in both Soshigaya and Nakaizu races. As is seen in Fig.2, we shall be able to determine the instar in which a larva belongs by measuring of width of exuviae of head capsule in the larvae ranging from the 1st to 3rd instars but we shall fail to tell the instar number by this method in the larvae ranging from the 4th to the last instars. The width of the head capsule, However, will fulfil the purpose of the rough presumption of instar to which a larva belongs.

Hitherto, Deudorix kuyaniana MATSUMURA has been treated as the endemic species in Formosa, but in this time, a male specimen of this species was found from Cholon in South Vietnam, and was named as the new race cholonensis, which differs from the original race in bearing some more thick darkish short bands on underside of both wings. Narathura abseus has no record in Formosa, but the late S. HIRAYAMA illustrated this species from Formosa (Musha) in his work (1939), although he has treated this species by mistake as N. birmana uchidae (=asakurae). So we must enumerate N. abseus in the list of Formosan butterflies. It seems to me very rare. Spindasis takanonis in Siga Pref. and Yamanashi Pref. represent each the new subspecies. In the former, ssp. morinis nov., black markings on underside of both wings are very much conspicuous and thick. Central two black bands on underside of forewing tend to be linked together in H shape. In the latter, ssp. ohkuranis nov., black markings on underside are generally small or slender. Of two central black bands on underside of hindwing, outer black band remarkably winds or becomes intermittent.

Five natural foodplants of Kirinia epaminondas STAUDINGER (Satyridae) are recorded. Third or fourth instar larvae were collected from Carex japonica THUNB., Carex lanceolata BOOTT., Carex dispalata BOOTT. (Cyperaceae), Poa pratensis LINN, and Imperata cylindrica (LINN.) BEAUV, var, koenigii (RETZ.) DURAND et SCHINZ. at Shinano-Oiwake (elevation 1000m) in late May and early June, 1954-1967. They pupated in late June or early July, and the adults emerged in middle or late July.

I found a hitherto unknown mature larva of Papilionidae on Sassafras randaiense (Fig.8,4m in height) at Taipinshan (1,850m), Ilan Hsien, Taiwan on the 20th of August, 1966. The larva was found sitting on the upperside of a leaf of the tree 3m above the ground. It was 60mm in length, deep green in ground colour with unique dark brown markings (Figs,1,2). It became a prepupa (Figs.3,4) on the 23rd of August and pupated on next day. The pupa (Figs 5-7) was 35 mm in length and hibernated, After 255 days of pupal stage, unexpectedly a female of Agehana maraho SHIRAKI et SONAN emerged from the pupa on the 6th of May. 1967, Judging from the circumstances, the food-plant of this butterfly seems to be Sassafras randaiense.

A larva of Agehana maraho was discovered on the upper surface of a leaf of Sassafras randaiense, which may be its food-plant, by Mr. LIAO at Taipinshan, Ilan Hsien, Taiwan. The results obtained can be summarized as follows: 1. The full-grown larva, about 60mm long, which was collected on August 20, 1966, pupated on August 24, hibernated in pupal stage, and emerged on May 6, 1967. 2. In Agehana maraho, the larva belongs to Papilio type, has some resemblance in shape and colour to that of Papllio macilentus, but can be noticed some difference in their stripes. 3. The pupa, about 35mm long, seems a kind of Papilio too. But the pupal skin with some dorso-spiracular tubercles and subdorsal tubercles, which can not be found in the other Papilionidae, feels rough.
