teeth of the mandibles black ; the part behind them 

 piceous ; the palpi white. Thorax black ; the pronotum 

 broadly in front, a line on its sides, a broad line over the 

 mesopleurae ; the scutellar keels broadly, a narrow line on 

 the apex of the scutellum, the postscutellum, two oblique 

 lines on the apex of the median segment, not reaching 

 quite to the apex itself, two marks on the apex of the 

 first to fourth abdominal segments and the apical segments 

 entirely, yellowish white. The upper part of the propleurae 

 finely and closely punctured ; mesonotum closely punc- 

 tured ; beyond the middle (but not the apex itself) with 

 the punctures larger and deeper. Scutellum, except in 

 the middle at the base, with large, deep punctures ; the 

 postscutellum smooth ; the median segment with large, 

 deep punctures, which run into reticulations ; the supra- 

 median area is not very clearly defined, if anything, 

 cordiform, raised and aciculated in the centre ; the 

 posterior median area narrow, longer than broad, rounded 

 at the base, open at the apex ; the other arese not 

 defined, but there is a keel on either side of the 

 spiracles and two down the apex in the centre ; the apex 

 is oblique, its middle strongly transversely striolated, the 

 sides more strongly and more obliquely striolated. Meso- 

 pleurae punctured, except in the middle behind ; the base 

 coarsely irregularly striolated ; the apex with short, stout, 

 widely separated keels; the metapleurae strongly irregularly 

 reticulated and punctured, the part over the coxae obliquely 

 striated. The four anterior coxae and trochanters yellow, 

 the femora, tibiae and base of tarsi fulvous, the hinder 

 coxae black, the trochanters fulvous and yellow, the basal 

 half of the femora rufous, the apical black ; the base of 

 the hinder femora and the hinder tarsi, black. Areolet 

 narrowed at the top, the transverse cubital nervures there 

 being almost united ; the recurrent nervure is received
