Pheidole megacephala, (Fabricius) ^HNS

Niangara, [[worker]]; Akenge, [[queen]]; Stanleyville, [[queen]]; Banana, [[soldier]], [[worker]] (Lang and Chapin); Zambi, [[soldier]], [[worker]], [[queen]] (Bequaert and Lang); Matadi, [[soldier]],[[worker]]; Thysville, [[worker]]; Boma, [[soldier]], [[worker]], [[queen]]; Malela, [[soldier]], [[worker]], [[queen]] (J. Bequaert). All these specimens belong to the typical form of this well-known tropicopolitan pest. I have been unable to recognize among it If Forel's subspecies nkomoana, originally described from the vicinity of Stanleyville. In the colony taken at Zambi by Lang and Bequaert there are several specimens of an interesting Microdon larva, which is figured and described in Part VI. The female specimens from Akenge and Stanleyville, five in number, were taken from the stomach of a toad (Bufo polycercus) and a frog (Rana, mascareniensis).
