Type: Leptorchestes formiceformis Luc. 
Concerning Salticus (LATR.) SUND. see preceding genus. As type 
for Leptorchestes (Salticus C. KocH) I have taken LUCAS’ Attus formicæfor- 
mis, which is identical with Salticus formicarius C. Kocm. The right Sal- 
ticus formicarius (DE GEER) and SUND., is the same as Pyrophorus semirufus 
C. Kocn. 
The genus Synemosyna HENTZ answers properly speaking to Janus 
C. Kocx, but under the former name species have also been included, which 
belong to Leptorchestes, and perhaps even to Salticus SUND. Synemosyna 
formica HENTZ!), which appears to be typical for the genus, is a Janus, 
and it is therefore this latter name, which must give place to the older 
appellation Synemosyna: the name Janus is moreover already appropriated 
(see p. 36). 
In the typical species the claws are small, of quite an ordinary form, 
sinuated, with about 7 teeth gradually increasing in length on the inner 
and about 3 on the outer claw. The hairs of the claw-tuft are much dilated 
at the extremity. 
Gen. 3. EPIBLEMUM (Hzwrz). 1832. 
Deriv.: émígAque (èxé, on, Béllw, throw), that which is thrown on or over 
(in allusion to the animal’s swift motions, or the projecting mandibles of ©).
