1921] Emery — Specif c Names Repeated m Genus Formica 25 



on the assent of the majority of entomologists, at least in conti- 

 nental Europe. 



I ha^'e carefully gone over the seventh volume of the "Catalogus 

 Hymenopteronum'' of Dalla Torre, in quest of names of the Lin- 

 nean genus Formica which have been repeated, and have found the 

 following interesting particulars: 



F. longipes Latr. (1802), Fheiclole, has priority over F. lon- 

 gipes Jerdon (1851), Flagiolepis, and F. longipes Gerstsecker 

 (1858), Camponohis. Through my attribution of Latreille's spe- 

 cies to the genus Pheidole, Ph. longipes Pergande will have to take 

 the new name, Ph. grallipes, proposed by Wheeler. 



F. pilosa Olivier (1791), synonym of Camponotus fulvopilosus 

 De Geer, has priority over F. pilosa F. Smith (1857), Camponotus 

 (Colohopsis) -= Colohopsis puhescens Mayr {nee Fabricius) = G. 

 (Golohopsis) leonardi Emery (1889). This species should take the 

 latter name. 



F. pallens Le Guillou (1841) = Camponotus sp., near chloroticus 

 Emery, has priority over F. pallens Kylander (1849), Camponotus. 

 The latter should take a new name. I propose C. nijlanderi. 



F. fhoracica Olivier (1791), genus? has priority over F. tho- 

 tacica Fabricius (1804), Camponotus. This case is identical with 

 tlie homonym.ies of Leach's species and of subsequent authors, noted 

 ai: the beginning of this article. I therefore propose that G. thora- 

 cicus Fabr. be retained. 



Nearly the same state of affairs is encountered in the following 

 cases : 



F. ahdominalis Latreille (1802), genus? Formicinarum seu Db- 

 lichoderinarum, and F. ahdominalis Fabr. (1804), Camponotus. 



F. hadia. Latreille (1802), Pogonomyrmex, and F. hadia F. Smith 

 (1857), Camponotus. 



F. carinata Fabricius (1804), Polyrhachis, and F- carinata 

 Brulle (1840), Camponotus. 



F. erythrocephala Fabricius (1775), Leptomyrmex, and F. ery- 

 throcepkoJla Christ, Camponotus. 



F. fervens Drury (1782), Atta, and F. fervens F. Smith, Cam- 

 ponotus. 



F. foetida Linne (1758), Olivier (1791), Neoponera, F. foetida
