 only three specimens, two males and a female, are known, from 

 Grib Skov, Sjæl Sø (Kryger) and Alhndelille near Ringsted; the dates 

 are ^^/^ — ^s- The species has, as said, been bred from Stilpnotia salicis; 

 only one parasite developed in each host larva, and it pupated in the 

 host whicli generally reached to make its cocoon and then burst, so 

 that the parasite pupa became free.
