HYMENOPTERA COLLECTED AT BUXA, BHOTAN. 7 



finely than the lateral. Pleurae, except the middle of the pro- and the 

 lower apical half of the mesopleurse, strongly punctured, the metapleurae 

 more closely and strongly than the others. The first abdominal seg- 

 ment shining, smooth, except for a few scattered punctures on the 

 post-petiole ; the others closely punctured, strongly and closely on the 

 second and third, weaker on the others. Disco-cubito nervure broken 

 by a short stump ; the transverse median received distinctly beyond 

 the transverse median ; areolet four-angled ; the nervures meeting in 

 front. 



May be known from G. maculata, Cam., by the bands on the 

 abdomen not being separated, but continuous. The differences 

 between it and C. robusta, Cam. (which has the abdominal bands 

 continuous) may be shown thus : — 



Four front legs rufous, the yellow mark on the lower 

 orbits of equal width, the black apical band on the 

 hind femora half the length of that on the tibiae . robusta. 



Four front legs yellow, the yellow mark on the lower 

 outer orbits much narrowed above, the black apical 

 band on hind femora as long as that on the tibias . cingulata. 



Aca7ithojoppa dudgeonii, sp. nov. 



Ferruginous ; the antennae from the fifteenth joint, the depression 

 at the base of metanotum, posterior median area, and the base of 

 metapleurae black ; the basal part of antennae, the face, orbits, and 

 base of mandibles pale yellow ; the wings yellowish hyaline, the apex 

 from the radius fuscous violaceous, the costa and stigma testaceous, 

 the nervures black. ? . Length, 18 mm. 



Head smooth, sparsely haired ; the front in the middle above finely 

 striated. Mesonotum alutaceous, finely, closely punctured at the apex. 

 Scutellum closely, somewhat strongly punctured, and thickly covered 

 with longish fuscous hair ; the apex above broadly, roundly incised ; 

 the sides smooth, broadly rounded ; the apical slope long, smooth, and 

 bare at the apex. Post-scutellum bordered by a stout, rounded, curved 

 keel ; the base with some striae. Areola large, six-angled, longer than 

 its greatest width, its apex rounded inwardly, the base transverse; the 

 lateral angle is in the middle ; it is stoutly, irregularly, longitudinally 

 reticulated ; the basal lateral area stoutly, irregularly punctured, 

 except round the edges ; the second closely, stoutly, obliquely reticu- 

 lated ; the posterior median area closely, stoutly, transversely striated ; 

 the lateral stoutly reticulated ; the spiracular area stoutly, obliquely 

 striated, the striae more or less twisted. Propleurae closely, finely 

 punctured above, below striated, strongly above, finely below ; in the 

 centre, below the middle, is a stout keel ; the basal upper half of meso- 

 pleuras with large clearly separated punctures, the apical upper half 

 smooth, the lower part closely, coarsely, rugosely punctured; the 

 metapleuraB closely, strongly, rugosely reticulated. Abdomen smooth ; 

 the second and third segments closely punctured, the former more 

 strongly than the latter ; the sheaths of ovipositor largely projecting, 

 as long as the apical two segments united. The long spur of the hind 

 tibise reaches to the middle of metatarsus. The transverse cubital
