and Forel's designation is invalid, there can be no objection to 

 Emery's i^rocedure. 



Subgenus Myrnwsphincta Forel. I designated the Neotropical 

 Formica sexguitata Fabr. as the subgenotype, Forel the Malayan 

 F. cinerascens Fabr. P^mery has now transferred sexguttata to 

 his subgenus Myrmotemnus and has retained the name Myrino- 

 spJiincfa for the Malayan, Australian and Malagasy species. It is 

 clear that a new name is required for Myrmosphincta Emery 

 (1920). I propose Myrmosaulus nom. nov. 



Subgenus Myrtnophyma Forel. As already stated, I designated 

 Camponotus capita as the type, but Forel selected quadrisectus. 

 Emery also designates capita as the type. Forel's Myrmocamelus 

 becomes a synonym of Myrmopliyma, because he selected as its type 

 Formica epliippiwn F. Smith, which is merely one of a number of 

 Australian species closely related to capito. Thus owing to my 

 prior designation of the type of Myrmopliyma it is unnecessary for 

 Emery to violate the code of nomenclature (1913), according to 

 which genotypes are stable and cannot be changed. 



Subgenus Myrmosaga Forel. Here, too, there is a discrepancy 

 in the types selected, as I had designated Camponotus helleri Forel 

 and Forel had selected C. quadrimaculatus Forel. Both are in- 

 cluded in the subgenus as emended by Emery. 



Subgenus Myrmentoma Forel, This subgenus, established by 

 Forel in 1913, was in 1914 regarded by him as a synonym of Ash- 

 mead's Ortkonotomyrinex (1906). I had designated Formica lat- 

 eralis Olivier as the type of Myrmentoma in 1913, and Forel had 

 designated the same type for Orthonotomyrmex in 1914, overlook- 

 ing the fact that Ashmead had designated Formica sericea Fabr. 

 Emery has resuscitated Myrmentoma and defined it and OrtJionoto- 

 niyrmex more precisely. 



Subgenus Myrmepomis Forel. See Myrmoloplius, above. 



Subgenus Myrmacantha Emery. This is a synonym of Myrmor- 

 liachis, for in 1913 I designated as the sub-genotype of the latter the 

 Ethiopian Camponotus polyrliachioides Forel, which is closely re- 

 lated to C. aherrans Mayr designated as the type. Forel in 1914 

 selected the Neotropical Camponotus latanguhis Roger as the type 

 of Myrmorliaclm. Since Emery restricts the latter name to the 

 American forms it becomes necessary to replace it by a new term.
