Westbing has only reproduced Sundevall's description of that 

 writer's S. formicarius; neither has Westbing, nor have I, seen a Swe- 

 dish specimen of this spider. — It is easy to see from De Geeb's 

 description, that C. Koch is mistaken in classing Ar. formicaria De 

 Geee under his S. formicarius Or Leptorchestes formic af or mis (Luc), 

 Thoe., and that De Geee's spider does not at all belong to Salticus 

 C. Koch 1837, but to Salticus Sund. 1833, that is, to the genus 

 called by C. Koch Pyrophorus and by Simon Pyroderes. That Ar. 

 formicaria De Geee is the same as Attus {Pyrod.) formicarius Walck. 

 et Sim., might on the other hand be doubted. In favour of the iden- 

 tity of these species may be adduced the circumstance, that the S. 

 formicarius found by Sundevall in Gotland is without a doubt the 

 same as Attus (Pyrod.) formicarius, as also v. Noedmann's statement 2 ), 

 that he had found "Pyroph. semirufus C. Koch" in Aland: it is hardly 

 probable, that here in Scandinavia, and so high up to the North, we 

 should have more than one species of this singular genus. Against 

 the assumption of their identity might be urged, that in Ar. formi- 

 caria De Geee (of which De Geee was acquainted with the female 

 only) the abdomen is stated to be "roux, avec des bandes noires et 

 deuxtdches blanches": in the two specimens of A. (Pyrod.) formicarius, 



1) "Fig. 1095" and "Fig. 1096" in this plate should change places.
