includiii}; tlio perlicel black, three times as long as the scape, subclavate. the joiuts 

 of funicle all longer than thick. Wings hyaline, the tegiilae and veins brown,

 hind femora with a bluish tinge, the trochanters, knees and tarsi, except last

BELONURA Ashm. n. g. 

 (Type B. singHlnris) 



Head transverse, wider than the thorax, the vertex broad, the 

 frons slightly impressed medially, the occipital foraminal depre.ssi<)n 

 acutely margined, the temples full ; ocelli subtriangularly arranged ; 

 eyes large, subovate, bare, or with only faint traces of bristles poste- 

 riorly ; clypeus not separated, anteriorly truncate, and with two 

 minute indentations; mandibles 4-dentate ; antennae 13-jointed, with 

 three ring-joints, the flagellum clavate, gradually incrassated towards 

 tip, the pedicel obconical, scarcely longer than the first joint of 

 funicle ; funicle joints increasing in width, but decreasing in length, 

 the joints 2-6 wider than long. Thorax ovate ; the pronotum with 

 the superior anterior margin acute ; the mesonotum wider than long, 

 with the parapsidal furrows distinct anteriorly to a little behind its 

 middle ; scutellum large, convex, with a delicate or subobsolete 

 transverse grooved line just before its apex ; metathorax long, punc- 

 tate, produced into a subglobose neck at apex, the median and lateral 

 carinse distinct, the metapleural ridges fimbriate, the spiracles ratlier 

 large, oval. The postmarginal vein of anterior wings is a little 

 longer than the marginal, the stigmal very little shorter than the 

 marginal, ending in a moderate sized knob with an uncus. Legs 

 normal, the tibial spurs 1, 1, 1, the hind coxa? fimbriate. Abdomen 

 elongate ovate, longer than the head and thorax united, the eighth 

 or last segment being })roduced into a slender, subcompressed stylus, 

 resembling an ovipositor ; the second segment is large, and, without 

 taking into consideration the long stylus, occupies nearly half of the 

 whole surface ; the third segment is about one-third the length of 

 the second ; the fourth, fifth and sixth iniited are only a little longer 

 than the third, and of these the sixth is slightly the longest, the fifth 

 the shortest ; the seventh is longer than the sixth. Male unknown. 



This new genus is remarkable for the stylu.s-like production of the 

 eighth abdominal segment, which readily distinguish it from Halizoa 

 Forst., IsocyrtiLS Walker, Tric/ioglenes Thomson and Triehomalus 

 Thorns., genera to which it seems most closely allied.
