HYMENOPTERA OF SARAWAK. 155 



scutellum shagreened ; the apex of the mesopleurse obliquely 

 striated below. Basal area? of metanotum obscurely punctured ; 

 the posterior median area closely transversely, the lateral more 

 strongly and less closely striated ; the sides and apex of the 

 segment thickly covered with longish white pubescence. 



Canojoppa, gen. no v. 



Mandibles very broad, largely projecting below the mouth 

 at the base, their apex with 2 large, widely separated teeth ; 

 below broadly roundly curved from the base to the apex. 

 Occiput roundly incised. Temples broad. Face flat, not sepa- 

 rated from the ciypeus, which slightly projects in the middle 

 at the apex. Scutellum raised; its sides and apex on the top 

 with a distinct keel, its apex with an oblique slope. Median 

 segment completely areolated, its base in the middle broadly, 

 obliquely depressed ; areola clearly separated from the base of 

 the segment, broad behind, roundly narrowed at the apex ; the 

 sides of the segment with, short, sharply pointed teeth. Meso- 

 sternum with a curved furrow on the sides at the base. Areolet 

 obliqup, large, 5-angled ; the disco-cubital nervure broken by 

 the stump of a nervure. Legs long, slender ; the basal 2 joints 

 of the hinder tarsi as long as the tibia?. Antenna? longer than 

 the body, stout. Post-petiole broad, obliquely sloped at base 

 and apex; 2nd and 3rd segments minutely closely punctured, 

 not striated ; there are 7 segments ; the last is longer than the 

 Oth. Head cubital, as long as wide. 



I am only acquainted with the $ of this genus. Character- 

 istic is the form of the mandibles, which are larger and stouter 

 than usual, the longer hinder tarsi and (for the Joppini) the 

 regularly areolated metanotum. 



denojoppa longitarsis, sp. nov. 



Black, shining ; the face, ciypeus, the outer orbits broadly, 

 the inner more narrowly to near the top, a line on the apical 

 half of the pronotum, broader line on the lower edge of the 

 propleura?, a broader one on the lower part of the mesopleura 3 . 

 the tubercles, a broad mark, longer than wide, on the apical half 

 of the metapleura?, touching and below the keel ; a mark, longer
