62 Mr. F. O. P. Cambridge—A Revision 
Tableau, p. 28 et seg., 1805, when he withdrew under 
Thomisus all these species except emarginata and venatoria, 
Linn. 
Aranea emarginata was, however, withdrawn by Walck- 
enaer subsequently, in Faun. Frangaise, 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. Dict. xxiv. p. 135, col. 2, 
line 2. 
One species alone is included by Latreille—Aranea citrea, 
De Geer, which is Araneus vatius, Clerck, 1757; the latter 
name having priority. 
Type, Misumena citrea=vatia (Clerck), 1757. 
Micromata, Latreille, 1804, Nouv. Dict. 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, Walck.; (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 genus Sparassus ; and later, in the same work p. 41, 
he refers A. accentuata to Clubiona. 
This Walckenaer, however, had no right to do, and accen- 
tuata being the last species left in, naturally becomes the type 
of the genus ALicromata. 
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, ‘ Kurop. Spid.’ p. 176, 
that “ Micrommata 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 genus. 
One might equally well insist that all the three species 
originally limited by Latreille to Aranea were placed there 
by mistake (as two of them undoubtedly were), for later on 
Latreille definitely selects Araneus domesticus, Fabr., as the 
type of Aranea, a species not included in his own previous 
limitation of the genus.
