two longer and more slender teeth, which are longer than broad at their 

 bases. Postpetiole more rectangular than in greeni, nearly as long as 

 broad. Gaster much broader, nearly twice as broad as the postpetiole, 

 first segment nearly three times as long as the postpetiole. Lobes and 

 teeth on the ventral surface of the petiole and postpetiole precisely as in 

 greeni, also the teeth on the posterior tibiae and metatarsi, but the 

 femora, especially the anterior pair, twice as long as broad. Wings 

 with a single cubital cell, a discoidal and a long radial cell, the latter 

 slightly open at the tip; radial and cubital veins separating at the tip 

 of the cubital cell. 



Longitudinal striation of the head and thorax much as in greeni, 

 but somewhat coarser, the head less punctate. Petiole and postpetiole 

 not only punctate as in greeni, but also sharply longitudinally striate; 

 the striae on the petiole arcuate behind. Gaster shining, sparsely 

 punctate and feebly and finely coriaceous. 



Hairs sparse, reddish yellow, both erect and appressed on the 

 body; appressed hairs on the head and thorax very scarce. 



Black; antenna) and gaster dark reddish brown; tibias and tarsi 

 reddish; femora and coxae brownish. Wings brownish, with brown 

 veins and pterostigma. 



Type-locality: Sokutsu, Banshoryo District, Formosa (Hans 

 Sauter). 



4. Metapone leae sp. nov. 

 (Figs. 3 and 4.) 



Female. Length 6.5-7 mm. 



Head one and one-half times as long as broad, distinctly narrower 

 at the anterior corners than behind, the sides feebly convex and the 

 posterior border nearly straight; the upper surface very fiat, in profile 

 about two and one-half times as long as high. Mandibles convex, 

 their basal lobes large, their terminal borders with a series of five teeth, 

 smallest apically and largest basally. Clypeus flat, with a long pro- 

 jecting median lobe, which has a straight, transverse anterior border, 

 concave sides and acute comers. Eyes rather large, but evidently 

 smaller than in greeni and sauteri. Ocelli small, near the occipital 

 border. There is a longitudinal, impressed line, bordered on each 

 side by a ruga, representing the frontal groove, extending from the 

 posterior border of the clypeus to the anterior ocellus and growing 

 deeper posteriorly. Antennae rather stout, flattened; scape elliptical, 

 somewhat more than twice as long as broad; funiculus with 3-jointed 

 club, first joint as long as broad, joints 2-7 transverse, broader than 

 long, terminal joint about as long as the two preceding joints together. 

 Thorax elongate, subhexagonal, fully two and one-half times longer 

 than broad, very flat above, four times as long as high, broader through 

 the wing insertions where it is as broad as the head. Humeri of pro- 

 notum bluntly angular; mesonotum slightly concave behind, as broad 

 as long, with the scutellum on the same level as the base of the epi- 

 notuin, which is longer than broad, narrower behind than in front,
