LIGYDA CINERASCENS (Budde-Lund). 



Ligia cinerascens Budde-Lund, Crust. Isop. Terrestria, 1885, p. 265. 



Locality. — Hakodate, Japan. Budde-Lund says of the type that 

 it is uncertain whether it comes from Manila or Chile, or was taken 

 in Japan, but he thinks it very likely to have come from Japan. 



About six specimens, which I hesitating!}' refer to this species, 

 were taken at Hakodate, Japan. They differ from Ligyda exotica 

 in having shorter antenna? which do not reach beyond the last tho- 

 racic segment and in the much shorter uropoda, which do not quite 

 equal half the length of the body. The body is also more thickly 

 granulated than that of L. exotica., and the color is uniformly dark
