specimens." Sir George Hampson, after describing the Indian 

 form, remarks that the European form " usually has the dark 

 lines and patches of fore wings more prominent and the latter 

 tinged with rufous." 



SCOTOSIA RHAMNATA, Sclliff. 



Philereme rhamnata, Meyr. 



This species is represented in Japan by a form which Mr. 

 Leech describes as var. japanaria which "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." 



Not recorded from any other part of Eastern Asia. 



ScoTosiA DUBiTATA, Linn. 



Hydriomeua duhitata, Meyr. 

 Occurs in Japan and Central and Western China. 

 ' The specimens from China and Japan appear to be referable 

 to var. ciiiereata, Steph., as they are paler in colour than the 

 type, and the markings are not so well defined. Mr. Leech 

 considers that Scotosia (Thriphosa) oberthiiri, Hedem., from 

 Amurland, may probably be a form of S. duhitata. 



EucosMiA (Scotosia) certata, Hb. 

 Calocalpe certata, Meyr. 



This species is found in Amurland, Isle of Askold, Japan, 

 Yesso, and Central China. 



Some of the Japanese specimens are strongly marked (var. 

 varia, Hedem.). One male example from Ichang, Central China, 

 which is very like a specimen in the series of S. certata from 

 Japan in the National Collection, " has the central fascia of 

 primaries well defined, the inner edge rather deeply indented 

 towards costa, and the outer edge more than usually dentate." 



EucosMiA (Scotosia) undulata, Linn. 



Calocalpe undulata, Meyr. 

 Occurs in Amurland and Japan. The specimens are typical. 



Phibalapteryx tersata, Hb. 

 Eucymatoge tersata, Meyr. 



Eecorded from Japan and Central China. 



The Japanese specimens " more nearly approach var. tetri- 

 cata, Guen,, than the type form, but they are not quite identical 

 with either." 



Var. chinensis, Leech. — " Smaller than typical specimens and 

 rather redder in colour ; less striated with white, and the sub- 

 marginal white line is much obscured ; there is a dusky shade 

 before the second line of primaries and also one before the sub-
