as formulated by Forel should be reversed, that Metapone 

 should be regarded as belonging to the subfamily Myrmicinas 

 and that the resemblance of the genus to Pseudomyrma and 

 Sima is due to genetic relationship and not merely to con- 

 vergent adaptation. I nevertheless accept Forel's section 

 Promyrmicinas but as a division of the Myrmicinae and extend 

 its scope to include two tribes, the Metaponini and Pseudo- 

 myrmicini. " Apparently Emery reached this conclusion as a 

 result of regarding Metapone as closely related to the African 

 Pachysima aethiops Smith and especially to P. latifrons Emery. 



As Forel's knowledge of the male and female of M. greeni 

 was restricted to a study of pupal specimens, he could give no 

 account of the venation of the anterior wings. In 1913, 

 however, he described a second species, M. sauteri, from a 

 female specimen taken in Formosa* and figured the fore wing, 

 which has an open radial cell and a single cubital cell. 

 This led him to incline to Emery's view and to suggest a 

 resemblance- between Metapone and the Myrmicine genus 

 Liomyrmex. 



In 1915 Forel described a third species of Metapone from 

 Queensland, M. mjdbergi\, and I have since described two 

 species, M. bakeri, from a female specimen taken in the Philip- 

 pines J and M. hewitti, from male specimens taken in Borneo §. 

 The latter species showed that the male Metapone really has 

 12-jointed antennse and that Forel had evidently overlooked the 

 second funicular joint in the male of greeni. Still more recently 

 I have found two undescribed species, one from New South 

 Wales and one from Queensland, among material sent me 

 for study by the Museum of South Australia. Thus the 

 •genus Metapone, as at present known, comprises seven species. 



Concerning the habits of these ants very little has been 

 recorded. Mr. E. E. Green took the specimens of the type 

 species "from galleries in a decayed branch, which was also 

 infested by two species of termites." And Forel adds: "It 

 lives, therefore, like Cylindromyrmex, in wood, with termites.
