Pale straw color with obsolete or faint markings. Head bluntly 

 angulate. Smaller and lighter colored than extrusus which it resembles 

 pretty closely. The male pygofers are short and do not extend beyond 

 plates and have only short teeth instead of sityle like appendages. Length

This species is common in North America and Europe but is dis- 

 tinctly a northern form occurring in the northern U. S. and Canada.
