1920] Wheeler — Suhfamilies of Formicidae and Other Taxonomic Notes 53 



cidse. It is clear, nevertheless, that not only the Ponerinse and 

 Myrmicinse but also the Formicinse are to be referred to Lepeletier 

 (1836), who called them respectively the tribes Ponerites, Myrmi- 

 cites and Formicites, the last, like Mayr's subfamily Formicidae, 

 being made to include both the modern Dolichoderinae Forel and 

 Formicinse (Camponotinse Forel). 



The phylogenetic relations of the seven subfamilies, as under- 

 stood at the present time, are indicated in the accompanying dia- 

 gram (Fig. 3). For taxonomic purposes they may be most con- 

 veniently arranged in the following linear sequence: 



Family Formicidae Latreille (1910). 



Subfamily 1. Dorylinae (Leach 1815) 



2. Cerapachyinae (Forel 1893) 



3. Ponerinae (Lepeletier 1836) 



4. Pseudomyrminae (Emery 1899) 



5. Myrmicinae (Lepeletier 1836) 



6. Dolichoderinae (Forel 1878) 



7. Formicinae (Lepeletier 1836) 



In conclusion I may add that while working on the ants of the 

 Belgian Congo and constructing dichotomic keys for the identi- 

 fication of the genera and subgenera of the world, I have beea led 

 to adopt the following new names based on previously described 

 species : 

 Phrynoponera gen. nov. (Genotype: Bothroponera gahonensis Ern. 



Andre) 

 Viticicola gen. nov. (Genotype: Sima tessmanni Stitz) 

 Macromischoides gen. nov. (Genotype: Macromischa aculeata 



Mayr) 

 HypocTT/ptocerus subgen. nov. (Subgenotype: Formica hcemorrhoi- 



dalis Latreille) 

 Heteromyrmex gen. nov. (Genotype: Vollenhovia rufiventris Forel.) 

 Diodontolepis gen. nov. (Genotype: Melophorus spinisquamis Ern. 



Andre) 

 Pseudaphomomyrmex gen. nov. (Genotype: Aphomomyrmex emeryi 



Ashmead) 

 Cladomyrma gen, nov. {Genolype: Aphomomyrmex hewitti Wheeler).
