Antenna: inserted in the middle of the face, approximating, long, 

 pubescent, subsetaceous in the males, filiform in the females, 

 composed of numerous joints (never transverse); basal joint the 

 most robust, ovate, truncated obliquely, 2nd as long but slender, 

 3rd very long, 4th much shorter (1), the remainder decreasing 

 in length to the apex, the terminal joint being longer than the 

 foregoing (lb). 



Labrum minute concealed beneath the clypeus, horny, ciliated 

 with long hairs, producing a triangular membranous lobe be- 

 neath (2). 



Mandibles small, robust, subtrigonate, slightly bent, bidentate 

 at the apex (3). 



MaxillcE terminated by a rounded pilose lobe, having a smaller 

 fleshy one on the inside. Palpi long pubescent, 5-jointed, un- 

 equal, 1st and 2nd subclavate, the latter rather longer and more 

 robust, 3rd the longest but slenderer, 4th rather shorter, 5th 

 scarcely longer than the basal joint and very slender (4). 

 Mentuvi oblong dilated anteriorly, the angles truncated and re- 

 ceiving the base of the Palpi, which are 4-jointed, 1st and 2nd 

 joints obtrigonate, especially the latter, 3rd and 4th more slen- 

 der, the former subclavate, the latter subconic. Lip placed far 

 behind the mentum, membranous, hollow, deeply and acutely 

 cleft in the centre (5).

 long ovate, gibbous. Abdomen almost sessile elongated subcylindric, 

 S-jointed, more linear in the male {7); more robust and truncated at 

 the apex in the female (6); Ovipositor exserted ; frequently much 

 longer than the body; the sheath (6a) arising from the superior 

 ^angle is composed of 2 hollow lobes, externally pubescent and shorter 

 than the Oviduct inserted beneath and formed of a rigid acute and 

 hollow process (b) inclosing 2 other more slender rigid filaments (c) 

 with membranous edges, apparently hollow, lanceolate and striated 

 transversely externally at the apex. Wings with the central sub- 

 marginal cell small, trigonate or rhomboidal. Legs, anterior short, 

 posterior pair long. Coxse, posterior very large. T'lh'iad spurred at the
