118 THE PROCEEDINGS OF THE LINNEAN SOCIETY 



live to a very great extent on some of the hardest of the 

 Weevil Beetles, and the venom is probably an acid which enables 

 the spider to divide the hard epidermis. Prefessor Thorell 

 mentions this species as from New Holland. Dr. Koch examined 

 specimens from Rockhampton, Bowen, and Port Denison. 



I have often had my attention drawn to cases of poisoning 

 from the bite of this spider, and believe that it is really venomous. 

 A correspondent, whom I have every reason to trust, wrote me 

 some time back that he had been bitten by one of these spiders 

 (a specimen of which he forwarded), and said that the poison 

 caused him three days and nights most intense pain, his arm and 

 hand slightly swollen, and the flesh around the bite a little 

 discoloured ; the muscles of the arm and the joints of the fingers 

 were stiff and painful to the touch. 



In respect of its venomous character this spider is like its 

 Corsican congener, L. malmignattus, which is reputed to be 

 venomous (though M. Walcknaer throws some doubt on this), 

 and also with American species, L. formidabilis, L. perfidus, L. 

 variolas, reported as venomous by Mr. Abbot.
