lower with an incision in the middle, the incision widest below, a 

 broad line filling the eye incision, extending above and below it, 

 below extending to the malar space, where it is united to an oblique 

 mark ; the temples for the greater part, the mark obliquely dilated 

 upwards from the eyes towards the vertex, below obliquely narrowed 

 downwards, a broad band on the upper side of the pronotum, the 

 band gradually dilated towards the apex, a broad irregular mark on 

 the mesopleurae below the tegulae and almost united at the bottom to 

 a longer, narrower one, a short line on the sides of the mesonotum 

 near the tegulae, a longer, broader one in the centre near the end of 

 the parapsidal furrows, the scutellar basal keels broadly, the sides 

 behind them, the scutellum from shortly behind the middle, the 

 post-scutellum, the part on either side of it broadly, the metanotum, 

 the yellow extending on to the pleurae, except on the two furrows on 

 the apex, and an irregular mark on the apex between them ; a broad 

 band — dilated outwardly at the apex laterally and reaching close to 

 the base of the segment — a line on the apex of the second to fifth 

 segments, narrow in the centre, broadly dilated backwards on the 

 sides, and the greater part of the sixth segment, yellow. The yellow 

 on the upper part of the eye incision and on the pronotum is largely 

 suffused with rufous. The fourth segment is rufous except for the 

 yellow lines and for a broad line in the centre of the basal half ; the 

 fifth and sixth are for the greater part rufous ; the ventral surface is 

 rufous, except that the basal three segments are broadly yellow at the 

 apex. Antennae rufous, the scape yellow below. Legs rufous, the 

 greater part of the coxae and about the apical two-thirds of the femora, 

 yellow. Wings hyaline, the base suffused with yellow, the rest with 

 fuscous-violaceous, the nervures black. ? . 



Length 15 mm. 



Head large, as wide as the thorax, deeply, roundly incised behind; 

 the front and vertex closely finely punctured, almost bare ; the 

 clypeus more strongly but not so closely punctured ; its apical part 

 from near the middle depressed, more shining and more strongly 

 punctured than the base; its greatest width is somewhat greater than 

 its greatest length ; the apex is broad, transverse, the extreme apex 

 keeled, and bordered behind by a distinct furrow. Labrum rufous. 

 The yellow on the base of the mandibles runs into rufous at their 

 middle, the upper margin and the teeth are black. Pro- and meso- 

 thorax, with the scutellum closely and strongly punctured, almost 

 bare above, the pleurae and sternum thickly covered with white 

 pubescence, which is longest on the latter. Parapsidal furrows 

 distinct. Scutellum large, slightly higher than the mesonotum, 

 clearly longer than broad, narrowed and rounded at the apex, the
