ANDRICUS AESTIVALIS. 



107 



The flies appear at the beginning of July. It 

 is not known if they have an agamic generation. 

 From the experience of Giraud the <$ must be very 

 rare, for among 200 examples he only found four 

 males. 



Mayr records Torymus regius, and Giraud Elachestus 

 gallicolus, Gir., as parasites, and the latter gives his 

 Aulax pinnatus as an inquiline.

I introduce this species on the authority of a ? 

 which I captured at Loch Lomond, and which agrees 

 very well with a type I had from Prof. Mayr. If not 

 aestivalis, it is certainly different from any of our other 

 British species.

 spring form of this species, but Beyerinck (Beob. ii.
