Superfamily SPHECOIDEA. 



Genus DICRANORHINA Shuckard. 



Syn. : Piagctia Ritsema. 



In the Proceedings of the United States National Museum^ it 

 is erroneously stated that Turner was in error in reinstating 

 Shuckard's name for this genus. The error was on part of the 

 author and he wishes to apologize for the mistake and for criti- 

 cising Mr. Turner. The spelling by Hope was Dlcronorhina^ which 

 was amended to Dicranorrhina., while the spelling by Shuckard was 

 Dicranorhina. 



TACHYSPHEX WASHINGTONI, new epecies. 



This species is related to fenuipuncfus Fox but may be readily 

 separated from that species by the character of the clypeus.

 margin depressed, medianly with a shallow emargination, sublater- 

 all}'' with two obtuse teeth; the anterior portion of the median con- 

 vexity shining, impunctate, the basal portion sculptured like the 

 front ; front opaque, finely rather sparsely punctured ; frontal fovea 

 distinct, complete; intraocellar area convex, parted by a deep fur- 

 row^; postocellar depression angulate posteriorly and with a deep 

 furrow extending almost to the occiput; head behind the ocelli 

 shining, very sparsely punctured; the distance between the eyes at 

 the vertex slightly greater than the length of the second and third
