APPENDIX, 



We give below definitions of those genera which have 

 been formed since the completion of the precediDg paper. 

 Those of Mr. Simon and Count Keyserling we have trans- 

 lated with their notes. We wish, also, to refer to a genus 

 which had heretofore escaped our notice, and of which we 

 have not yet the definition. This is Chalcoscirtus Bertkau, 

 formed for Calliethera infima E. Sim., cf. Ver. d. Nat. Ver., 

 XXX, 1883, p. 207. 



PSEUDICIUS SIMON. 1885. 



Syn.: Attus auct (ad part.). Dendryphantes E, Sinn., Ar. Fr., Ill (ad part. 

 eucarpatus, etc.) + Calliethera E. Sim,, Ar., Karth., 1884 (ad 

 p. icioides). Pseudicius E. Sim, Faune Arach. deFasie Merid., 

 Bulletin de la Soc. Zool. de France, t. x. 1885. 



Related to the genus Icius E. Sim., differing in having the eye area par- 

 allel above, and the falces in $ and $ not grooved in the outer sides; 

 tibiae I and II unarmed, or with one spine (P. hadius), or provided with 

 two minute spines on the inner side; tibiae and metatarsi III and IV un- 

 armed, (excepting with the ordinary terminal spines); 3 with femur and 

 tibiae I very stout. 



I believe it necessary to create this genus for a certain number of spe- 

 cies whose characteristics are intermediate between those of Icius, and 

 tho&e of Dendryphantes and Calliethera, but which does not agree entirely 

 with any one of these. The cephalothorax is long and low as in Calli- 

 ethera and Icius, the first row of eyes is equally straight, this being tho 

 point which separates these genera from Dendryphantes, the ocular qua- 

 drangle is parallel above, as in Calliethera; the armatui'e of the anterior 

 legs is very peculiar; the tibiae are unarmed with the exception of one or 

 two small internal spines on the first pair, but the metatarsi have two pairs 

 of small spines. The integument is covered with simple hairs, never with 

 scales. 



This genus has for its type P. {Dendryphantes) encarp>atus Walck. ; it in- 

 cludes beside. P. badius E. Sim., P. picaceus E. Sim , from tlie south of 

 Europe, and P. (Calliethera) icioides E. Sim., from Khartoum.
