a mark on tlie edge beliind on the level of the top of 

 the eyes, the antennal tubercles, the sides of the cljpeus, 

 and the mandibles before the teeth yellow. Thorax above 

 rather strongly punctured ; the parapsidal furrows deep, 

 crenulated ; the scutellum flat, closely punctured ; the 

 median segment rather strongly punctured, tlie punctures 

 running into reticulations at the base, where there is a 

 narrow shallow longitudinal furrow. The pro- and meso- 

 pleurae closely punctured, the apex of the former almost 

 striolated ; the metapleurte above reticulated, slightly exca- 

 vated, crenulated. A spot on either side of the base of the 

 mesonotum, two marks on tlie scutellum, one close to 

 the v.ings, the postscutellum and two marks on either side 

 of it, two large marks on the sides of the median segment 

 (somewhat oblique and broadest at the apex), the edge of the 

 pronotum, a large mark on the propleura, a large mark 

 incised at the apex, and a small mark over the middle coxa?, 

 and two marks on the metapleurse, yellow. Abdomen as 

 long as the thorax, shagreened, covered with a close pubes- 

 cence ; the petiole deeply excavated at the base and also at 

 the apex in the middle, shining, black, the apex pale yellow; 

 the other segments marked with pale yellow at the apices. 

 The apex of the petiole beneath and of the second ventral 

 segment yellow, the latter with the yellow dilated in the 

 middle. The fore wings banded with fuscous from base 

 to apex in front, the band broadest near the centre of the 

 cubital cellules; the basal abscissa of the radius is curved 

 and united to the second transverse cubital nervure; the 

 second cubital cellule is longer and narrower than the third ; 

 the first roeuirtnt nervure is received close to the first trans- 

 verse cubital cellule, the second near the apical third of the 

 cellule. 1 he four front trochanters are black, yellow at the 

 apex ; the hinder pair and the base of the hind femora 

 yellow. 



The male is much smaller (only 6 millim. long) ; it has the 

 thorax less strongly punctured ; the yellow marks on the 

 scutellum are united and longer ; the two yellow marks on 

 the median segment are laiger and extend to the extreme 

 base and a))cx, and are not so oblique ; there is no mark on 

 the mcsopleurje ; the stigma is ])aler ; the legs are darker 

 coloured, wanting the rufous tinge ; all the abdominal seg- 

 ments are yellow at the apex, and the mesonotum is not 

 nearly so strongly punctured.
