spiracles beyond the centre ; the hypopygium does not reach the 

 anus nor cover the base of the terebra, although in Lampronota 

 it has distinct indications of such a modification, and in my 

 'Ichneumons of Britain ' I placed that genus in proximity to the 

 ACLEXITIDES ; and the areolet is triangular or oblique and small 

 or wanting, never rhomboidal as in the BAXCHIDES.
