labrum is notched at the apex. There seems to be no other spe- 

 cies with which confertus can be identified, and I would, there- 

 fore, regard S. falcifer Patton as a synonym of S. confertus 

 Say. 



Sphecodes shawi sp. nov. 



9 . Length 6 mm. Head and thorax black ; abdomen red, the apical 

 segments tinged with black. Face finely and densely punctured, clothed 

 with pale buff-colored pubescence ; clypeus with large dense punctures ; 

 mandibles simple, red, the apices darker. Antennae black, the flagella 

 largely red. The disc of the mesothorax finely and rather sparsely 

 punctured, shining. Wings dusky hyaline, nervures and stigma dull 

 ferruginous ; tegulae partially red ; the second submarginal cell is ex- 

 tremely narrow, the distance between the ist and 2nd tranverse cubital 

 nervures not much exceeding the width of the basal nervure. Legs 

 black, clothed with buff-colored, plumose hairs, the apical tarsi red, 

 exteriorly on the center of each hind tibia there is a long red spot. 

 The enclosure on the disc of the metathorax is not well defined, 

 coarsely reticulated. The abdomen is impunctate except for minute 

 hair punctures. 



One specimen from Hampton, N. H., June 8, 1909, S. A. 

 Shaw. In a part of its characters this species resembles 

 S. pimpinellae which has the second sub-marginal cell very 

 short, but the latter has the mandibles bidentate, the tegulae, 

 tibiae and tarsi red, and is 7 mm. long. The species is dedi- 

 cated to Mr. S. A. Shaw, a most diligent collector of the in- 

 sects of New Hampshire, and whose specimens are more care- 

 fully mounted than any others I have ever had the privilege 

 of examining.
