Certain species, resembling Ants, elevate their anterior legs and make them vibrate with great rapidity. Singular combats sometimes ensue between the males, but no fatal issue occurs. . A subg<tnus established by M. Rafinesque, that of TESSAROPS, Appears to us to approximate closely to the following one in most Qf its characters and habits, but to be widely removed from it, if there be no mistake, in the number of the eyes which is but four. See Ann. Gener. des Sc. Phys., VIII, P· 88. A second subgenus, which also is only known to us by description, is the PALPIMANus, Duf., Described by M. Dufour in the Ann. des Sc. Phys., V, lxix, s, and which appears to him to be intermediate between Eresus and Salticus. The disposition of the eyes is about the same as in the first of these two subgenera. The ligula is similarly triangular and pointed, and the jaws are still dilated and rounded at the end; but according to M. Dufour, th ey are inclined and not straight like those of the Eresi. The terminal joint of the anterior tarsi is in· serted laterally and has no hooks. He describes one species, the Palpimane bossu. It never jumps, walks slowly, and is found under stones in Valencia, whet·e, however, it is extremely rare. A new species has been discovered by M. Lefevre in Sicily, which appears to me to belong to this genus. In the two following subgenera there are always eight eyes; the jaws are straight. EnEsus, Walck. Four eyes forming a small trapezium ncar the middle of the ante· rior extremity of the thorax, the other four on its sides forming a similar but much larger figure. The ligula is triangular an~ point· ed. The tarsi are terminated by three hooks( 1 ). ( 1) Eresus cinnaberinus, Walck. ; .llranea quatuor-guttata, Ross., :Faun. Etrusc., ll, 1, 8, 9; Coqueb., Ulust.

The thorax of some is very thick and sloping, (en talus) and much inclined at base. Salt. Sloanei; .!lranea sanguinolenta, L. Black; a white line formed by down on each side of the thot·ax; the abdomen of a cinnabar-red, with an elongated black spot on the middle of the back. South of France, on stones( 1 ). The thorax of the others is much flattened, insensibly sloping at its base. Sometimes their body is simply oval, and furnished with hairs or thick down; the legs short and robust.
