of the Genera of the Aranee. 57 
Atypus, Latreille, 1804, Nouv. Dict. Hist. Nat. xxiv. p. 133. 
Only one species is included originally, A. subterranea, 
Roemer, Gen. Ins. tab. xxx. fig. 2, which Latreille identified 
by mistake as belonging to this genus. 
Type, Atypus Sultzeri, Latreille, 1804. 
Erropon, Latreille, 1804, Nouv. Dict. xxiv. p. 134. 
The only species mentioned originally has no name assigned 
to it:—“ Araignée inédite de la Nouvelle-Holl.” 
In 1806 Latreille, Gen. Crust. Ins. p. 85, quotes Missu- 
lena, Wlk., as a synonym of Eriodon, and gives a single 
species—‘‘ Species i. occatorius.’ In 1810 he definitely 
selects Misulena occatoria, Walck., as the type of the genus. 
Type, Eriodon occatorium (Walckenaer), 1805. 
Dyspera, Latreille, 1804, Nouv. Dict. p. 134, col. 1, line 11. 
Three species are quoted originally under this genus, re- 
ferred to by Latreille as “ Les Claustraliformes”’ of Walck- 
enaer, who further quotes the species Aranea punctoria, 
Villers. 
The three species are: —1. A. erythryna, Walck. ; 
2. A. Hombergu, Scop. Ent. Carn. p. 403; 3. A. pune- 
toria, Villers. 
On page 47 of the ‘Tableau’ Walckenaer limits Dysdera 
to one species, D. erythryna, Walck., which was also defi- 
nitely selected by Latreille as the type in 1810. 
Further, also, A. punctoria, Villers, Caroli Linnei Ento- 
mologia, t. iv. p. 128, pl. xi. fig. 9, is a Chiracanthium, as 
Simon states in his Ar. Fr. tom. iv. p. 247, and was removed 
to that genus by implication in 1837 by C. L. Koch. A. Hom- 
bergit, Scop., was referred to the genus arpactes by Temple- 
ton in 1834. 
ype, Dysdera erythryna (Walck.), 1802. 
SEGESTRIA, Latreille, 1804, Nouv. Dict. xxiv. p. 134, col. 1, 
line 16. 
The spiders which Latreille refers to this genus are those 
mentioned by Walckenaer, Faun. Par. 1802, p. 222, under 
“Les Tubiformes.” 
(1) Aranea senoculata, Fabr., (2) A. perfida, Walck. 
(florentina, Rossi, Fauna Etrusca, pl. xix. fig. 3). 
The same two species are mentioned under Segestria by 
Walck. Tableau, 1805, p. 48, and A. florentina, Rossi, was
