THE CANADIAN ENTOMOLOGIST. 381 



A SKELETON OF A NEW ARRANGEMEN T OF THE FAMILIES, 



SUBFAMILIES, TRIBES AND GENERA OF THE ANTS, 



OR THE SUPERFAMILY FORMICOIDEA. 



BY WILLIAM H. ASHMEAD, M. A., D. SC. 



Of the ten superfamilies recognized in my classification of the 

 Hymenoptera, all have been classified down to genera except the Ants, or 

 superfamily IV, Formicoidea, a very large and most difficult complex, and 

 rendered even more difiicult by the extraordinary number and diversity of 

 the sexes, there being sometimes several different forms to a single species. 



It has now been several years since I began working on this great 

 complex to bring it in harmony with the other superfamilies classified, and 

 my labours are nearly completed, as I only await the arrival of certain 

 exotic genera to perfect some of the generic tables. The work fills several 

 hundred pages of manuscript, and will make a large volume in itself, too 

 large to be published in any entomological journal or magazine, and as 

 the completed work cannot be published before next year, I desire to put 

 on record a skeletonized epitome of the arrangement, selecting for that 

 purpose the Canadian Entomologist, in which the classification of other 

 of the superfamilies were published. 



It will be noticed that I recognize as valid genera nearly all of the 

 subgenera of Mayr, Forel and Emery, and that I restore the genera 

 Monads, Roger, and Hypocli7iea, Mayr, suppressed by Emery and Forel 

 as synonyms of Dolichoderus^ Lund. All three are good genera. Dolicho- 

 derus, Lund, is not found in the United States, and our species so-called 

 belong to Hypoclinea, Mayr. Monads^ Roger, I know only from Mexico.
