MANN: ANTS OF YUK BRITISH SOLOMON ISLANDS. 329 



Described from females and workers from t-\vo small colonies that 

 contained less than a dozen workers each. 



In the very feel)ly impressed mesoepinotal suture, the sharply 

 angulate pronotal humeri and in sculpture, fovcaceps and the closely 

 related punctata Vieh. from New Guinea differ markedly from the 

 other Papuasian species. V. punctata is larger than fovcaceps and 

 differently colored and has the petiole and postpetiole similar to 

 subtilis Emery subsp. magna Viehmeyer. In that form, according to 

 Viehmeyer's description, the postpetiole is somewhat broader than 

 the petiole and has strongly convex sides. In foreaceps it is t\\'ice as 

 broad as the petiole and the sides are nearly straight.
