132 BRITISH ICHNEUMONS. —— [Labrossyta 

took one in a chalk-pit at Earlham, near Norwich ; but it is certainly a 
rare species, for upon one occasion only have I met it in any numbers. 
This was by sweeping long grass on the edge of a deep ditch on the 
borders of Stanstead Great Wood at 5 p.m. on 14th June, 1900; I took 
half-a-dozen (which strongly resembled both Afhalia lineolata, Lep. and 

Berts clavipes, Linn., with which they occurred) and many more were 
about, but rain began to descend: I have not again met with it.
