and eleventh joints are broadly, but not deeply, curved 

 beneath. Head opaque, the vertex and occiput more 

 shining ; almost impunctate ; the vertex closely 

 punctured above, the lower part closely transversely 

 striated ; between and below the ocelli more strongly 

 obliquely striated ; between the antennae rugosely 

 punctured ; in the middle is a short, narrow, deep, longi- 

 tudinal furrow. Mandibles broadly white at the base, 

 the base on the lower side narrowly black ; the base and 

 apex of the teeth piceous ; the apices of the palpal joints 

 testaceous, the front, face and base of the mandibles thickly 

 covered with short, white hair ; the lower part of the vertex 

 is raised in the middle, the raised part being bordered by 

 a narrow, indistinct furrow. Thorax black, closely 

 rugosely punctured ; the propleurae coarsely rugosely 

 punctured and deeply triangularly incised in the middle 

 above, the base and apex being rounded ; its lower side 

 at the apex white. Mesopleurae closely rugose, running 

 into reticulations in the middle ; the apex bordered by a 

 sharp keel behind; median segment coarsely rugosely 

 punctured, widely and deeply depressed in the middle ; the 

 cenchri are large and white. Median segment coarsely 

 punctured, most strongly on the outer side, the sides of the 

 cleft being almost smooth and they are shining. Meta- 

 pleurse deeply excavated in the middle, narrowed below, 

 where in the middle they are crenulated ; in the middle 

 behind these is a large depression. Legs black ; the base 

 of the tibiae — the hinder pair very broadly especially 

 on the outer side — and the basal joint of the hinder 

 tarsi, white ; the claws and calcaria ferruginous ; the 

 former toothed at the base. Wings clear hyaline ; 

 the first radial cellule short, about one-fourth of the 

 length of the second. The second cubital cellule is 

 longer than the first and more than twice the length
