the scape covered with long white hair ; the flagellum almost 

 bare. Head black, strongly and deeply rugosely punctured 

 and rather thickly covered with white hair; the eye-incision 

 and the lower orbits, a small line on the inner orbits above, 

 the sides of the clypeus, a mark above it triangularly nar- 

 rowed on the top, and an interrupted line on the middle of the 

 front, fulvous yellow. Pro- and raesothorax rugosely punc- 

 tured, the median segment more closely and finely punctured ; 

 the base of the pronotum, a large oval inner and a smaller 

 outer mark on the sides of the scutellum, a larger more elon- 

 gate mark opposite the tegulse, a narrow line on the sides of 

 the postscutellum, and a mark on the mesopleurse under the 

 fore wings, fulvous yellow. Legs black, thickly covered with 

 white hair ; the apex of the fore femora, the apical part of 

 the middle and the greater part of the hinder femora yellow 

 above. Wings hyaline ; the radial and the upper part of the 

 cubital cellules to a less extent smoky; the stigma and ner- 

 vures are black; the first transverse cubital nervure is curved, 

 the others are straight, oblique ; the first recurrent is received 

 in the middle, the second in the basal fourth of the cellule. 

 Abdomen shining, smooth ; the base of the third and fourth 

 segments and the greater part of the last three segments above 

 lemon-yellow. The pygidium is keeled down the middle, as 

 is also the basal half of the last ventral segment ; the basal 

 three ventral segments are incised in the middle, the basal 

 not so distinctly as the other two ; in the middle of the 

 second segment is an oval yellow mark ; the third has the 

 sides yellow at the base. 



I place this species in Polochrum rather than in Sapyga 

 because the third cubital cellule is not narrowed at the top 

 and because the antennas are not so distinctly clavate. In 

 the species here described the antennae are scarcely so long as 

 the thorax and the flagellum is not distinctly narrowed at 

 the base.

In Bingham's table (Faun. Brit. Ind., Hym. p. 236) this 

 species comes into " A. Colours black and yellow," " a. Meso- 

 notum striate," and " b^. Comparatively small (16-18 mm.)," 

 which will be now divided : —
