1889. | LEPIDOPTERA OF JAPAN AND COREA. 475 
Rather larger and darker in colour than most of my specimens 
from Europe. 
Yokohama (Jonas and Pryer) ; Oiwake (Pryer); Gensan (Leech) ; 
North China ; Europe. 
2. ACRONYCTA TRIDENS. 
Noctua tridens, Schiff. Wien. Verz. p- 67; Esp. Schmett. iv. 
pl. 115. figs. 5-8. 
Acronycta tridens, Treit. Schmett. v. 1. 26 ; Guen. Noct. i. 
- 43. 
: Acronycta increta, Butl. Ann. & Mag. Nat. Hist. (5) i. p. 78 
(1878) ; Ill. Typ. Lep. Het. iii. pl. xliv. fig. 3 (1879). 
Several specimens coll. Pryer, labelled 4. increta. I took examples 
at Gensan. In his Catalogue of the Lepidoptera of Japan Pryer says 
of the larva of this insect, “ very like A. ¢ridens, which also probably 
occurs here.” 
The largest example in my series from Japan measures 50 millim. 
m expanse. 
Yokohama (Pryer and Manley); Gensan (Leech); Europe. 
3. AcRonycrTa Pst.

Noctua psi, Esp. Schmett. iv. pl. 115. figs. 1-4. 
Acronycta psi, Treit. Schmett. v. 1. 30; Guen. Noct. i. p- 43. 
Four examples taken by myself at Gensan in June, and Fushiki in 
July. There were no specimens in Mr. Pryer’s collection. 
Gensan, Fushiki (Leech) ; Europe. 
4, ACRONYCTA DIGNA. 
Thalpophila digna, Butl. Trans. Ent. Soc. 1881, p. 176. 
Acronycta micnaél, Oberth. Etud. d’Ent. x. p. 18, pl. ii. fig. 13 
(1884). 
Several specimens, coll. Pryer. 
I have received this species from my native collector, who took 
three examples at Gensan in July. 
Except that the secondaries of some examples are tinged with yel- 
low, this species has no character in common with Thalpophila cythe- 
rea, the insect with which Mr. Butler compares his digna ; further 
it does not agree with the characters of the genus Thalpophila, Hiibn., 
as diagnosed by Walker (Cat. Lep. Het. ix. p- 214), especially as 
regards the antennz, which in digna are simple in both sexes. 
Ranges from 40 millim. to 52 millim. in expanse. 
Yokohama, Oiwake (Pryer); Corea, Sidemi (Jankowski). 
5. ACRONYCTA HERCULEA. 
Acronycta herculea, Feld. Reis. Nov. cix. fig. 2. 
Acronycta luteicoma, Grote, var. elongata, Oberth. Etud d’Ent. 
x. p. 20, pl. ii. fig. 3 (1884.) 
Four examples, coll. Pryer. 
Yokohama, Oiwake (Pryer); Sidemi (Jankowski).
