Ammophila infesta SMITH, 1873 Ammophila sabulosa infesta: TSUNEKI, 1967c, p. 10, 12, 20; 1968, p. 1 — 7. Specimens examined: 5 9 1 cf ••> Kaesong, Mts. Pakyon, Pakyon popo, 27 km NE from Kaesong, 8. IX. 1971 (No. 244). Distribution : Japan and Korea. Remarks. — Relying on the morphological characters I placed till recently the present species as a local race of A. sabulosa and thought to have confirmed that A. infesta lived allopatric with another subspecies, A. s. nipponica TSUN., namely, that infesta was the montane race and nipponica the lowland race. Later, however, through the further investigations of my colleagues and myslf over a wide range of localities it was clarified that the allopatric occurrence of both the forms was not always the case, sometimes they lived sympatric with each other, not only at the believed bordering zone of distribution, but over a considerably broad area also, although it was generally certain that the habitat segregation was the rule between them. Moreover, there is an important difference in biology. Most of the observed nipponica provision the larval cell with more than one caterpillars, while infesta as a rule with a single caterpillar. On the bases mentioned above I reallocated infesta to its original status. 4. Ammophila sabulosa nipponica TSUN., J967 Ammophila sabulosa nipponica TSUNEKI, 1967c, p. 23; 1968a, p. 1 — 7. Specimens examined: 1 çf, Prov. Kanwon, Kumgang san, Go-song chon: upper reaches of brook below Hotel, 30. V. 1970 (No. 69, leg. MAHUNKA et STEINMANN); 1 çf*, Kengia Bagyon san, San-chon tong, about 20 km SE from Kaesong, 8. VI. 1970 (No. 112 do.); 10 cf., Prov. South Pyongan, Chang-lyong san, 50kmNof Pyongyan, 13.

VIII. 1971 (No. 197); 5 9 1 cf •> Kaesong, Mts. Pakyon, Pakyon popo, 27 km NE from Kaesong, 9. IX. 1971 (No. 250): 1 9, do., 10-12. IX. 1971 (No. 257); 1 9, Mt. Pakyon, 20 km NE from Kaesong, 11. IX. 1971 (No. 260). Distribution: N. China, Mancburia, Korea and Japan (?Ussuri region and Kamchatka). Remarks. — In the Korean specimens of this species the mesonotal transverse striae in the male are on an average stronger and more distinct than in the Japanese representatives, though the variation ranges considerably overlap. In the female, however, the difference in the sculpture of the area is rather slight or almost none. This makes me hesitate to treat the Korean population as another subspecies. In the male specimen marked with an asterisk çf* in the above list the mesonotum is markedly impressed on the medio-anterior half, as if in a different species. Otherwise, however, it agrees in characteres completely with others of A. s. nipponica.
