MANN: ANTS OF THE BRITISH SOLOMON ISLANDS. 389 



to the one described by Wroughton (Journ. Bombay nat. hist, soc, 

 1892. 7, p. 37). 



My specimens agree perfectly with Mayr's description and with 

 workers from the Phihppines. 



122a. PoLYRHACHis (Cyrtomyrma) rastellata (Latreille), var. 

 FULAKORA, var. nov. 



Worker. Length 6.5 mm. 



A very large series of workers from many colonies agree with rastellata in 

 structure, having the pronotum broadest in front and with rounded humeri, 

 the epinotum entirely without spines and the lateral spines of the petiole well- 

 developed and acute, but differ in the color of the legs, which are very dark 

 reddish brown, instead of blood-red. This difference is constant throughout 

 the series and warrants this variety. 



Ysabel : Fulakora. 



Stitz (Sitzungsb. Gesellsch. nat. freunde Beriin, 1911, p. 381) describes 

 rastellata var. major as larger than the typical form and with dark 

 brown legs. He does not give the length. The humeri of his variety 

 are more angular than in rastellata. In var. fulakora they are rounded 

 as in the type form. The epinotum in fulakora is more convex in profile 

 rather similar to subsp. euryala F. Smith from Java as figured by Vieh- 

 meyer (Archiv naturg., 19i3, p. 52). Tijpe.— M. C. Z. 9,189. 



122b. PoLYRHACHis (Cyrtomyrma) RASTELLATA Latreille, subsp. 



UGiENSis, subsp. nov. 



Worker. Length 5.5-6 mm. 



The specimens from the eastern Solomons represent still another form of 

 this variable species, characterized by the shorter spines of the petiole, which 

 in some specimens have the lateral ones reduced to mere angles, and in the 

 color of the legs. The femora and the tibiae are reddish brown, with the bases 

 of the latter and the tarsi black. The antennae are black, except the extreme 

 tip of the last segment, which is brown. 



Nests are figured on Plate 2, fig. 1, 2. 



Ugi : Pawa. San Cristoval : Wai-ai, Parnua, Wainoni Bay. Three 

 Sisters: Malapaina.
