Westring, on the stridulation of males of Theridion; on the stridulation of Reduvius personatus; on the stridulation of beetles; on the stridulation of Omaloplia brunnea; on the stridulating organs of the Coleoptera; on sounds produced by Cychrus. Westropp, H.M., on reason in a bear; on the prevalence of certain forms of ornamentation.
From the extreme variability of colour in the male of some species, for instance of Theridion lineatum, it would appear that these sexual characters of the males have not as yet become well fixed.
The countryman declares this for a fact and the doctor does not always dare deny it. In the neighbourhood of Pujaud, not far from Avignon, the harvesters speak with dread of Theridion lugubre, first observed by Leon Dufour in the Catalonian mountains; according to them, her bite would lead to serious accidents.
Thecla rubi, protective colouring of. Thecophora fovea. Theognis, selection in mankind. Theridion, stridulation of males of. Theridion lineatum. Thomisus citreus, and Thomisus floricolens, difference of colour in the sexes of. Thompson, J.H., on the battles of sperm-whales.
So far from laughing, I reflect and enquire, when the Calabrian peasant talks to me of his Tarantula, the Pujaud reaper of his Theridion lugubre, the Corsican husbandman of his Malmignatte. Those Spiders might easily deserve, at least partly, their terrible reputation.
Azara has described a gregarious spider in Paraguay, which Walckanaer thinks must be a Theridion, but probably it is an Epeira, and perhaps even the same species with mine. As all the spiders which I saw were of the same size, they must have been nearly of the same age.
Azara has described a gregarious spider in Paraguay, which Walckanaer thinks must be a Theridion, but probably it is an Epeira, and perhaps even the same species with mine. I cannot, however, recollect seeing a central nest as large as a hat, in which, during autumn, when the spiders die, Azara says the eggs are deposited.
