22 BRITISH ICGHNEUMONS. [ Microleples 

MICROLEPTES, Gravenhorst. 
Gr. I. E. i, Suppl. 679. 
Head subglobose ; face protuberant. Antennae incrassate, short and 
simple; scape not cylindrical. Notauli entire to disc of mesonotum ; 
metanotum not rugulose, with strong carinae. Abdomen stout, petiolate, 
black, nitidulous, not scabriculously punctate; basal segment neither 
glabrous nor rugulose ; second segment not carinate; terebra concealed. 
Legs incrassate. Areolet wanting. 
I have attempted to place this genus, which has been neglected since 
first erected. The above characters will distinguish it from all other 
Ichneumonidae.

as broad as eyes, and'testaceous; the exserted labrum and very slender 
palpi stramineous; cheeks strongly buccate and very broad, apically 
margined, subproduced above, and smooth with a few large and scattered 
punctures. Antennae stout, nigrescent and hardly extending beyond 
radices; radicula, scape, pedicellus entirely, and the flagellum basally
