British OHgocene Ants. 85 



epinotiim is spined. Part of the integument remains on the 

 liead and thorax in all three bits of rock, and the punctu- 

 ration is coarse and rugose as in Rhytidoponera, Stictoponera, 

 et al. The neuration of the wing is not very distinct, but a 

 discoidal and second cubital cell are present. The junction 

 between the thor;ix and gaster is not clear. 



Long 5 mm. • | iea d and thorax together 25 mm. ; discoidal 

 cell, which touches the second cubital cell, "5 mm.; first 

 cubital on discoidal *3 mm. ; second cubital at apex *2 mm. 



OHgocene at Gurnet Bay (Brodie). 



Holotype, (a. 12), I. 8744 (PI. V. fig. 1), and its counter- 

 part (a. 13), I. 9936; paratype, (a. 11), I. 9325 (PI. V. 

 tig. 2). All in Brit. Mus. 



Named after my friend Professor W. M. Wheeler, in 

 recognition of his splendid work on the ants of the Baltic 

 amber (1914). 



Tribe PoNElUNI, JForel.

Subgenus Mesoponera, Emery. 



Euponera {Mesoponera) crawleyi, sp. n. 



Head, thorax, scale, gaster, one antenna, and traces of 

 several legs present. 



The head is triangular but indistinct in detail, the jaws 

 and eyes not being indicated. The antenna is thickened 

 towards the apex. The scale is high and narrower at the 

 apex. The segments of the gaster fairly distinct, the first 

 segment not strongly constricted.

Holotype, T. 8675. in B.'ir. Mus. (PI. V. fig. 3). 



] have placed this specimen in Mesoponera with considerable 

 hesitation. It shows the lateral view and resembles specimens 

 of this genus when seen in profile. I have named the species 

 after my friend Mr. W. C Crawley, in recognition of kind 

 suggestions made by him concerning these difficult fossil ants. 



Mesoponera is widely distributed, occurring in Africa, 

 India, Australia, New Zealand, and America. 



Genus Poneea, Latreille. 

 Ponera minnta, sp. n. 



This small ant appears to me to be a Ponera. The head 

 is raised in front, one fore and one hind wing are present ;
