Dima, 23 ntl September (A . Koller). 



F^ace and clypeus somewhat strongly punctured, the puncturation 

 on the face interlacing into strise ; the front more weakly and not 

 so closely punctured; the vertex weakly aciculated. Mesonotum 

 closely punctured, more or less finely reticulated, the outer edge 

 more weakly tham the rest. Scutellum more strongly punctured, 

 the apex with a gradually rounded slope; the sides stoutly keeled 

 to shortly beyond the middle. Base of metanotum almost smooth, 

 the rest finely, closely reticulated to the keel; the rest much more 

 coarsely reticulated, the sides transversely striated; the apical 

 slope is much more coarsely transversely striated ahd has a stout 

 curved keel on the top. Upper part of propleuraî finely closely 

 punctured, the rest from shortly above the middle stoutly, longitu- 

 dinally striated. Mesopleurse finely closely punctured, the raised 

 apical part smooth, bordered behind by a stout striated band ; the 

 lower apical part is finely striated. Metapleurae finely, closely 

 striated, the strise stronger at the base below. Basai segment of 

 abdomen shining, the others opaque; there is a narrow white line 

 on the apex of the 2 ni1 segment and the 7 lh is entirely white; there 

 is a distinct oval fovea in the centre of the base of the post-petiole, 

 the sides of which are rather strongly deeply punctured.
