Thorax more coarsely and strongly sculptured than in typical 

 assectator and often somewhat more shining. The mesoscutum is 

 scabrously mat, with some wTinkling and often with more or less 

 distinct hregular punctures. The mesoscutal sculpture varies from 

 almost like that of typical assectator to rather strongly wrinlded and 

 punctate in some individuals from the Upper Austral Zone. Speci- 

 mens appear to average a trifle smaller and more slender than do those 

 of typical assectator. 



Coloration like that described as typical for the species, or with 

 the sides of the thorax more or less dull ferruginous.
