HYMENOPTERA 



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. 



Pseudodicthadia : female only known, possibly that of Efiton. 



Cheliomyrmcx : workers and soldiers only known. 



AeAiictns — t\\e male, TypJdatta = worker: ^unknown. 



Bhogm.us : male ; female unknown. (According to Emery 

 the worker is very small and like Alaopoiic.) 



Anomma : only worker known ; male probably a Dorylus. 



Dorylvs = male ; Dicthadia = 5 : Alaopone and Typldopone — 

 workers. 



Sub-Fam. 6. Amblyoponides. — Ahdomen destitute of distinct 

 pedicel ; the articulutio/t het'ioeen the first and second 

 segments heliind the true petiole being broad. 



AVe follow Fore] in separating Amblyopone 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 \\\\\ 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 

 (Thynnides, e.g.). Little is known of these 

 Insects, though they are widely distri- 

 buted. Amblyopone is found in Australia 

 and New Zealand ; the allied genus

occurring even in Europe. The social 

 life is believed to h& imperfect, and the habits subterranean and 

 sedentary. 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. 



Association of Ants with other kinds of Insects. — We 

 have already alluded to the fact that a few species of ants are
