makes no new penus incluJinfj any of the species originally 

 inchulod under PhruroUtltus. Under Micaria VVestring places 

 (1) fuhjens, Walck., and (2) piih'caria, Sund., neitlier of 

 these, either directly or through a synotiyni, having been 

 nferred to the original genus. In 18G9 (Europ. Spid. p. 140) 

 Thorell selected /^s//ya«, Koch, as the type o'l Pit rural ithus. 

 Type, Phrurolithus festivas (C. L. Koch), 1835, — Europe. 



ZiLLA, C. L. Koch, Deutsch. Ins. (Panz.ir) Het't 124, 125 

 (1834) (sec. Inde.K Animalium, MS.). 



Two species were originally referred to this genus : — 

 (1) Z. aWiniacuIa, C. L. Koch ; (2) Z. monfana, C. L. Koch. 



The grouj) was not broken up nor was the type selected 

 until 1837, when Koch hinisflf selected, on p. 5 of the * Ueber- 

 sicht,' under Zilla, " Typ. Zilla albimacula, Koch, Deutsch. 

 Ins." This species is, sec. Thorell, Simon, and Kulczynski, 

 identical with diodia, Walck., this latter name having 

 priority. 



Thorell, in 1869 (Europ. Spid. p. GO), saj's : — " A.S type 

 for the genus Zilla, Koch, it is true, gives Z. alhimacubi [Ep. 

 diodia^ Walck.), but as we feel ourselves obliged to refer that 

 species to the genus Epeira^ we have assumed as typical 

 species Zycfia adophylla (Walck.) = Z^ x-notata (Clerck), 

 which appears to us best to express the peculiarities of the 

 genus, is the first species of the genus described, and has 

 since been by Koch himself assigned to Z/7/a." 



But neither Thor( 11 nor Koch himself can, according tix 

 the customary views of systematists, alter the published and 

 selected type any more than Koch could alter the name ZUla 

 itself in a subsequent publication, and, in any case, calophylla^ 

 Walck., was not included when Zilla was first founded.

A single i.ame only was originally referred to this genus : — •" 

 Aram a calophylla, VValck. Faune Par. ii. p. 200. 



Under this name, however, two species were involved (cf. 

 Koch, Thorill,anil Simon) — x-notata, Glerck (=^4. litterata,- 

 Ulivi(r), and Eucharia atrica, C. L. Koch. Botli these 

 species were included by C L. Koch under Zytjia, the male 

 ol the latter on fig. 17, the female of the former on figs. 18, ll>. 



Tills male Koch, in 1844, renamed atrica, reserving tlw 

 name catophylla for the female, referring the former to his
