synonymous with TrypJion ? nasutus, the species he had before him. 

 The type of Carn/potlirfptus Davis is therefore Tryphon ? nasutus 

 Cresson. 



The only North American species that has been described is Hyho- 

 phanes nasutus (Cresson), redescribed in more detail by Davis.

 Plectisddea (Campoihrepius) nasuta (Cresson) Viereck, Hym. Conn., 1917, p. 276. 



This species differs in some respects from Schmiedeknecht's de- 

 scription of the genus, as follows: Antennae distinctly shorter than 

 the body; eyes in female slightly convergent below, 

 in male parallel: second and third tergites nearly 

 quadrate, not or barely longer than wide: fourth 

 tergite as well as the first three distincth' though more 

 weakly sculptured. 



The male has not been heretofore described. It 

 differs from the female principally in having the 

 clypeus flattened medially and broadly rounded

ZAGRYPHUS, new genus. 



Differs from IlyhopJianes (Foerster) Schmiedeknecht principally as 

 follows: Head not wider than thorax; clypeus nearly twice as long 

 as face, in female nose-like protuberant, weakly impressed below, 

 shining with sparse setigerous punctures, face elevated in middle to 

 level of clypeus; clypeus in male strongly convex, densely punctate, 

 and, together with the medially protuberant face, sides of frons and 

 vertex and posterior orbits, densely griseo-pubescent; antennae of 

 both sexes broadly white annulate; thorax rather densely punctate 

 and pubescent, notauli vreak; propodeum with sharp carinae, basal 

 areas polished, nearly impunctate, pleural areas densely punctate, 

 median and apical areas transversely rugose; basal joint of hind tar- 

 sus longer than remaining joints combined; nervellus an tef ureal;
