 tliree stouter and more widely separated than the others; the apical 

 slope is irregularly striated around the edges; the center is finely 

 obscurely stria'ted. Propleurae smooth, irregularly striated down the

 a smooth one. Pygidium strongly deeply punctured, with a smooth

Black, the labrum and the mandibles except for a black mark near 

 the apex in front, red, the base of wings hyaline, the apex from the 

 stigma fuscous violaceous, tbe stiigima black, the nervures blackish 

 brown; the metai;otal area slightly longeT than it is wide at the base, 

 the keels roundly curved,, not mieeting at the apex nor reaching to the 

 tranverse keel, to which they are united by two short straight keids. 

 Head a.nd thorax closely strongly punctured; a smooth space in front 

 of the ocelli and at the apex of the propleurae in the middle, this latter 

 space being narrowed and longitudinally striated. Base of metapleurae 

 closely acieulated, the rest striated, the striae not strong, curved in 

 the centrail part, oblique above and below where they are closer and 

 more regular. There is a straight keel down the middle of the metanotal 

 area which is finely irregularly tranversely striated and acieulated; 

 the sides of the metanotum are coarsely acieulated. Abdomen strongly 

 closaly punctured, the punctiiration be^'oming stronger towards the 

 apex. Pygidium closely strongly longitudinally reticulated, striated to

 oblique, not roundly curved; the first abscissa of the radius is as long 

 as the second. 



The male has the clypeus and !nandil)les white except nt the tiiis, 

 tlu^ pubescence is denser and the puncturation stronger; on the base of 

 the metanotum are two areae which are slightly narrowed towards the

 the first transverse keel to th^ second; the parts ontsi.le it iir? 

 irregularly striated; between the two transverse keels are a number r.f 

 longitudinal ones which a-re closer to each other and more oblique on the
