Bassinj. 

 Sussaha, gen. nov. 



- 9 Antennae 22-jointed, the last joint twice the length of the preceding, win</s 

 without an areloet ; transverse median nervure in forewings interstitial ; in 

 the hind wings it is broken almost in the middle. Clypeus separated from 

 the face, its apical two-thirds depressed, the apex transverse. Scutelluni 

 roundly convex, the sides keeled to the middle. Metanotum with 2 stout 

 curved keels in the centre of the base. Basal segment of abdomen sessile, 

 longer than the 2nd, its spiracles prominent, the 2nd segment with thyridia : 

 ovipositor prominent, broad. 



The abdominal spiracles are placed well behind the middle ; the sides 

 beyond them are bordered by a keel ; the 2nd segment has no keels ; the 2nd 

 segment is clearly longer than wide. The mandibles have their teeth below 

 united by a membrane, the projecting apical parts of the teeth thus being- 

 short. Face and clypeus almost bare, not curved with silvery pubescence. 

 The malar space is nearly as long as the antennal scape. Occiput and 

 cheeks margined. Middle tibial with 2 spurs ; the i^rd joint of the tibial 

 is slightly longer than the last ; the long spur of bind tibial one-third of 

 the length of metatarsus. 



This genus looks very like a Bassus. In the arrangement of Dr. Ashmead 

 it would come in near Syntactus and Calliplirusus. 

 Sussaha hicarinata, sp. nov. 



Black, the base of mandibles, palpi, tegulae and a spot on apex of pronotum 

 and a very narrow line on its base, yellow; the gastrocoeli, the apex of the 2nd 

 and the base of the 3rd abdominal segments narrowly rufous. Legs black, 

 the fore legs almost entirely, the middle femora above, and the 4 hinder 

 tibial below, testaceous, the calcaria pale testaceous. Wings hyaline, the 

 nervures and stigma black. 

 Length 5 mm. 

 September. 



Head smooth and shining ; the clypeus clearly separated, the lower part 

 depressed, obscurely longitudmally striated. Mesonotum closely, strongly 

 punctured. Scutellum roundly convex, the sides of the base keeled. Meta- 

 notum at the base irregularly rugose ; its centre with 2 keels which diverge 

 roundly at the apex ; the apical slope closely, rugosely transversely striated. 

 Pleurae smooth, the lower part of the pro-and metapleurcc striated. Median 

 segment thickly covered with white pubescence. First abdominal segment 

 somewhat strongly longitudinally striated, the strial interlacing ; the basal 

 half of the 2nd finely, closely regularly striated ; the other segments are 

 smooth ; the sheath of the ovipositor is longish. 

 Bassus indicus, sp. nov. 



Black, the face, clypeus, a broad line on the lower part of the inner orbits, 

 mandibles except at the apex, palpi, a large mark on the sides of the 

 mesonotum commencing at the tegulae narrowest at the apex, dilated
