to suspect that the amber specimens, which I examined, may rep- 

 resent more than two very closely related forms. The worker 

 major of Cr. howardi shows that the genera Gesomyrmex and Di- 

 morphomyrmex are more closely related than was supposed. Nev- 

 ertheless, the gizzard of D. andei figured by Emery'^ is quite dif- 

 ferent from the gizzard of G. capperi figured by Andre. In the 

 former insect the organ is short and broad with short, terminally 

 reflected calyx-lobes, in the latter long and slender and more as in 

 Camponotus and Oecophylla. 



The thickened bases of the femora of G. howardi indicate that 

 this ant can jump like the large-eyed Gigantiops destructor Fabr. 

 of the Neotropical Region, and the rather feeble tarsal claws would 

 seem to indicate that it is not arboreal but nests in the ground.
