In the sliajH' of tlio lica<l, luaiKlihlcs, and aiitcniuu' this .sjx'cics 

 approaches ^^ viocsori/l Kniery of I'apujusia, lnit the inan(ni>les are 

 (leci»le<lly shorter and the pilosity and arran^'enient of the sponj,'iforni 

 appenthip's of tlie petioh' are very different. The Hornean speeies 

 is also rehited to four Ja\anese speeies recently described hy Forel 

 (^^ kracpcUni, kotiingshcrgi, sigtuar, nud rhhar), but is smaller than any 

 of them. It can be readily distinguished from /rm/yx//^/ and Ictniinija- 

 hirgi by the \vell-<li'velope<l, spiniforni, preapical tooth of the mandi- 

 bles. N. sigucac possesses a translucent inner border to tiie mandil)les 

 and an emarginate clypeus and in lUmc 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. Strumigexys bry.wti, sp. nov. 



Female. Length, 4.S mm. 



Slender; head fully IJ times as long a.s broad, its posterior border deeply 

 and seniicircularly excised, the sides gradually converging to the rather larpe, 

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

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

 Mandibles fully \ as Ions as the head, straijiht, flattened, with parallel borders, 

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

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

 tooth absent. Ch-peus flattened, as long as broad, its anterior border entire. 

 Antennae verj- 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 mesonotura and scutellum, the epinotum low 

 with short horizontal base and long vertical decli^'ity, 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 decUvitj'. 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. Posti>etiole 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
