1931] Wheeler — Emery's Siibgenera of Genus Camponotits 19 



I propose Myrmocladoecus iiom nov., since all or nearly all the 

 species live in hollow twigs. 



Subgenus Myrnmmhljjs Forel. Here, too, difficulties arise owing 

 to the fact that Emery has restricted the name to American species, 

 I designated an East Indian species, Camponotus reticulatus Roger 

 as the type (1913), but Forel selected a Neotropical form, C. fasti- 

 gatus Roger. As Emery has placed reticulatus in Myrmotemnus, 

 the latter would seem to be a synonym of Myrmamhlys Forel (1913 

 and 1913), and the selection of a new name for Myrmamhlys 

 Emery (1920) is made necessary. For this I propose Neomyr- 

 mamblys nom. nov. I have already explained why the small group 

 of American species including sexguttatus must be retained as 

 Myrmnspliinda Forel {vide supra). 



Siil^genus Myrmorhachis Forel. Discussed above in connection 

 with Myrmacantha Emery. 



Subgenus Myrmeurynoia Forel. I designated Camponotus eury- 

 notus Forel as the type of this subgenus but Forel cites C. gilvi- 

 ventris Roger. Both are included in Emery's list of species. 



Subgenus Manniella subgen. nov. I propose this name for the 

 small group comprising the Cuban sphaericus Roger (subgenotype) 

 and its subspecies sphaeralis Roger. Mann has recently discovered 

 and described the maxima worker of these forms.^ Both Forel and 

 Emery include them in Myrmeurynota, whereas Mann assigns them 

 to Colobopsis. The structure of the head, pronotum, etc., of the 

 large worker is so aberrant that they cannot be included in these 

 subgenera, nor in Emery's Hypercolohopsis, Pseudocolohopsis nor 

 Paracolohopsis. 



The changes suggested above increase the number of subgenera 

 of Cam.ponotus to 36. • ~
