 in winter and early spring. 



Kapucinski (1946 : 92-93, 101, 127, pi. 2, figs. 8, 9) recorded Trichomalus laevinu- 

 cha Thomson as a parasite of the larvae of Megastigmus kuntzei Kap. in seeds of 

 Juniperus. Possibly the parasite was misidentified ; at all events, the record needs 

 to be checked.
