Cynips vacciniiforiiiis sp. nov. 



Female. — Head very dark brown, microscopically rugose with scat- 

 tered, large deep punctures and densely covered with whitish hairs. 

 Antennae 14-jointed ; 1st joint long of equal width, 2d considerably 

 shorter, 3d very long and slender, 4th and 5th shorter than the 3d, 

 following joints gradually shorter and claviforni. Thorax black, 

 minutely rugose with large pit-like punctures and densely covered 

 with whitish hairs. Collar red on each side. Parapsidal grooves 

 fine, sharp and smooth, widely separated anteriorly converging at 

 the scutellum, where they are fairly well apart. Anterior parallel 

 lines lost in the rugosity of this part of the thorax. Lateral grooves 

 short and fine. Median groove wanting. Pleurae brown, rugose and 

 covered with whitish hairs. Scutellum coarsely rugose, basal foveae 

 not evident, except by slight depressions. Abdomen pitchy brown 

 covered with short whitish hairs which arise from minute punctures ; 

 dorsal region smooth and polished. Legs pitchy brown, hind femora 

 blackish. Coxae dark brown and hairy. Wings hyaline, veins stout 

 and brown ; radial area broad and closed ; second cross-vein angulate ; 

 cubitus faint and continuous ; areolet large but faint ; anal vein broken. 

 Length 4 mm. 



Gall. — In clusters on the midrib of post oak {Quercus minor), 

 Monothalamous and moderately thick walled with a large round larval 

 chamber. Globular and almost like a huckleberry or fruit of hack- 

 berry {Celtis uccidentalis) with a more or less distinct nipple at the 

 apex and long petiole or stem at the base by means of which it is 

 attached to the leaf. Brown when old and probably green when fresh. 

 The outer surface is slightly roughened or almost smooth. Diameter 

 4-7 mm. ; petiole 1-2.50 mm. long. 



Habitat. — Austin, Texas. 



The gall somewhat resembles that of C. dimorphiis, but is 

 larger and more globose. It occurs in clusters like dimor- 

 phus, but the galls are less closely together and not pressed 

 out of shape, each individual gall retains its globose shape. 

 The male is not known.

 slightly darker terminally. Thorax dark pitch brown, reddish-brown 

 along the middle including the parapsidal grooves, distinctly rugose- 

 punctate, with scattered hairs. Parapsidal grooves continuous, broad 

 and deep; they run obliquely backward to the scutellum. Anterior

 ing well forward. Pleurae pitchy brown rugose, pubescent, with a 

 ' irge, smooth, polished area. Abdomen smooth pitchy brown. Legs
