teguliu. ^Icsunotiun closely iiw\ rather stroui^ly punctured 

 throughout, its bajjc in t!ie niiiMle transverse ; the middle 

 raifed, the raised part becoming narrowed and less distinct 

 towards the apex. IScutellum narrowed and de[)re3sed towards 

 the apex, more strongly punctured than the mesonotum, and 

 with the |)unetures more widely separated ; its sides stoutly 

 keeled ; the dejiressiou at its base large, deep, smooth ; the 

 sides at the base slightly obli([ue. Postscutellum coarsely 

 longitudinally striolated. Median segment closely, uniformly, 

 but not very strongly rugoscly ]mnctured ; the area? rather 

 irregular ; the supramedian elongate, wide, obliquely narrowed 

 at the base ; the aj)ical part coftiii-shaped, the apex narrowed ; 

 the outer area3 large, the basal the larger and transverse at 

 the apex ; the apex of the segment has a slightly oblique 

 slope. Propleurai closely punctured, the lower part at the 

 apex strongly longitudinally striolated. The upper part of 

 the mesopleuraj punctured at the base, the upper part under 

 the wings smooth, forming in the centre a stout longitudinal 

 keel ; the lower part stoutly perpendicularly striated, the stride 

 posteriorly becoming curved ; the apex crenulated. The 

 meta])leuriB closely rugosely punctured. The mesosternuni 

 is flat, closely punctured, furrowed down the side, the apex in 

 the middle triangularly depressed. Legs covered with short 

 white })ubescence, the four anterior entirely, the hinder coxae, 

 trochanters and extreme base of the femora red, the hinder

 closely pilose, as long as, if not longer than, the last segment. 

 Petiole narrowed at the base, dilated at the apex ; the extreme 

 base rufous to near the apex, marked with scattered punc- 

 tures; the apical part raised in the middle; the middle of 

 the raised part finely reticulated, the apex with largish punc- 

 tures; the sides above at the ajjcx broadly depressed, irregu- 

 larly striated; outside this depression it is marked with some 

 large distinctly separated jjunctures ; the other segments
