Hampton, N. H., Sept. 9, 1909, S. A. Shaw. This species 

 is allied to S. Icvis, but differs in the hyaline wings and the 

 sculpturing of the metathorax ; in S. levis the ridges are paral- 

 lel.

Kingston, R. I., June 10, received from Professor John Bar- 

 low. This species and S. banksii are the two smallest species 

 of Sphecodes known to me. The resemblance between them 

 is so close that I should be inclined to refer them to the same 

 species were it not for the fact that the mandibles of S. banksii 

 are simple and those of S. paraplesius are distinctly bidentate, 

 which according to some taxonomists would place them in 

 different genera. In an attempt to segregate the genus Sphe- 

 codes into a number of minor genera, the dentition of the man- 

 dibles has been employed as a generic character ; but it does 

 not appear well adapted for this purpose since it would separ- 

 ate species apparently very closely allied.
