of ridges describing large foveae, ridges on sides converging to form 
a small, spinose projection. Legs simple, not spinose; claws appar- 
ently simple. Fore wing as figured. Metasoma robust on basal four 
segments, terminal segments forming a tube very much as in Hypo- 
cleptes. Body without noticeable setae and without strong surface 
sculpturing except for propodeum. 
Type-species. — Protamisega khatanga , new species. 
Remarks. — This genus differs from the preceding in having the 
wing venation less simplified and in having the scape longer and in- 
serted lower on the head. In the last feature it resembles Procleptes 
of Canadian amber (Evans, 1969), but the latter has stronger pro- 
cesses on the propodeum and much more obvious surface sculpturing. 
Protamisega khatanga, new species 
Length 1.9 mm; fore wing 1.2 mm. Body dark brown, scape and 
basal parts of legs also fuscous, but appendages fading to lighter 
brown apically; wings hyaline, veins and stigma light brown. An- 
tennae prominent, middle segments about as wide as long. Segments 
of hind tarsus in the following ratio: 17:6:6:5:9. First four meta- 
somal tergites in approximately the following ratio, measured from 
the side: 13:13:8:4. The terminal tubular portion appears to be 
made up of three segments, although the details are obscure. 
Holotype. — Taimyr, N. Siberia, 1970, amber specimen no. 
3130-19. 
Discussion 
Ten additional pieces of amber from the same source contain un- 
identifiable specimens, all of which I would judge to be Bethyloidea; 
some of these probably represent additional specimens of species 
described above. The preponderance of Bethyloidea in this material 
doubtless reflects the fact that many are associated with trees and are 
small enough to be preserved in small pieces of amber, as mentioned 
earlier. Nevertheless it is difficult to escape the impression that 
Cleptidae, at least, were much more abundant than they are today, 
for the family is now represented by only a few genera containing 
species that are only rarely encountered. Since the Cretaceous 
Cleptidae have the general habitus of contemporary forms, it is per- 
haps a safe assumption that they, too, attacked Symphyta and Phas- 
mida, groups that may well have been more important parts of the 
fauna in the Cretaceous than they are today.
