SEVERAL attempts have been made to rear avian lice in vitro but in most cases they have been maintained for only one generation1, 2. Stenram3, however, seems to have reared a species of the suborder Ischnocera, Columbicola columbae (Linn.) in culture for several generations without difficulty and I report here that a species of the suborder Amblycera has been colonized successfully in vitro. I also report the first definitive evidence of predation by lice, for this species feeds on its own eggs and nymphs.
