 two-thirds as long as one, more slender and twice as long as two, four 

 shorter than three but longer than five, six to nine subequal twice as 

 long as wide, ten slightly longer than nine and pointed. Vertex with few

 smooth, over half as long as mesonotimi, with deep transverse fvirrow 

 across anterior margin and a row of punctures across base. Metanotum 

 half length of scutellum, shining with deep furrow across anterior
