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

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

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

 lel. 



Sphecodes paraplesius sp. nov.

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

 low. This species and 6". 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 5". hanksii 

 are simple and those of 5". 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. 

 Sphecodes arvensis Patton. 



9 . — Elkhart, Ind., R. J. Weith. This species is closely al- 

 lied to 5". dichrous Sm. 

 Sphecodes illinoensis Robt. 



$ . — Elkhart, Ind., R. J. Weith. A small species with 

 simple mandibles; enclosure on metathorax with parallel 

 ridges. 



Prosopis telepora sp. nov. 



5 . — Length 4 mm. Face marks pale yellow, elliptical ; the upward 

 extensions tapering to a narrow streak along the eye margin; tubercles 

 nearly white, collar and tegulae upspotted ; tibiae in front more or less
