 in two specimens, not much wider at base of antennae ; paraf rontals 

 gray pollinose to vertex, sparsely haired outside of frontal rows; 

 median stripe red, narrower than one paraf rontal on entire length; 

 inner and outer verticals developed; orbitals one pair, proclinate; 

 ocellars present; f rontals extending to apex of second antennal seg- 

 ment, the uppermost stronger and reclinate ; face rather strongly re- 

 ceding and concave above the mouth in profile view, not very deep ;
