beyond the posterior margin by about one-fourth of its length in the 

 £ minor, and by about one- seventh in the $ major. Close to the 

 base it has a transversely-placed projection or tooth . . . ; the scape 

 is widely curved beyond the level of the projection. Flagellum without 

 a distinct club, all the joints subequal in length, the first about three 

 times longer than wide. Pro-mesonotum evenly arched. The long 

 and slender mesonotum is almost cylindrically narrowed. Epinotum 

 almost cuboid, the dorsum horizontal, nearly twice as long as wide, 

 the declivity almost vertical ; between them are two broad flat teeth, 

 or two sharp and nearly dentiform angles, the space between the 

 angles excavated. First node wedge-shaped, with a broad peduncle 

 in front, as high as thick at the base, emarginate above, and with a 

 longitudinal impression behind. Second node also narrowed above. 

 Legs very long, thin and slender. Head, pronotum and petiole feebly 

 shining, in the £ minor closely, finely and rather irregularly reticulate, 

 in the $ major fairly coarsely striate in addition ; mesonotum and 

 epinotum (including the declivity) coarsely and transversely rugose or 

 striate, the sides longitudinally striate below. Abdomen shining, 

 shallowly and finely coriaceous. Pilosity sparse, reddish and short. 

 Legs and antennae with decumbent, or sometimes oblique, long hairs. 

 A fringe of long red hairs on the anterior margin of the clypeus and 

 some not very long ammochaetae under the head. More or less dark 

 brown or brownish-black ; mandible and tarsi yellowish to reddish, 

 nagellum and legs brownish-yellow to reddish-brown. 



" 9 . 10 - 3-13 mm. Thorax almost as wide as the head. Disc of 

 mesonotum smooth, with sparse, piligerous punctures ; the rest 

 of the thorax coarsely and unevenly rugose. The epinotum with very 

 feeble and broad tubercles. Wings fairly long, almost vitreous 

 (slightly tinged with yellow), costa and nervures brown. Otherwise 

 just like the £ major but often with a more brightly coloured head. 

 The tooth on the scape of the antenna a little smaller. Legs often 

 quite red. 



" $ . 8 - 5 mm. The tooth on the scape very distinct. Mandibles 

 with 7 or 8 teeth. Head longer than wide, with a very 

 distinctly, feebly convex hind margin. Second joint of the flagellum 

 longer than the first. The epinotum forms a complete oblique plane, 

 hardly convex. Head reticulate-punctate, almost dull. Thorax 

 irregularly and fairly coarsely rugose, shining. Otherwise like the 

 5 minor. Black ; legs, base of the mandibles, antennae, apical 

 margins of the abdominal segments and the pilosity brown ; apical 

 half of the mandibles reddish.
