596 CLASS ix. 



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., FRISCH Beschr. v. atterl. Ins. vm. Tab. 

 2, CLERCK Aran. Suec. PL 4, Tab. 8, fig. 2, KOCH in HERRICH-SCH^PFEB 

 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 BONNET of a contest between a spider and an ant- 

 lion, into whose hole it had fallen. Contemp. de la not., xnieme Partie, 

 chap. 42. ((Enures compl. eM. 8vo. Tom. IX. pp. 411, 412.) 



To the genus Lycosa some larger species also belong ; these are the cele- 

 brated Taraniulce (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 Apulice WAECK.) is figured, 

 amongst others, by ALBIN Spiders PL 38, HAHN Arachnid. I. Tab. 23, 

 GURIN Iconogr., Arachn. PI. i, fig. 6 ; according to WALCKENAER that 

 found by LEON DUFOUR in Spain is a different species, Ann. des Sc. tint. 

 2e SeVie in. 1835, PI- 5> &g- I > 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 (/'.) 



(The genus is allied to the next subdivision, and perhaps might 

 more correctly be placed there.)

 Ins. Tab. 4, fig. 9, WALCK. Hist. d'Aran. in. PI. 8, &c. 



F. Saltigradce 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.
