with deep fovea laterally between spiracles and base, spiracles either 

 slightl}^ before or beyond middle. 



The following key will serve to separate the three genera already 

 described and the new genus. 



KEY TO GENERA. 



Clypeus very large, in female beak-like or nose-like protuberant, in male as lopg as 

 wide, evenly convex; malar space long; scutellum flattened, carinate to apex. .1. 



Clypeus not especially large, in female not protuberant, in both sexes much shorter 

 than wide; malar space almost obliterated; scutellum strongly convex, carinate 

 only at base 2. 



1. Spiracles of first tergite before middle, lateral fovea near base; propodeal cariuae 



faint; clypeus in female beak-like basally, deeply excavated apically, in male 



not longer than face nor densely pubescent (fig. 1) Hybophanes. 



Spiracles of first tergite beyond middle, lateral fovea distant from base; propodeal 

 carinae strong; clypeus in female nose-like, not deeply excavated below 

 middle, in male longer than face, strongly convex and densely pubescent 

 (fig. 2) Zagryphus, new genus. 



2. Abdomen subpetiolate, fu-st segment not much longer than second, spiracles 



somewhat before the middle, lateral fovea very near base; tergites densely punc- 

 tate, opaque Neliopisthus. 



Abdomen distinctly petiolate, first segment much longer than second, spiracles behind 

 middle, lateral fovea distant from base; tergites shining, first and second 

 striate Thymaris.

 No species included. 



Oedemopsis Tschek, Verh. Zool.-Bot. Ges. Wieu, vol. 18, 1868, p. 276. 

 Type. — {Oedeviopsis rogenhoferiTsche^)=Hybophanes scabriculus (Gravenhorst).

Hybophanes (Foerster) Schmiedeknecht, Zool. Jahrb., vol. 3, 1888, p. 4.35. 

 Three species. 

 Type. — Tryphon scabriculus Gravenhorst. By designation of Viereck, 1914. 



Campothreptus Davis, Trans. Amer. Ent. Soc, vol. 24, 1897, p. 247. (Not 

 Foerster). 

 Type. — Tryphon ? nasutus Cresson {not Mesoleptus ? nasutus Cresson, as desig- 

 nated by Viereck, 1914). Isogenotj'pic with Rhyncholhyreus Ashmead. 



Zarhynchus Ashmead, Proc. U. S. Nat. Mus., vol. 23, 1900, p. 59. (Not Ober- 

 holzer). 

 Type. — Tryphon ? nasutus Cresson. 



Rhyncholhyreus Ashmead, Can. Ent., vol. 32, 1900, p. 368. New name for Zarhyn- 

 chus Ashmead, preoccupied. 



Oedematopsis Morley, Brit. Ichn., vol. 3, 1908, p. 258 and 268. 



This genus has been described in considerable detail by Tschek,' 

 in which place he corrects some errors of his original description and 

 adds some characters of the male; and also by Schmiedeknecht.^ 



Viereck was in error when he fixed as genotype of Campothreptus 

 Davis, Mesoleptus ? nasutus Cresson. This species was included by 

 name only by Davis, apparently under the mistaken idea that it is
