The characters of this and the next group (Lycosid^), will be noticed when we come to speak of them as British spiders. At present we take in separately here one or two of them that are not British, but have acquired an ill reputation as being dangerous and venomous. They are the following, viz.:— Latrodectus Malmignatus (i%/r^).—3. Enlarged figure of do. This spider is black, with ten blood-red spots, which are more or less semilunar. It is common in some parts of the south of Europe, more particularly in Catalonia, and it possesses the dangerous power of in- flicting a poisonous wound that kills small insects instan- taneously, and affects the larger animals seriously—man himself having sometimes suc- cumbed to the stroke.
