Only the agamic form is known, and it is not dis- 

 tinguishable from A. 4-lineatus. 



The gall is found on the catkins of the sessile oak. 

 It is of the same form as that of A. callidoma, but the 

 peduncle is very short or quite aborted. Spindle- 

 shaped, sometimes of an elongated ovoid form ; slightly 

 pubescent when young, glabrous when mature ; white 

 with pink stripes when fresh, yellowish or brownish 

 when mature ; sometimes the sides bear indistinct 

 keels. The flower branch may be thickened or dis- 

 torted by the galls. They are found also on the leaves, 

 which may be incised where the galls are seated. 



They are found in May, become ripe in June, the 

 imagos appearing in the following spring. 



I have bred Synergus facialis from the galls ; and 

 Mayr, besides this species, 8. albipes, Htg. The para- 

 site is Eurytoma rosse. 



I only know this species from Mugdoch Wood. 



Continental distribution : Germany, Austria.
