I 80 HYMENOPTERA 



CHAP. 



The specimens of female Dorylides that have been detected may, 

 after fifty or sixty years of research, be still counted on the fingers. 

 As the greatest confusion exists in entomological literature 

 owing to the forms of a single species having been described as 

 two or three genera, the following summary of the principal 

 names of genera of Dorylides may be useful : 



Eciton = the workers, Labidus = male : ? unknown. 



J'fii-Hi/ixJirf/iitt/ii/ : female only known, possibly that of Eciton. 



Cheliomyrmex : workers and soldiers only known. 



Aenictus = the male, Typlilatt worker : unknown. 



Rliogmus : male ; female unknown. (According to Emery 

 the worker is very small and like Alaopone.} 



Anomma : only worker known ; male probably a Dorylus. 



Dorylvs = male ; Dicthadia = 9 : Alaopone and TypJilopone - 

 workers. 



Sub-Fam. 6. Amblyoponides. Abdomen destitute of distinct 

 IH'ilirf] ; f/ie articulation between the first and second 

 segments behind the true petiole being broad. 



"We follow Forel in separating Amblyorjone and a few allies 

 from the Ponerides, because the abdominal pedicel is more 



imperfect than in any other ants. It is, 

 indeed, very difficult to frame a definition 

 that will include the Amblyoponides 

 among ants, and at the same time sepa- 

 rate Formicidae and Scoliidae. Forel con- 

 siders the Amblyoponides to approach 

 closely to certain divisions of the Scoliidae 

 (Thyimides, e.g.}. Little is known of these

occurring even in Europe. The social 



life is believed to be imperfect, and the habits subterranean and 

 M'llmtary. The males and females are winged; the latter much 

 resemble the workers, which are nearly blind, and have a con- 

 siderable general resemblance to Anomma, in Dorylides.
