A LIST OF THE TYPE SPECIES OF THE GENERA AND NEW YOF 

 SUBGENERA OF FORMICILVE » BOTANlCAl 



OARDBN. 



By William Morton Wheeler 



(Presented by title before the Academy, 16 October. 1011) 



Although at the present time the taxonomy of the Formicidse is in 

 much less confusion than that of many other families of Hymenoptera, 

 there is nothing to indicate that this fortunate state of affairs will sur- 

 vive the present generation of conservative myrmeeologists. And, as it 

 is very generally conceded that confusion in taxonomy often arises from 

 a failure to recognize generic types, it seems advisable to publish a list 

 of these for the Formicidae. This is the more urgent, because Shuckard, 

 Emery and Bingham are almost the only authors who have expressly 

 designated type species of these insects. Being as firmly convinced as 

 Emery and Forel that the subgenus as well as the subspecies and variety 

 is, at least heuristically, a useful and valid category, I have recognized 

 the subgeneric types as such in the following list and have not followed 

 the example of those entomologists who, in similar lists, either ignore the 

 subgeneric category or throw all or most subgeneric names into the 

 synonymy. I have verified nearly all the bibliographic references cited 

 below, but for a few of them from obscure and antiquated sources I have 

 had to rely on Dalla Torre's "Catalogus Hymenopterorum." The list of 

 genera and subgenera both living and fossil is, I believe, complete up to 

 June, 1911.
