1V^\ I ^\'JleeIer — Emery's Suhgenera of Genus Camponotus 17 



no one had seen lit to study heretofore, have been scrutinized. In 

 Emery's dassiiication only five of the subgenera are represented 

 in l)oth hemispheres, whereas 11 include only !N"ew World, and 

 19 only Old World species. Unfortunately, a certain amount of 

 confusion has lieen introduced by Emery's overlooking my desig- 

 nations of the types of ForeFs subgenera. It becomes necessary, 

 therefore, to discuss very briefly the subgeneric names that are 

 affected by this oversight. These are listed in the following para- 

 gra])hs, together with the cases in which Forel's types are invali- 

 dated by ray previous designations : 



Subgenus Camponotus Mayr. When ]\Iayr established the genus 

 Cainjonotus in 1861, he designated no type but placed Formica, 

 ligniperda Latr., first on his list of species. Just as he had placed 

 it first in the genus Formica in his work on the Austrian auts 

 (185.5). Bingham, perhaps for that reason, selected ligniperda as 

 the type of Camponotus in 1903, ignoring the fact that Forel and 

 Emery had long regarded this ant as a mere sub-species of hercu- 

 leanus L., which they therefore cite as the genotype. I am not 

 aware that our codes make any provision for such cases. 



Subgenus Myrmothrix Forel. I designated Formica ahdominalis 

 Fabr. as the type (1913), but Forel chose F. rufipes Fabr. (1914). 

 Both are retained in the subgenus as accepted by Emery. 



Subgenus Myrmolophus Emery. Emery has split this subgenus 

 off of Forel's Myrmepomis and based it on the Neotropical Formica 

 sericeiventris Guerin, leaving the remainder of the species, which 

 are African and jMalagasv, in Myrmepomis. I had designated 

 sericeiventris as the type of Myrmepomis in 1913, and Forel had 

 cited the Ethiopian F. fulropilosus DeGeer as the type in 1914. 

 As the latter designation is invalid, Myrmolophus becomes a syno- 

 nym of Myrmepomis, and it is necessary to replace Emery's name 

 for the Old World species. I propose the name Myrmopiromis 

 nom. nov. 



Subgenus Myrnwtarsus Forel. I designated Formica misiura F. 

 Smith as the type of this subgenus, whereas Forel selected F. irri- 

 iahiUs F. Smith. Both are included in the group as emended by 

 Emery. He includes also F. quadrisectus F. Smith, which was 

 cited by Forel as the type of Myrmophyma. Since I had previously 

 designated Camponotus capito Mayr as the type of the latter genus,
