Thirty-five species* of Japanese and Formosan Noctuid moths belonging to Deltote and its allied genera of Acontiinae are revised together with two European and North American species. Three new species, i.e., Protodeltote inexpectata, Sugia rufa and Neustrotia rectilineata are described. Inferred intrageneric phylogeneitc relationshps are discussed for most genera.

The cicadas belonging to the genus Cryptotympana Stål are revised. Fifty species are recognized, including 18 new species. They can be classified into 11 species-groups on the basis of the morphological characters of the ♂ genitalia. Detailed descriptions of respective species are given, together with some discussion on their distribution and infraspecific problems.

In this part, 27 species under 5 groups are described and illustrated; 9 new species, brevicorpus (from Nias), brunnea (from Simeulue) praeclara (from Borneo), ochromelas (from Flores and Solor), alorensis (from Alor), wetarensis (from Wetar), nitidula (from Vietnam), gracilis (from Thailand) and moultoni (from Sumatra) are included.

Isosturmia is revised: five nominal species are recognized and I. pilosa sp. nov. is described and illustrated from Japan. A key to 6 species is provided. Isosturmia chatterjeeana Baranov is newly synonymized with I. picta Baranov. Leiosiopsis aristalis Townsend is newly synonymized with Isosturmia inversa Townsend not with I. intermedia, and Epixorista episcopa Townsend and E. ocellaris Townsend newly with I. intermedia.

Sixteen fossil teeth of the lamnid shark, Carcharodon angustidens, from Kitakyushu are described here. These teeth are from a bed of the Ashiya Group which is considered to be the Late Oligocene. There is a wide range of morphological variations among these fossil teeth, which represent individual and positional differences on the jaw.

Growth of Takydromus tachydromoides was studied at Fukuoka in southwestern Japan. From the data of growth in SVL, the lizards were classified into three age classes. The growth rate of SVL did not differ between sexes. The mean body weight of adult lizards differed significantly between sexes, but SVL did not.
