ten Olous or Olœus — that on that account alone it ought to be dis- 
carded. Ocypete, as the genus Heteropoda has been denominated by C. 
KocH, is a name already in 1815 assigned by LEACH to a genus of Acari. 
It is with doubt that I inelude this genus among those of Europe. 
Of the four species of Olios or Ocypete stated to belong to the European 
Fauna, one, the Ocypete tersa C. Kocu ?), is undoubtedly identical with Spa- 
rassus Argelasü, of which species I have found a specimen at Nizza, and 
have received another from Spain from Mr. Smon. The second, Ocypete 
vulpina (HAHN) C. KocH, described by HAEN as an Æpara, has according 
to KocH ?) its front row of eyes evidently curved backwards, and is there- 
fore surely a Sparassus (WALCK.) NOB. The third species, which, as well 
. as the preceding, is unknown to me, Olios spongitarsis (DUF.) WALCK. ?), 
is referred by DUFOUR *) to Micrommata (Sparassus WALCK.), and probably 
also belongs to Sparassus NOB. A fourth species, from Naples, described by 
CANESTRINI and PAVESI 5), is called Ocypete nigritarsis: it is perhaps also a 
Sparassus. |

The typical European species is to me unknown. — In a species 
from Asia Minor (Caramania), belonging to the ”3" Fam. Les Apharteres” 
of the genus in WALCKENAER (Ins. Apt., I, p. 548), and which I have re- 
ceived from Count KEYSERLING, the claws differ in appearance from those 
of all other Thomisoide known to me. They are indeed very long and 
slender, like those of the Philodrominæ in general, but they are pretty wnz- . 
formly curved, not straight the greatest part of their length, and entirely 
destitute of teeth. Under the claws are two strong, very thick claw-brushes, 
the hairs of which are long and fine, slightly dilated at the end, as in
