556 Mr. J. H. Leech on Lepidoptera Heterocera 



Several examples of both sexes from Omei-shan, Ta-chien- 

 lu, Ni-tou, and Chang-yang : July and August. 



Hob. Central and Western China. 



Closely allied to S. vetulata, Schiff., from Europe. The 

 male has a trifid anal tuft. 



Scotosia corrugata. 

 Scotosia corrugata, Butl. Ann. & Mag. Nat. Hist. (5)xiii. p. 275 (1884) 



There was a nice series from Yesso in Fryer's collection. 



My native collector obtained a specimen at Hakodate and 

 one at Ningpo in June; the latter agrees in colour with 

 S. vetulata from Europe. 



Distribution. Japan ; Yesso ; Eastern China. 



Scotosia rhamnata. 



Geometra rhamnata, Schiff. Wien. Verz. 109 ; Hiibn. Geom. pi. lii. 



fig. 271. 



Philereme rhamnata, Meyrick, Trans. Ent. Soc. Lond. 1892, p. 70. 

 Scotosia rhamnata, var. japanaria, Leech. Entom., Suppl. p. 53 (May 



1891). 



There were two male specimens from Oiwake in Fryer's 

 collection. 



The Japanese form of this species differs from the 

 European type in being larger and having a pale grey- 

 brown coloration ; the transverse lines are identical in 

 number and form, but the space between the two central 

 angulated lines is not darker. On the under surface the 

 difference of colour is not so pronounced and the markings 

 are typical. 



Expanse 40 millim. 



Distribution. Europe ; Armenia ; Japan. 



Scotosia dubitata. 



Phal Geometra dubitata, Linn. Syst. Nat. i. 2, p. 866 ; Clerck, Icon. 



pi. vi. fig. 2. 



Scotosia dubitata, Guen. Phal. ii. p. 445. 

 Hydriomena dubitata, Meyrick, Trans. Ent. Soc. Lond. 1892, p. 72. 



Some specimens from Yesso in Fryer's collection. 



I have received several examples from Chang-yang and 

 the province of Kwei-chow : June. 



Distribution. Europe; Japan; Central and Western China. 



Both Japanese and Chinese examples of this species are 

 paler and less distinctly marked, agreeing more nearly with 

 var. ctnereata, Steph., than with the type. 



S. (Thriphosa) Oberthuri, Hedern., from Amurland (Horse 

 Soc. Ent. Ross. xvi. p. 248 bis), is probably a form of this 

 species.
