of the Genera of the Aranez. 61 
De Geer, t. vii. p. 251; Clerck, pl. iii. fig. 1; Lister, t. xix. 
fig. 19. 
Both these species are congeneric, but in 1810 Latreille 
selected as the type of the genus “ Araignée renversée 
5 : Se op CaaS : : 
sauvage,” De Geer, which is identical with A. triangularis, 
Clerck. 
Type, Linyphia triangularis (Clerck), 1757. 
TETRAGNATHA, Latreille, 1804, Nouv. Dict. xxiv. p. 135, 
col. 1, line 5. 
One species only was included under Les Spiraliformes ”’ 
by Walckenaer, Faun. Par. p. 208, namely Aranea extensa, 
Fabr. p. 407. 1. 
Type, Tetragnatha extensa (Linn.), 1758. 
ARANEUS, Clerck, Svenska Spindlar, 1757, p. 22, &e. 
This genus includes sixty-seven species, which were first 
split up by Latreille in 1804, Nouv. Dict. p. 185, col. 1, 
line 8. 
Under Aranea Latreille places three species only, thus 
limiting the genus to (1) A. clavipes, Fabr., (2) A. diade- 
mata, Clerck, (3) A. spinosa, abr. 
Neither the first nor the third species, however, nor any 
species congeneric with them, was originally included in the 
genus by Clerck, and therefore A, diadematus, Clerck, alone 
ean be the type. 
Latreille had no power or right to select A. domestica, 
Fabr., as the type of the genus Araignée, Aranea, or A. dia- 
dema, Linn., the type of petra, Walck., as he does in his 
selections of 1510, having already himself, in 1804, limited 
the genus to one species only, A. diadematus, Clerck. 
Type, Araneus diadematus, Clerck, 1757. 
Hereropopa, Latreille, 1804, Nouv. Dict. xxiv. p. 135, col. 1, 
line 36, 
Under this genus are included ‘ Les Cordiformes” of 
Walckenaer, Faun. Par. tom. i. p. 227 (1802), with Aranea 
venatoria, Linn., in addition, and another species bearing no 
name. 
“ Les Cordiformes’”’ include twenty species :—Aranea ob- 
longa, argentata, rhomboica, pigra, bilineata, aureola, cespitum, 
tigrina, truncata, emarginata, rotundata, floricola, violacea, 
citrea, calycina, cristata, fucata, dauct, diana, and delicatula, 
The genus was first broken up by Walckenaer in the
