creamy white, which is narrow in the micldie, but abruptly 

 enlarged, forming quadrate patches, at the sides ; the lateral 

 creamj-wliite face-marks are not far from equilateral triangles; 

 no supraclypeal or dog-ear marks ; labrum with a transverse 

 white patch ; mandibles dark ; thorax quite hairy ; meso- 

 thorax shiny, but strongly punctured except a posterior 

 smooth area ; base of metathorax smooth and shining, with a 

 large median pit, made double by a longitudinal transverse 

 ridge ; tegulre dark brown in front, pale brown behind ; wings 

 perfectly clear, nervures and stigma dark brown, stigma very 

 little developed; marginal cell obliquely truncate; second 

 submarginal narrowed about one half to marginal, and re- 

 ceiving the recurrent nervures at about the end of the first and 

 beginning of the last fifths ; legs black, even to the tarsi, with 

 pale pubescence ; middle femora curiously flattened and 

 broadened, the lower knife-like edge having a very short 

 brush of orange-fulvous hairs ; basal joint of middle tarsi also 

 flat and broad ; abdomen strongly but not densely punctured, 

 with the usual thin hair-bands ; hair at apex pale. 



(J. — About 7 millim. long. Face more hairy; white 

 markings more conspicuous ; clypeus creamy white, with a 

 black mark on each side of its liind margin ; lateral face- 

 marks rather more produced along the orbital margin than in 

 the female; basal part of mandibles mostly white; anterior

Black with grey and white pubescence. Head transversely 

 suboval ; eyes prominent, in life yellowish green ; face and 

 cheeks with fairly abundant white hair, not dense enough to 

 hide the surface"; face-markings pale yellow, includmg the 

 clypeus, lateral marks, supraclypeal mark, dog-ear marks, 

 labrum, and mandibles except their reddish tips ; the face 

 would be all yellow below the level of the antennw, except 

 the rather obscure clypeal dots, but for the fact that below 

 each dog-ear mark is a small triangle of black, bounded by 

 the clypeus, lateral mark, and dog-ear mark ; lateral marks 

 rapidly narrowing from the upper margin of the dog-ear 

 marks to an acute point on the orbital margin less than the 

 length of the scape above the level of the antennal sockets ;
