[Received March 4, 1885.] In Mr. G. Lewis's Catalogue of Coleoptera from the Japanese Archipelago, published in 1879, he has enumerated eleven species of Cassidina and three of Hispince; of the former, two must be considered synonyms, reducing the number of species then actually known to nine. In the present account of these groups, eighteen species of Cassidince are recorded and four of Hispince. It is not probable, Mr. Lewis thinks, that further investigation will very greatly increase the number ; a few of the species known to inhabit Siberia will probably be found in the northern parts of the islands. Compared with the European and Asiatic and with the North- American faunas, it appears to m e that Japan has the proportion of species we might expect, or more in proportion if the area alone is considered ; and if we consider the genera hitherto observed, it is evident that there is more of the Eastern and Tropical element than of the North American. Europe possesses but one genus of Cassidince, viz. Cassida, while in Japan we have the distinctly Old-World tropical genus Aspidomorpha, with Coptocyclce of Eastern type. When, however, the northern islands of Yezo and Saghalien have been as fully explored, it is probable that some species may be found to modify this view. The number of species here treated of is too small to admit of generalization to any extent; but T see no reason to modify the view I have already expressed, when reviewing the Malacodermata of the same region (Trans. Ent. Soc. 1883, p. 393). The number of species which may have been derived is perhaps larger here than in some groups; but these forms are usually sufficiently different from their representatives in distant localities to show that long-continued isolation has resulted in some permanent modification of the species, and a few species appear to be really endemic.
