Show 1888.] LEPIDOITERA OF JAPAN AND COREA. 623 spot placed near the costa and directly above that last referred to ; one has a fourth spot towards apex. On the other hand, there are specimens with but the slightest trace of a spot at anal angle. As a rule the female is without markings, but sometimes a brownish spot appears at anal angle, and one example of this sex in Pryer's collection has the basal spot also well developed. There is considerable difference in size, as will be seen by the following measurements :- Smallest 8 24 millim. Largest 8 36 millim. „ 2 33 millim. „ $ 46 millim. Thus it will be seen that the largest $ is almost twice the size of the smallest 8 in wing expanse, whilst this last is one third less in expanse than the largest 8 • Yokohama, Oiwake, Yesso (Pryer) ; Fushiki, Gensan (Leech) ; Ningpo; Armenia, Altai, Amur, Europe. 208.

Of the type of this species, which Bremer says is very like helladia, Cram., I have no specimen, but there were two examples of var. piperita in Pryer's collection taken at Oiwake. These very closely resemble Porthesia snelleni, Staud., Rom. Mem. sur Lep. iii. p. 207, pl. xii. fig. 3. Oiwake (Pryer). 210. ARTAXA INTENSA. Artaxa intensa, Butl. Ann. & Mag. Nat. Hist.

Some of the specimens have two distinct black spots near apex of primaries, others have only one, whilst some other examples again have not a trace of any such marking. Further, there are two specimens which appear to m e to be varieties of this species ; one of these is identical with jlavinata, Walk., and the other with conspersa, Butl. Without a longer series it is not possible to form an opinion as to the legitimate rank of these two last. Yokohama (Jonas and Pryer) ; Oiwake (Pryer); Tsuruga, Fusan, Gensan, Ningpo (Leech). 211.
