Discussion: Winterschmidtia hamadryas (Vitzthum) was found in 

 the passageways of Eccoptogaster rugulosus Ratz. in Prunus insititia, 

 Germany. W. crassisetosa Willmann was taken from larvae and pupae 

 of a scolytid, Phloeotribus scarabaeoides, Italy. This suggests that re- 

 lated species and genera should be found in bark beetle tunnels. To 

 date very little has been done on the study of mites in such habitats.
