/>;«a/^.— Head red, finely granulated. Antennae reddish-brown, 

 short and stout, 14-jointed, third joint as long as the first and second 

 together, fourth shorter than the third, the following joints much 

 shorter than the preceding and of equal size. Thorax black, opaque, 

 finely and evenly granulated. All the grooves are narrow and sharply 

 defined. Parapsidal grooves continuous and running obliquely to the 

 scutellum, where they are rather widely separated. Median line fine 

 and continuous. Anterior parallel lines extending to the middle of 

 the thorax. Lateral grooves deep, very long and running parallel 

 with the parapsidal grooves, but not extending to the anterior part of 

 the thorax. Pleurae rugose and somewhat finely aciculated with a 

 small smooth area situated posteriorly. Scutellum coarsely rugose, 

 foveae at base large, deep and fairly well apart. Abdomen smooth 

 shining reddish-brown, slightly pubescent at the extreme base. Legs 

 dark yellowish-brown. Wings hyaline, veins yellowish-brown and 

 semi-translucent ; radial area open, the veins almost touching the 

 costal margin ; cubitus fine and extending to the first cross-vein, 

 areolat large; second cross-vein angulate. Length 2.50-3 mm.

A fine large species with short stout antennae. The 

 thorax is evenly granulated, and all the grooves are fine 

 and distinct. I have taken a number of the flies ovipositing 

 in the buds of white oak {Quercus alba) late in May, but I 

 do not know what the gall is like.
