triangularly narrowed to the apex), a line on the top of 

 the metapleurc-E at the base and a large mark on the top 

 near the apex (transverse above, roundly narrowed below), 

 yellow. Parapsidal furrows distinct, the middle lobe 

 distinctly raised above and separated from the lateral ; 

 the three lobes bearing rather deep, distinctly separated 

 punctures ; the sides smooth ; the scutellum and post- 

 scutellum smooth. Median segment closely and strongly 

 punctured ; the punctures behind the keel more widely 

 separated, the apex in the middle transversely striated ; 

 there are no teeth ; the yellow part is distinctly bordered, 

 ■especially the apical part, and the segment is covered 

 with long fuscous hair. Pro- and mesopleur^e strongly 

 punctured, except the former at the base and the latter at 

 the apex ; metapleura^, if anything, more strongly 

 punctured, except on the yellow part at the base above. 

 Mesosternum closely punctured ; the furrow becomes 

 much and triangularly widened at the apex. The four 

 anterior legs are pale fulvous, the coxae and trochanters 

 pallid-yellow ; the hinder pair are of a deeper fulvous ; 

 the coxae are black, yellow in the middle behind ; the 

 apical joint of the trochanters and the knees black ; the 

 apex of the tarsi and of the tibiae fuscous. Wings hyaline, 

 iridescent ; the space between the base of the stigma and 

 the transverse basal nervure, pale ; the areolet very 

 narrow, the transverse cubital nervures pale in the middle ; 

 the recurrent nervure is received almost in the centre of 

 the areolet ; the transverse basal nervure is interstitial. 

 Abdomen black ; the base of the petiole broadly, its apex 

 more narrowly, the base of the second segment, its apex 

 more narrowly and the apices of the other segments, 

 yellow ; the petiole is smooth and shining, tuberculated 

 at the base of the dilated part, its middle with an oval 

 fovea. The second and following segments are closely
