 each postero-lateral angle of the head; genae with moderate, sepa-

 foveate, the fovea smaller and less coarse anteriorly ; dorsum clothed 

 with sparse, silvery hairs, anterior half of mesopleura finely and 

 junction of anterior face of pronotum and dorsum of pronotum 

 angulate, the anterior face longitudinally striate; scutellar scale 

 prominent; propleura with large, deep, confluent punctures, clothed 

 with sparse, silvery hairs, anterior half of mesopleura finely and 

 closely punctate, clothed with fine silvery hairs; posterior half of 

 mesopleura with large, shallow, confluent punctures, clothed with 

 sparse, silvery hairs; ventral half of metapleura with large, shal-

 part of the tergite (in the type the dextro-lateral spot is very 

 obscure) ; lateral basal areas of second tergite with shallow, elongate
