wheeler: the ants of borneo. 95 



Described from two specimens taken by Mr. John Hewitt at Kuch- 

 ing. 



In the shape of the head, mandibles, and antennae this species 

 approaches S. viocsaryi Emery of Papuasia, but the mandibles are 

 decidedly shorter and the pilosity and arrangement of the spongiform 

 appendages of the petiole are very different. The Bornean species 

 is also related to four Javanese species recently described by Forel 

 {S. kraepelini, koningsbergi, signcae, and ehhae), but is smaller than any 

 of them. It can be readily distinguished from kraepelini and ko7iings- 

 bergi by the well-developed, spiniform, preapical tooth of the mandi- 

 bles. S. signeae possesses a translucent inner border to the mandibles 

 and an emarginate clypeus and in cbbae the preapical tooth is only 

 slightly longer than broad, the antennal scapes are shorter, the first 

 funicular joint not longer than broad, the hairs are club-shaped and 

 the color is deep ferruginous. 



*123. Strumigenys bryanti, sp. nov. 



Female. Length, 4.8 mm. 



Slender; head fully If times as long as broad, its posterior border deeply 

 and semicircularly excised, the sides gradually converging to the rather large, 

 convex eyes, the preocular portion 1 § times as long as broad, with subparallel 

 sides; vertex very feebly convex, the posterior lobes depressed and flattened. 

 Mandibles fully | as long as the head, straight, flattened, with parallel borders, 

 very slightly narrowed at their insertions, sinuately excised at the inner border 

 just back of the two strong, subequal, spiniform, apical teeth. Preapical 

 tooth absent. Clypeus flattened, as long as broad, its anterior border entire. 

 Antennae very slender; scapes reaching to the posterior fourth of the head; 

 last funicular joint much shorter than the remainder of the funiculus and some- 

 what longer than the preceding joint, joints 2 and 3 subequal, as long as broad, 

 together a little more than half as long as the first joint. Thorax distinctly 

 narrower than the head, a little more than twice as long as broad, very high 

 and convex in the region of the mesonotum and scutellum, the epinotum low 

 with short horizontal base and long vertical declivity, meeting it at a right 

 angle; spines reduced to rectangular flat teeth, each continued as a trans- 

 lucent, spongiform plate down the side of the declivity. Petiole three times 

 as long as broad, broader behind than in front, with straight sides, the node 

 low and rounded, in profile gradually passing into the peduncle, its posterior 

 border with spongiform appendages and its ventral surface behind with a 

 median spongiform lamella. Postpetiole subcircular, as long as broad, 

 broader than the petiolar node, only its dorsal surface exposed, the remainder 

 embedded in spongiform material, with a long, flat plate of the same substance
