The 3rd cuhital cellule in front is twice the length of the 2nd. 

 Abdomen not much longer than the head and thorax united- 

 Body black, pilose. 



The exact systematic position of this genus can only be satis- 

 factorily settled when the, no doubt apterous, female has been 

 discovered. Possibly it may form, the type of a new sub-family, 

 which might be defined by the toothed apex of clypeus, bidentate 

 mandibles, serrate tibiae, longish metathorax, by the basal 2 

 abdominal ventral segments not being separated by the 2nd pro- 

 jecting straight or obliquely downwards, and by the absence of a 

 curved spine on the apex of the abdomen. 



OdontothytDius bidentata, sp. no v. 



Black, densely covered with white pubescence : the lower 

 half of the inner eye orbits narrowly above,— more widely in the 

 centre — face, clypeus, base of mandibles, the base and outer side 

 of the 4 front tibiae, the spurs and tarsi and the base of the hind 

 tibiae, and a broad band on the apex of the pronotum, pale yellow. 

 Front and vertex closely, distinctly, and uniformly punctured, 

 opaque ; the part behind the ocelli more shining and sparsely 

 punctured, densely covered with long white pubescence ; the 

 clypeus with the pubescence longer. Middle of mandibles piceous^ 

 their apex black. Palpi black, the apical joints testaceous. Thorax 

 closely, strongly punctured, opaque, the apex shining, more 

 sparsely punctured. Abdomen opaque, shagreened, the apices of 

 the segments smooth and shining. Hind tai-si tinged with rufous. 

 The 1st recurrent nervure is received shortly, but distinctly 

 behind, the 2nd shortly beyond the middle of the cellule. 

 Antennae opaque, almost bare. The face at the eyes above ends in 

 a short rounded tooth, and there is a less distinct one on the lower 

 side. The wings have a distinct fuscous-violaceous tinge, with 

 black stigma and nervures ; the 3rd cubital cellule is not much 

 wider in front than behind. 



Length 11-12 mm.
