 lose; maxillary plate alutaceous, with numerous shallow punctures.

 (4.81-5.40); lateral margin straight to slightly concave on basal two- 

 thirds, with submarginal row of 15 to 18 setigerous punctures; trans- 

 verse impression distinct laterally, obsolete medially, with medially 

 interrupted, irregular row of coarse, close-set punctures; anterior lobe 

 impunctate except for moderate punctures laterally and in subapical 

 band, median subapical impression broad, very shallow; posterior lobe 

 with several coarse punctures anteriorly, these more numerous

 width, 3.30(3.15-3.60) :3.33(3. 14-3.71); disc with few to several 

 widely scattered, coarse, sunken punctures. 



Hemely tron : Clavus and corium shining ; clavus with one submedian

 incomplete) paralleling claval suture, elsewhere, except along radial

Mesopleuron: Lateral area polished, impunctate, with few oblique 

 rugulae. 



Metapleuron : Lateral margin of evaporatorium more or less con- 

 cave; lateral area polished, impunctate.

 greatest diameter there equal to that of anterior tibia; latter with nine 

 or ten stout, flattened, blunt spines arising from blackened elevations
