These species live on the ground, and run very rapidly. The females 
carry their egg-sac with them, which is attached by a few threads to the 
abdomen. Sp. Lycosa saccata L., Friscu Beschr. v. allerl. Ins. vit. Tab.

Deutschl. Ins. Heft 120, Tab. 8. This species is the most common in the 
north of Europe. To this genus and probably to this species is to be 
referred the account by Bonner of a contest between a spider and an ant- 
lion, into whose hole it had fallen. Contemp. de la nat., xititme Partie, 
chap. 42. (Quwvres compl. éd. 8vo, Tom. 1X. pp. 411, 412.) 
To the genus Lycosa some larger species also belong ; these are the cele- 
brated Tarantule (Aranea Tarantula L.) of the south of Europe and various 
other regions of the old world. They are of different species. The true 
Tarantula of Italy and Spain (Lycosa tarantula Apulie WALCK.) is figured, 
amongst others, by ALBIN Spiders Pl. 38, Haun Arachnid. 1. Tab. 23, 
GuéRIN Iconogr., Arachn. Pl. 1, fig. 6; according to WALCKENAER that 
found by Léon Durour in Spain is a different species, Ann. des Sc. nat. 
2e Série m1, 1835, Pl. 5, fig. 1; this spider, according to his observation, 
lives in holes in the earth, of which the outlet is surrounded by a little 
raised wall that is covered on the inside with web. That the bite of this 
spider is said to be followed by a dancing madness, that can be cured by 
music, is as well known as it is incredible. 
Sphasus WALCK., Oxyopes LATR. Ocelli unequal disposed in 
four pairs, those of the first pair approximate, of the third pair most 
remote of all Ig 2) : 
(The genus is allied to the next subdivision, and perhaps might 
more correctly be placed there.)

F. Saltigrade Latr. Ocelli unequal, arranged nearly in the 
form of a square; the anterior lateral placed towards the angles of 
the anterior margin of cephalothorax, the two posterior remote from 
each other by the whole breadth of cephalothorax, or opposite to 
the former. First pair of feet with thighs mostly thick. Thorax 
large, deep, oblong. 
Erratic spiders, not forming nets, pursuing their prey by running 
and rushing upon it with a leap. 
Myrmecium Latr. Ocelli arranged in three rows ; the anterior 
of four ocelli, with two middle larger forming with the second row 
a square; the two last distant, set on tubercles. Cephalothorax 
divided by strictures, elongate. Abdomen small. Feet slender.
