Unfor-' tunp-tely, no special attempt was made to determine, at the time, the species experimented with, but among them were Theridion tepi- dariorum, Miranda aurantia {Argiopa), Metargiope trifasciata, Marxia stellata, Aranea trifolium, Misumena vatia, and Agelena ncsvia. In no case was the bite more severe than a pin prick and though in some cases the sensation seemed to last longer, it was probably due to the fact that the mind was intent upon the experiment. Similar experiments were carried out by Blackwell (1855), who believed that in the case of insects bitten, death did not result any. 6. An American tarantula (Eurypelma hentzii). Natural size.

The question cannot be so summarily dismissed, and we shall now consider some of the groups which have been more explicitly implicated. The Tarantulas.—In popular usage, the term " tarantula " is loosely applied to any one of a number of large spiders. The famous taranttilas of southern Europe, whose bites were supposed to cause the dancing mania, were Lycosidffi, or wolf-spiders. Though various species of this group were doubtless so designated, the one which seems to have been most implicated was Lycosa tarantula (L.), (fig. 4). On the other hand, in this country, though there are many Lycosidae, the term "tarantula" has been appHed to members of the superfamily Avicularoidea (fig. 6), including the bird-spiders. Of the Old World Lycosidae there is no doubt that several species were impHcated as the s
