Brownish-red ; the antenna?, three large marks on the mesonotum ; 

 the scutellar fovea, the middle of the mesopleura?, and the abdomen, 

 black ; the legs reddish-brown, the tint being redder than on the body ; 

 the base of coxae and sometimes the tibia? infuscated ; the mesonotum 

 and mesopleurae thickly haired ; the mesonotum punctured in front. 



Length 3 to 4J mm. 



The gall is smaller than that of longiventris, but is 

 similar in shape, and, like it, is found on the veins 

 on the underside of the leaf. The surface is smooth, 

 glabrous, hard and woody, whitish-yellow, with cheeks 

 usually bright red ; the top as a rule is depressed in 

 the centre. The larval cavity small, the walls being 

 thick. 



Frequently the surface bears a few minute warts ; 

 also the red colour may be entirely absent ; and with 

 age the colour becomes brownish. Over a dozen may 

 be found on a single leaf. 



Found from July onwards ; the flies emerge in 

 October.
