100 ANDEIOTJS ALBOPUNCTATA. 



The insects are easily bred if the galls are collected 

 well on in May. 



I know the species only from Mugdoch Wood, near 

 Glasgow. 



Continental distribution : Germany.

Andricus albopunctata, Mayr, Europ. Oyn., 21. 



Similar in size, form, and coloration to A. 4<-lineatus. 



The gall is found in the buds in May and June, but 

 not in those having leaves. It is conical, sometimes 

 with a sharp point at the apex, but more usually 

 rounded there. In colour green, spotted with white ; 

 the surface smooth, shining, unicellular, hard, and 

 woody. It is found in May and June, and falls to the 

 ground very shortly after making its appearance. 

 Length 5 — 6 mm. The colour varies somewhat, some 

 examples being brownish or yellowish-green. 



According to Schlechtendal the fly comes out in 

 November. I have had them in March. 



I have bred both Symrgus radiatus and 8. facialis, 

 from the galls. Brischke gives Torymus rubricipes 

 as a parasite. 



Common. 



Continental distribution : Germany, Austria, France.
