62 Mr. F. O. P. Cambridge — A Revision 



Tableau, p. 28 et seq., 1805, when he withdrew under 

 'Ihomisus all these si)ecies except emarginata and venatoria, 

 Linn. 



Aranea emarginata was, however, withdrawn by Walck- 

 enaer subsequently, in Faun. Frauijaise, p. 74 (1820), under 

 Thomisus, thus leaving Aranea venatoria, Linn., as the type 

 of the genus. 



Type, Heteropoda venatoria (Linn.), 1766. 



MisUMENA, Latreille, 1804, Nouv. Diet. xxiv. p. 135, col. 2, 

 line 2. 



One species alone is included by Latreille — Aranea citrea, 

 Ue Geer, which is Araneus vatius, Clerck, 1757 ; the latter 

 name having priority. 



Type, Misumena citrea^=vatia (Clerck), 1757. 



MiCROMATA, Latreille, 1804, Nouv. Diet, xxiv. p. 135, col. 2, 

 line 6. 



Four species were originally included, namely those under 

 " Les Grottiformes," by Walckenaer, Faun. Par. p. 225: — 

 (1) A. accentuata, \Valck. ; (2) A. smaragdula, Fabr. ; (3) 

 A. ornata. (4) A. rosea, Clerck. 



Out of these Walckenaer (Tableau, 1805, p. 39) selected 

 A. smaragdula, A. ornata, and A. rosea, and refers them to 

 his new g(^nus Sparassus; and later, in the same work p. 41, 

 he refers ^1. accentuata to Clnbiona. 



This Walckenaer, however, had no right to do, and accen- 

 tuata being the last species left in, naturally becomes the type 

 of the genus Micromata. 



In 1810 Latreille himself selects A. smaragdula as the 

 type of the genus, but this he had no power to do. He had 

 to be content with the species Walckenaer left in. 



Thorell says in this connection, ' Europ. Spid.' p. 176, 

 that " Microvimata includes ' Les Grottiformes,' Walck., and 

 A. accentuata, which is placed there by mistake." For 

 Latreille afterwards obviously wished Micromata to apply to 

 the three species referred by Walckenaer to Sparassus, since 

 he quotes his own previous generic name as a synonym of 

 Walckenaer's geims. 



One might equally well insist that all the tiiree species 

 originally limited by Latreille to Aranea were placed there 

 by mistake (as two ot them undoubtedly were), for later on 

 Latreille definitely selects Araneus domeslicus, Fabr., as the 

 type of Aranea, a species not included in his own previous 

 limitation of the genus.
