The subtribe Thymaridina of the tribe Mesoleptini was originally 

 formed under the name Thymarides by Thomson ^ for the genera 

 Oedemopsis Tschek, TJiymaris Foerster, and NeliofnstMs Thomson. 

 The first of these has since been shown to be synonymous with Hyho- 

 phanes (Foerster) Schmiedeknecht, the genotypes being synony- 

 mous. To these three is now to be added the new genus described 

 below. 



The systematic position of Hyhophanes (Foerster) Schmiedeknecht 

 has been a subject of much disagreement among systematic workers 

 it and its various synonyms having been placed in no less than five 

 tribes, representing three of the Ashmeadian subfamilies. It was 

 originally placed by Foerster ^ in his family Lissonotoidae. 



Tschek,^' redescribing it under the name Oedemopsis, placed it in the 

 Pimplinae. Brischke * synonymized Oedemopsis rogenhoferi Tschek, 

 the genoty]3e of Oedemopsis, with TrypJion scalriculus Gravenhorst 

 and placed it in the Tryphoninae, considering it allied to Eclytus 

 Holmgren, as did also Snellen van Vollenhoven.^ 



Thomson/ referred Oedemopsis along with TJiymaris Foerster 

 and Neliopisihus Thomson to his subtribe Thymarides, tribe 

 Mesoleptina. Davis, ^ considering the Plectiscini as a tribe of the 

 Tryphoninae, placed the synonymous Campotlireptus Davis (not 

 Foerster), based on the North American (TrypJion) HyhopJianes 

 nasutus (Cresson), in that tribe. Ashmead' left HyhopJianes where 

 Foerster placed it, but redescribed it ' (p. 59) in the Pimplini as Zar- 

 yncJius with TrypJion ? nasutus Cresson as type. ZarJiyncJius being pre- 

 occupied he later * proposed the substitute RJiyncJiotJiyreus. Morley,®
