230 THE ENTOMOLOGIST. 



Aectia caia, Linn. (=ph<eosoma, Butl.). — Variable; but so 

 far none of the more striking aberrations seen in British 

 collections have been recorded from Japan. 



Spilosoma fuliginosa, Linn. 



S. menthastrt, Fabr. (= punctarium, Cram.). — "Varies 

 greatly in size and number of spots on the wings ; also in 

 colour of body, which ranges from pale yellow to vermilion. 

 Further, the ground colour of primaries and thorax is buff 

 instead of the normal white, agreeing in this respect with 

 examples from the North of England."— (Leech.) 



S. lubricipeda, Esp. — Is represented by seriatopunctata, 

 Motsch. 



HEPIALIDiE. 



Hepialus hectus, Linn. 



Cossin^;. 



Cossus ligniperda, Fabr. — Is represented in Japan by 

 C. vicarius, Walk. 



Zeuzera pyrina, Linn. (= asculi, Linn.). 

 Liparid^. 



PORTHESIA CHRYSORRHCEA, Linn. 



P. auriflua, Fabr. — The Japanese males are more spotted 

 than British examples of the same sex. 



Leucoma (= Stilpnotia) salicis, Linn. — Japanese specimens 

 are rather more densely scaled than those from Europe. 



LffiLiA ccenosa, Hiibn. (= sangcdca, Moore).— Japanese spe- 

 cimens are rather darker coloured than European examples. 



Ocneria (= Porthetria = Lymantria) dispar, Linn. (= 

 japonica, Motsch.). — Mr. Leech says: — "Except that they are 

 somewhat larger, male examples of L. japonica, Motsch., and 

 hadina, Butl., are not separable from European males of 

 L. dispar in my possession ; whilst between umbrosa, Butl., and 

 other males of L dispar from Europe, also in my collection, 

 there is not even a difference of size ; consequently I cannot 

 regard these insects as anything but forms of L. dispar." The 

 specimens from Japan range in expanse from 37-71 millim., 

 male : and from 48-114, female. 



Psilura (= Lymantria) monacha, Linn. 



Dasychira pudibunda, Linn. (= pryeri, Butl.). — Japanese 

 examples are rather different to European specimens, and are 

 referable to pryeri, Butl., with which piidica, Staud., appears to 

 be identical. 



Orgyia gonostigma, Fabr. (= approximans, Butl.). — Appears 

 to be a local species in Japan.
