actually preying upon the Epinotia caterpillars and presum-

proaches closely in general characteristics our Lestodiplosis 
scrophularise, though it appears to be distinct and is char- 
acterized below.

the body, thickly haired, fuscous; 14 segments, the fifth 
with stems having a length three and two and a half times 
their diameters respectively, the terminal segment with a 
stem six times its diameter, the distal enlargement with a 
length four times its diameter and rounded apically. Palpi

haired. Scutellum yellowish, postscutellum reddish yellow. 
Abdomen reddish orange, fuscous basally. Wings hyaline.
