a detailed description of the spider, which he from Walckenaeb's 

 description knew to be that author's F. bicolor, had in the mean 

 time sent specimens of it to Latreille, who recognized it as his F. 

 testacea (vid. Duf. , loc. cit. , p. 534); and thus the identity of the 

 two species, long ago assumed by Walckenaeb, was fully established. 

 As there is not the least doubt about what spider Latkeille intended 

 by his F. testacea, and as it may be considered as sufficiently cha- 

 racterized by the description of the genus coupled icith the notice con- 

 cerning the habitat of the species, it seems to me that there is no 

 reason for abandoning the older appellation testacea originally given 

 by Latreille and accepting the more recent name bicolor; and I 

 therefore call the species F. testacea Latb. 1810. — I have found 

 this spider common at Nice, and have also met with it at several 

 other places in Italy. — Walckenaer asserts (Ins. Apt., IV, p. 376) 

 that the claws of the mandibles are, according to the statement of 

 Dufoub, "finement et longuement pectines"; but this is of course a 

 mistake: it is the claws of the tarsi, of which Dufour says that they 

 are "finement et assez longuement pectine's". On these claws see 

 Thor., loc. cit.

In the male the femoral joint has on the outer side a coarse 

 protuberance, and is thicker between the basis and this protuberance 

 than between the protuberance and the apex; the patellar joint is 

 about as long as it is broad, not drawn out at the apex above into 

 a conspicuous tubercle; the tibial joint is somewhat broader than it 

 is long, rounded on the outer side, without any processes. The 

 bulbus, along its outer margin, exhibits a strong, long, black cal- 

 lus, the posterior end of which is so curved as to enter between the 

 lamina and patellar joint. The bulbus has on the inner side at the 

 base a broad lamina directed inwards, and immediately behind that 

 a stout, black, crooked spine; near the middle of the under side at 

 the base it exhibits a fine, curved, black spine. A long spine is seen 

 curving backwards round and under the extremity of the bulbus. The
