In many stiuctaral points tins species is near the mystaceus 

 group, in the form of the second ventral segment, the neuia- 

 tion of the hind wing, the form of the antenna?, the position 

 of the ocelli, the parallel eyes, and the coarse sculpture of the 

 median segment all showing a close approach to that group. 

 In structural points it is very near homonymus, Scliulz 

 (^politus, Bingh., nee Smith), but differs widely in colouring. 



Gorytes matangensis, sp. n. 



5 . Xigra ; pedibus ferrugineis ; segmentis dorsalibus 2-4 flavo- 

 ciliatis ; alls pallide flavo-hyalinis, area radiali late iufumata, 

 venis fuscis, stigmata tegulisque testaceis. 



? . Head broad, finely punctured. Inner margins of the 

 eyes sinuate, not distinctly convergent towards the clypeus. 

 Thorax finely rugose, the suture between the mesonotum and 

 scutellum distinctly foveolate ; sternum with an indistinct 

 longitudinal carina ; mesopleurai longitudinally striated ; 

 postscutellum and basal area of the median segment coarsely 

 lonoitudinally striated, the apical slope of the median seg- 

 ment coarsely reticulate. Abdomen very minutely punctured 

 and pubescent, the fulvous-yellow pubescence forming short 

 cilise at the apex on dorsal segments 2-4. Second ventral 

 segment distinctly angular at the base; pygidial area small 

 and very narrow. Tibiae without spines, fore tarsi very 

 feebly ciliate. Second abscissa of the radius as long as the 

 third, both recurrent nervures received by the second cubital 

 cell, the first at one-third from the base, the second close to 

 the apex. Cubitus of the hind wing originating far beyond 

 the apex of the anal cell. The first transverse cubital 

 nervure is bent near the base, and sends off a short vein 

 which is continued as a scar to the base of the stigma. 



Length 12 mm. 



Uab. Mt. Matang, Sarawak, 1000 feet (G. E. Bryant) ; 

 February. 



This is very near stenopygns, Handl., but in that species 

 the suture at the base of the scutellum is not foveolate, and 

 the clypeus, pronotum,and abdomen are marked with yellow. 



Subfamily Ntssonixx, D. T. 



Genus Nysson, Latr. 



Four species of this genus were included in the collection, 

 but unfortunately only one is represented in both sexes. I 

 give a key to the species described here : —
