 low markings as follows: Band across lower part of clypeus 

 (widest in middle and obtusely angular above) , transverse

 dish; abdomen with five yellow bands, that on first segment 

 poorly developed, consisting of a median patch and small, almost 

 disconnected, sublateral yellow marks; band on second segment

 known by the polished mesothorax, with strong well-separated 

 punctures in the anterior lateral region.
