Probably the most conspicuous ant in the islands. Foraging workers 

 were on nearly every tree examined. The colonies are in tree-cavities. 



114a. PoLYRHACHis (Myrma) relucens Latreille, subsp. Andro- 

 mache F. Smith, var. nesiotis, var. nov. 



Worker. 



Differing from subsp. andromache in having the legs darker in color, dark 

 red, with the femora in part and the tibiae infuscated and the tarsi black. 



Santa Cruz : Graciosa Bay. 



This variety, the only one of the relucens group found at Graciosa 

 Bay is exceedingly abundant and very large series were obtained, all 

 of which are constant in coloration. It nests in crevices of trees and 

 in hollow fern-stalks. Type — M. C. Z. 9,194.

Ysabel: Fulakora. 



Numerous colonies were found nesting in rotten logs. Some of the 

 cavities used as brood chambers were lined with silk. 



Pinned specimens are very liable to grease and many among my 

 series have the gaster black in appearance due to this, which hides the 

 rich golden pubescence characteristic of the subspecies.
