I have seen two males of this species from Milwaukee Co., 

 Wisconsin, July 27, 1907. They belong to the Public Museum 

 of Milwaukee and bear the number 25,492. They differ from 

 the type as follows : The middle lobe of the clypeus is not so 

 acute and is broader ; and the scape is entirely yellow. 



$ . Length 6 mm. More robust than the male. Anterior margin 

 produced in the middle into an acute narrow tooth, with a small, dis- 

 tinct, sharp tooth laterally. Distance between the eyes at the clypeus 

 not as great as the width of the clypeus. counting the middle lobe. 

 Space between the antennae distinctly greater than the space between 

 the antennae and the eye margin. Fourth joint of the antennae twice 

 or a little more than twice as long as the third and distinctly longer 

 than the fifth; second and third joints of equal length; antennae simple. 

 Furrow from lower ocellus not very strong. Depressions near lateral 

 ocelli about the same as in R. pcilii-clldtus Pack. Distance bet \vivn the 

 lateral ocelli about the same as that to the nearest eye margin; mvlli in 

 a triangle. A low raised carina in the middle of dorsulum. Head and 

 thorax shining, with rather close fine punctures. Metathorax without 

 a basal enclosure; with a distinct, deep, longitudinal furrow, which 

 broadens on the posterior face ; sides of posterior face bounded by
