" Ntin\')>c, Blackw. (seiisu restricto)." l^it the nctioii of 

 elimination had already set in, and left the type higli and 

 drv, so that this selection becomes void. 



Nearly every author had ignored iilackwall's mnie Xerieuc. 

 nntil 1894, when Simon restored it, but anisigiicd to it as its 

 type N. fusca, Blackw,, a species not originally include 1 in 

 the genus. 



Type, Nen'ene marginaf a, l^lackw.,= /y. clutJinda, Sund. — 

 Europe. 



AiJRECERUS, Simon, Hist. Nat. Ar. p. 197 (1864). 



Two species were includfid in this genus originally: — 

 (1) A. rantelinus, C. Koch ; (2) A. monoceros, Wid. 



A. wonoceros, Wid., was witlidrawn by Simon under his 

 new genus Proaopotheca (Ar. Fr. v. p. 829, 1884), h-aving 

 camelhius as the type. This is undoubtedly identic;il with 

 WaJclcenmrln acuminata, Hlackw. (feniale). 



Type, Arrecerus camelinus (C. Koch) (= W. acuvu'natay 

 lilackw.). — Germany. 



ViDERius, Simon, Hist. Nat. Ar. p. 196 (1864). 



Two species were originally referred to this genus : — 

 (1) V. cucuUatus, Koch ; (2) V. tibialis, Koch. 



The first was taken out as the type of Ithyomma by Bertkau 

 in 1884, being the only species referred to the genus, leavitig 

 the second as the type. This species is now regarded as 

 identical with antica, Wid. 



Type, Viderius tibialis (Koch) = V. antica (Wid.). — 

 Germany. 



GONATIUM, Menge, Preuss. Spimi. p. 180 (186S). 



Two species were originally referred to this genus : — 

 (1) G. cheh'ferum, Wider; (2) G. isabe/linum, C. L. Koch. 



This genus has never been broken up, nor had the type 



been selected until 1884, when Simon selected rubens, Blackw., 



as the type (Ar. Fr. v. p. 546, 1884), a species which is 



regarded by both Thorell and Simon as identical with clitli- 



ferum, Wider. 



Tvpe, Gonatium chelifemm (Wider), 1834=^/. riibeus 

 (Blackwall), 183;-i.— Europe. 



LyCvENA, Sundevall, Kongl. Vet.-Akad. Handlingar (Act. 

 Holm.), p. 2Go (1833). 



A sin'^lc species only was referred to this genus originally.
