segments prominent, forming a cone which is bent forward and has a base 

 occupying the posterior 5 of the ventral surface of the first gastric segment. 

 Sting well developed. Legs rather long and robust. 



Mandibles, appendages and body opaque, with the exception of the gaster 

 which is shining. Mandibles finely striated. Head, thorax and pedicel densely 

 punctate or granular, the surface becoining more uneven on the epinotum, 

 petiole and postpetiole. Upper surface of postpetiole almost rugulose. Gaster 

 very finely punctate. 



Body and appendages covered with rather long yellowish pubescence, 

 interspersed with longer, suberect hairs of the same color. 



Rich ferruginous red, gaster somewhat paler, mandibular teeth, edges of 

 clypeus and frontal carinas blackish. 



Female (dealated). Length 4.8 mm. 



Resembling the worker except in the usvial sexual characters, namely, the 

 presence of the ocelli, the larger eyes and the structure of the thorax. The wing 

 insertions and thoracic sutures are black. The ventral tooth of the petiole is 

 in the middle of the segment as in the worker. The first gastric segment is 

 distinctly broader than the postpetiole. 



Described from single worker and female specimens collected by- 

 Mr. H. Sauter, the former at Okayama, Bizen, the latter at Kamakaur 

 on the Sagami Gulf "under drift-wood on the sea-beach.' ' This species, 

 which I take pleasure in dedicating to my old friend Professor Sho 

 Watase of the Imperial University at Tokio, very closely resembles 

 the other known species of the genus, namely the three Mediterranean 

 species 5. europcea, algirica, and inayri, and the two North American 

 species melina and pergandei. The Japanese species may be dis- 

 tinguished from all of these except 5. algirica by its flatter postpetiole, 

 from algirica by the position of the ventral petiolar tooth, which is 

 in the middle and not at the anterior end of the segment. 



2. Pachycondyla (Ectomomyrmex) japonica Emery. 



Emery, Rendic. R. Accad. Sci. Tst. Bologna, Ann. 1901, p. 12 (sep.) i, $ 



This ant, of which I have seen no specimens, was described from 

 the Island of Tsushima, between Japan and Corea. 



3. Pachycondyla (Pseudoponera) sauteri sp. nov. 

 Plate XLI, Fig. 66, a. 



Worker. Length 3-3.5 mm. 



Head longer than broad, narrower in front than behind, with straight poste- 

 rior border. Eyes very small, of one or two ommatidia, situated about ^ the 

 distance from the anterior to the posterior corner. Mandibles broad, tri- 

 angular, 7-8-toothed, with rather straight outer borders. Clypeus short.
