Ochlodes asahinai was described by Prof. T. SHIROZU based on a male captured in Ishigaki Island on June 4, 1962 by Dr. S. ASAHINA, and later only one male was obtained on May 30, 1963 by Mr. S. ISHIDA. M. UDAGAWA, one of the authors, obtained 1♂7♀♀of this species on May 26-31, 1968 at Mt. Omoto-dake in Ishigaki Island. The female of this species has no been known till now, so we describe it blow.

In the present paper the author dealt with the morphological characters of larvae of four species belonging to the genus Calothysanis HUBNER (Geometridae, Sterrhinae), C. amata, C. comptaria, C. dichela, and C. apicirosea. The nomenclature for the setae is coincided with that of HINTON (1946). A seta "lambda" of FRACKER (1915), commonly found in the larvae of Geometridae on A1 to A7, referred to as "seta LD", used by SIGHN (1951) in his figures. These larvae have the combination of characters. Body form strongly enlarged at posterior half of T3 and A1. Body setae extremely short, but on A1 slightly longer, especially setae L2, LD and V1. Subventral setal group on A1 unisetose, bisetose on A2 and trisetose on A3 to A5. Prolegs of mature larva bear up to 31 biordinal crotchets incompletely separated into two groups. Seta CD2 of anal proleg distinctly above level of seta L3. Seta SD1 on A1 distinctly posterior to L2. Seta D1 on anal shield slightly posterior to L3. Based on larval characters, SIGHN (1951) divided the subfamily Sterrhinae into two distinct divisions, "A" and "B". This genus belongs to "Division A" by the above-mentioned characters. Probably "Division A" may be correspond with the tribe Cosymbinii, including this genus.

A record, probably as unusual comer, of Maceda mansueta WALKER in Japan is here presented from a male specimen kept in the collecton of Entomological Laboratory, University of Osaka Prefecture, Sakai. The Specimen data as labelled are "KYUSHU/Tashiro/Kagoshima Pref./21. IV. 1958/T. YASUDA".

1. In this report, the number and relative sizes of chromosomes are described in 5 species from Bangkok. 2. It is noteworthy that the karyotype has supernumerary chromosome in Moduza procris (n,35,36) from Bangkok. 3. Mycalesis mineus (n,16,17,18) from Bangkok shows a polymorphism of the karyotype at the primary spermatocyte.

It appears now well-known that Bena fagana (FABRICIUS)(=prasinana auct.), a common Eurasian species, produces the second generation moth in different form in the warmer regions of Europe. It had been called under various names as distinct, till OBRAZTSOV (1943, 1950) published a conclusion. The oldest name applicable to the form is fiorii COSTN. (1911), of which hongarica WARREN (1913) and hispanica FERNANDEZ (1931) are synonyms. It has relatively shorter and broader forewing than in the typical or vernal form and only two median bands on it in both sexes. The moths known to us as Bena japonica (WARREN) is apparently the Japanese representation of the aestival form of fagana, occuring in major part of Japan in July towards August except in Hokkaido, where occurs only the typical form. In Japan and its neighboring areas there occurs another couple of species of the genus, named respectively kraeffti GRAESER and sylpha BUTLER. The latter form showing only two oblique median bands is, though peculiar in having purely white hindwing in both sexes, here concluded to represent the aestival form of the former appearing in early April to May. The fact was confirmed by breeding larvae obtained from ova laid by female kraeffti in spring. This species, for which the specific name sylpha BUTLER is the earlier one, is a resident of the lowlands shrubs, feeding preferably on the leaves of deciduous oak, Quercus acutissima and Q. serrata, in the area west of central Honshu. The synonymies will be given as follows. Bena fagana (FABRICIUS, 1781)=japonica WARREN, 1913, syn. nov. Bena sylpha (BUTLER, 1879)=kraeffti GRAESER, 1888, syn. nov.=magnifica LEECH, 1890, syn. nov. The difference of male genitalia between the two is slightest, but in female genitalia the shape of sclerotization of bursa copulatrix at near orifice to ductus bursae differs enough to separate them.

Geographical variations of Anthocaris cardamines LINNAEUS and Carterocephalus palaemon PALLAS in Japan were studied on the basis of many specimens from almost all of their known localities. A. cardamines distributed in the Akaishi mountain range and Mt. Yatsugatake is clearly distinguishable from A. c. isshikii, which is distributed in the Hida mountain range and Mt. Togakushi-yama. The author named ssp. hayashii to the butterflies distributed in the Akaishi mountain range and Mt. Yatsugatake. C. palaemon distributed in the Akaishi mountain range is also distinguishable from C. p. satakei distributed in the Hida mountain range. The author named the former ssp. akaishianus. In addition to these two species, some other butterflies have the geographical races in Central Japan which are similarly distributed as in the above mentioned two species. The author discussed the similality of their distribution and tried to interpret its origin.
