BRITISH ICHNEUMONS. [ Promethus 


PROMETHUS, Thomson. 
Thoms. O. E xiv. (1890), 1475; Promethes et Liopsis, Férst. Verh. pr. Rheinl. 
1868, p. 162. 
Head anteriorly subtriangular, with cheeks not short; face strongly 
nitidulous and quite smooth with epistoma not elevated but with two 
linear impressions above the clypeus, which is often discally foveolate ; 
mandibles slender and discally convex; vertex narrowed posteriorly; ¢ 
face always entirely stramineous, orbits of ? not pale. Antennal scape 
not elongate; flagellum subfiliform, of g nearly always with elevated lines. 
Thorax with notauli more rarely distinct; mesosternum smooth; meta- 
thorax areated, with the petiolar area not broad, and spiracles subcon- 
tiguous with the lateral costae. Scutellum more often black. Abdomen 
with ventral plica pale, and the ? anus distinctly compressed; basal seg- 
ment not short, rarely with abbreviated carinae; second with subcircular 
and not basal thyridii; third with epipleurae inflexed nearly to apex. 
Legs slender, with the tibial calcaria short and claws somewhat elongate ; 
tibiae not banded with colour. Areolet wanting. 
Here again Forster’s name Promethes is inapplicable on account of its 
restriction, and more especially so since no one has hitherto succeeded in 
discovering species that will fall into his zopfszs, which is said to be dis- 
tinguished by having the foveae of the not very broad clypeus no further 
from each other than from the orbits.
