 Black, with rather abundant dull white hair, faintly 

 creamy-tinted on head and thorax, dark fuscous on face 

 below antennae (but pale about mouth), rather narrowly 

 fuscous also at sides of front, and some fuscous hair on 

 thoracic dorsum ; fifth abdominal segment at apex, and 

 sixth segment also^ with dark fuscous hair, some black hair 

 on middle of fourth segment^ but the abdomen otherwise

 but broad^ the facial quadrangle much broader than long ; 

 mandibles and cheeks ordinary ; process of labrum broadly 

 truncate ; antennae long, ordinary, black, third joint a little 

 longer than fourth ; clypeus irregularly rugosely punctured, 

 shining between the punctures ; malar space about twice as 

 broad as long; front and vertex coarsely rugoso-punctate, 

 a small triangular depression in front of middle ocellus ; 

 mesothorax brilliantly shining, with strong and large but 

 well separated punctures ; scutellum more densely and very 

 irregularly punctured ; metathorax very coarsely sculptured,
