J r Goniloba guttata, Men. Cat. Mus. Petr. i. t. v. fig. 4 (1855). Common all over Japan and Corea; it can be easily distinguished trom P. pellucida by its longer, narrower wings, and by the spots of the hind wing, which are almost in a straight line, while in I. pellucida the arrangement is most irregular. 141. PAMPHILA JANSONIS. Pamphila jansonis, Butl. Cist. Ent. ii. p. 284. I took a single specimen at Gensan in June of what I consider the male of the type in the National collection, which is a Japanese specimen. It is very closely allied to P. pellucida, the only difference of any importance being a conspicuous pale spot near the base of the hind wing on the underside. I have a large series of P. pellucida and P. guttata, but can find no trace of this spot in any of them. 142. PAMPHILA PELLUCIDA. P. pellucida, Murray, Ent. Mon. Mag. xi. p. 172 (1875). This species is common all over Japan, Corea, and the Kurile Islands during the warm months. 143. HESPERIA SYLVANUS, Esp. Pamphila herculea, Butl. Ann. & Mag. Nat. Hist. ser. 5, vol. vii. p. 140. Pamphila venata, S, Brem. & Grey, Schmett. nordl. China's, p. 11 ; Men. Cat. Mus. Petr. i. t. v. fig. 8. Pamphila florin da, Butl. Cist. Ent. ii. p. 285 (1878). Occurs in Central Japan and Yesso, and is common at Fusan and Gensan, Corea, in June and July ; a very variable species. 144. HESPERIA SUBHYALINA. Pamphila subhyalina, <j?, Brem. & Grey, Schmett. nordl. China's, p. 10 ; Men. Cat. Mus. Petr. i. t. v. fig. 7. Allied to sylvanus, but easily distinguished by its larger size and the semitransparent patches on tbe fore wings of both sexes. Common in Corea; occurs also in Yesso, and I believe in Central Japan. 145. HESPERIA SYLVATICA. Pamphila sylvatica, Brem. Lep. Ost-Sib. p. 34, t. iii. fig. 10. Pamphila leonina, Butl. Cist. Ent. ii. p. 286 (1878). I took this species in Gensan in July, and Hakodate in August; it is recorded from Tokio. PROC. ZOOL. Soc-1887, No. XXIX. 29 |
