 ver}' short and broad, the labrum moderate, broadly rounded at 

 apex ; eyes small and prominent; antennae long, filiform, as long 

 as the head and prothorax, the joints rounded, the tenth slightl}' 

 wider than long, the eleventh longer than the two preceding and 

 a little wider, gradually pointed in apical two-thirds. Prothorax 

 three-fifths wider than long, the sides subparallel and rather 

 strongly, evenly rounded throughout, the edges minuteh' ser-
