WHEELER, ADDITIONS TO FORMIC I DA^ 79 



Formica L. — Formica rufa L. is given as the type of this genus by 

 Girard (Traite Elem. d'Ent., II, p. 1011. 1879). 



Gnamptogenys Eoger. — My designation of Ectatomma concinnum F. 

 Smith {nee Mayr) as the type of this subgenus is erroneous. Emery has 

 rightly selected G. tornata, the first of two species described by Eoger. 



Holcoponera Mayr. — Now ranks as an independent genus. 



Labidus Jurine. — According to Mr. Rhower, Latreille designated L. 

 latreillei Jurine (=Eciton (Labidus) coecum Latr.) as the type of this 

 subgenus as early as 1810. 



Leptothorax Mayr. — Emery selects L. clypeatus Mayr as the type of 

 this genus, both because it was the first species described by j\Iayr and 

 because L. acervorum Nylander has already been made the type of the 

 subgenus Mychotliorax by Ruzsky. 



Myrmecia Fabricius. — Shuckard (Hist. & Nat. Arrang. Ins., p. 173. 

 1840) designated Formica gulosa Fabr. as the type of this genus. 



Myrmica Latreille. — Girard designated Formica rubra L. as the 

 type of this genus (Traite iBlem. d'Ent., II, p. 1016. 1879). 



Oecodoma Latreille. — Formica cephalotes L. is designated as the^ 

 type of this genus by Shuckard (Hist. & Nat. Arrang. Ins., p. 174. 

 1840). 



Rhytidoponera Mayr. — This now ranks as an independent genus. I 

 selected Ectatomma metallicum. F. Smith as its type. Emery designates; 

 E. araneoides Le Guillou {^rugosum F. Smith) (Gen. Insect., Fasc. 

 118. 1911), because it is the first species cited by Mayr and because he,. 

 Emery, had previously (1879) based the subgenus Chalcoponera on E. 

 metallicum. I do not regard the first reason as cogent; the second is, of.' 

 course, valid and sufficient. 



Tetramorium Mayr. — Formica ccespitum L. is designated as tlie type 

 of this genus by Girard (Traite :filem. d'Eni, II, p. 1016. 1879). 



Trigonog'aster Forel. — Through a blunder of my amanuensis or of 

 the printer the type of Trighjphothrix is repeated under this head. The 

 correct t3^pe is Trigon^gaster recurvispinosa Forel.
