narrow, fuscous stigma; two basal cells; marginal cell open, but the radial 

 vein is very long, four or five times as long as the short basal vein; veins, 

 except the costal, pale.

iiist. 



This is a very typical bethylid and is perhaps better referred to 

 Mesitius than to Epyris. As however, Kieffer believes that the 

 American recent species of Mesitius which this approaches in the short 

 basal and long radial veins are not generically distinct from Epyris, 

 1 have placed it here. The scutellar fovea, which is the only character 

 to distinguish the two genera as restricted by Ashmead does not show, 

 and Kieffer restricts Mesitius to a group of species with the lateral 

 angles of the metathorax produced, to which the present form certainly 

 does not belong. 



CERAPHRONIDAE. 



A single species belonging to Ceraphron is recorded by Burmeister 

 ('31) as occurring in Baltic Amber. 



PROCTOTRYPIDAE. 



This group as here restricted is for the first time recorded in the 

 fossil state.
