 impressed, the oceii»ut very slightly concave; eyes larjic oval, promi- 

 nent; ocelli small, close toj;ether in a triangle. Antenna' 10-Jointed, 

 Rubtilitbrm, very slightly thickened toward tips, inserted Just above the 

 clypeus, the acapii h)nger than the tirst tlagellar joint. 



Maxillary palpi 4 Jointed. 



Mandibles .{-dentate, nearly equal, the inner tooth a little the smallest. 



Tlunax not much lengthened, much narrowed anteriorly and trun 

 cate posteriorly, the angles of the truncature rounded; the ])ronotum 

 is almost as h)ng as the mesonotum but much narrower, a little wider 

 anteriorly than at base, only about half the width of the very broad 

 head; mesonotum wider than long, with furrows; scutellum semicircu- 

 lar with a transverse furrow all across the- base; metathorax much 

 shorter than high, abruptly truncate.

 the globose abdomen, the relative length of the anterior tarsal joints, 

 and by the vertex of the head not being impressed.
