of the Genera of the Aranee. 495 
Latropectus, Walckenaer, Tableau, p. 81 (1805). 
Two species only are referred to this genus originally :— 
(1) L. tredecim-guttatus, Rossi, Italy ; (2) L. mactans, Fabr. 
t. i. p. 410, America. 
In 1806 lLatreille mentions this same species under 
Walckenaer’s generic name, and in 1810 definitely selected 
it as the type of the genus. 
Thorell (Nov. 18, 1869) and Simon (Oct. 10, 1894) both 
quote this same species as the type. 
Type, Latrodectus tredecim-guttatus (Rossi), 1790. — 
Europe. 
Storena, Walckenaer, Tableau, p. 83 (1805). 
A single species was originally referred to this genus— 
Storena cyanea, Walck., Nova Gallia—which remains as 
type. 
Type, Storena cyanea, Walckenaer, 1805.—New South 
Wales. 
Uxosorvs, Latreille, Gen. Crust. Ins. i. p. 109 (1806). 
A single species was originally referred to this genus— 
U. Walckenaerius, Latr.—and was also quoted by Latreille 
as the type in 1810. 
Type, Uloborus Walckenaerius, Latreille, 1806.—Hurope. 
Cuotno, Walckenaer; published by Latreille in Gen. Crust. 
Ins. iv. p. 370 (1809). 
A single species was originally referred to this genus— 
Clotho Durandi, Walck. In selecting the type in 1810 
Latreille speaks of the species as manuscrit communiqué, so 
that he was simply editing Walckenaer’s genus and species. 
The name Clotho was, however, preoccupied by St. Fonds for 
the Mollusca in 1808, and has since been superseded by the 
name Uroctea, Dufour, 1820. 
Type, Clotho Durand:, Walckenaer, 1809.—Europe. 
Episinus, Walckenaer ; published by Latreille in Gen. Crust. 
Ins. iv. p. 371 (1809). 
A single species was originally referred to this genus— 
Episinus truncatus, Walck., Hab. in Agro Taurinensis. In 
quoting this as the type in 1810 Latreille adds “ MS. com- 
muniqués,” so that both genus and species must be referred 
to Walckenaer. 
Type, Episinus truncatus, Walckenaer, 1809.—Hurope.
