We have two genera: Whymperia, which is mostly Neotropic but 

 with a single species in southern Arizona, and Baryceros, a rather 

 large genus with most of its species Neotropic and five in our area. 



Key to the Nearctic genera of Baryceratina 



1. Frons with a strong sublateral carina that extends upward from outer margin 

 of antennal socket (fig. 307,a) ; areolet of moderate size, closed (fig. 307,a) ; 



nervellus broken near or above middle 1. Whymperia !(p. 22) 



Frons without a strong sublateral carina (fig. 307.b) ; areolet very small, open 

 (fig. 307,b) ; nervellus broken below middle ... .2. Baryceros (p. 23)

Whymperia Cameron, 1903, Entomologist, vol. 36, p. 122. Type: Whrjmperia 



carinifrons Cameron; monobasic. 

 Protocryptus Schmiedeknecht, 1904, Opuscula ichneumonologica, fasc. 6, p. 414. 



New synonymy. Type: Protocryptus grandis Schmiedeknecht; designated 



by Viereck, 1914. 

 Zamansa Viereck, 1912, Proc. U.S. Nat. Mus., vol. 42, p. 647. Type: Cryptus 



aziecus Cresson; original designation. 



Front wing 8 to 18 mm. long; frons with a basinlike depression just 

 above antennal sockets and a strong vertical carina extending dorsad 

 from outer margin of each antennal socket; setiferous punctures on 

 mesopleurum varying from very fine and dense to moderately small 

 and moderately dense; epomia absent or very faint; upper edge of 

 pronotum simple or with a moderate submarginal swelling; mesoscu- 

 tum rather weakly convex, its notaulus short and weak, or absent; 

 basal carina of propodeum sharp, usually complete, sometimes obso- 

 lescent; apical carina of propodeum sharp, complete or interrupted 

 at middle, often forming a long, obHque, rudimentary sublateral crest; 

 areolet of moderate size, roughly oblong but its front side longer than 

 its hind side, receiving second recurrent vein near its middle; nervulus 

 opposite basal vein; nervellus broken near or above middle; ovipositor 

 cylmdric, the tip of its upper valve with weak transverse ridges. 



Whymperia contains a number of Neotropic species and one in 

 southern Arizona. 



Whymperia tricolor, new species 



Figure 330,a 



Male: Unknown. 



Female: Front wing 11.5 mm. long; general structure and pro- 

 portions as shown in figure 307,a; punctures on thorax moderately 

 coarse, strong, and close. The basin on the frons that is bordered 

 laterally by a carina is both shorter and a little narrower than in 

 other species of the genus.
