248 ENTOMOLOGICAL NEWS. [June, '<*) 



smooth, and rather widely separated at the scutellum. Anterior paral- 

 lel lines distinct, not quite reaching the middle of the mesonotum. 

 Median groove from the scutellum, short. Lateral grooves very broad, 

 shining and extending well forward. Pleurae rufo-piceous, finely 

 rugose and pubescent. Scutellum, rufo-piceous, rugose, pubescent, 

 forese at base oblique, shining and scarcely separated by a fine carina. 

 Abdomen opaque, piceous, narrowly rufous at the posterior ends of the 

 segments, distinctly longitudinally aciculated. Legs rufous, pubescent, 

 posterior femora and tarsi piceous. Wings hyaline, veins dark brown. 

 Areolet large, triangular. Cubitus rather delicate and scarcely reach- 

 ing the first cross-vein. Length, 2.50 to 3 mm. 



Gall. On the side of a twig of post oak (Quercus minor) in March. 

 Polythalamous. Elongate, irregular, hard and woody swelling, with 

 the base broadly attached to the twig. Covered with a compact mass 

 of white wooly substance, which is sometimes tinged with red or 

 brown. The wool forms a rounded or almost globular mass on one 

 side of the branch. Length, 15 to 20 mm. Diameter, 12 to 20 mm. 

 Height, 10 to 16 mm. 



Habitat: College Station (Glenn W. Herrick), and Aus- 

 tin, Texas (C. Hartman). 



Andricus texanus sp. nov. 



Female. Head, rufous, very finely and minutely rugose, with dis- 

 tinct pale hairs. Antennae, fourteen-jointed, dull rufous basally, dusky 

 terminally. Thorax, dark rufo-piceous or almost entirely piceous. 

 Parapsidal grooves rufous, distinct and converging at the scutellum. 

 Median groove wanting. Anterior parallel lines distinct and extend- 

 ing to the middle of the mesonotum. Lateral grooves wanting. Scutel- 

 lum rufo-piceous, rugoso-punctate, foveae at base rather large and 

 rounded. Abdomen smooth, polished, piceous. Legs yellowish brown, 

 femora and tibiae usually somewhat infuscated, pubescent. Wings 

 hyaline, ciliate, veins brown, cross-veins heavy, cubitus very delicate. 

 Areolet present, distinct. Length, 1.50 to 2 mm. 



Gall. In clusters, closely packed together, on the under side of the 

 leaves of post oak (Quercus minor). Monothalamous. Hard, woody 

 subcylindrical, wedge-shaped or subtriangular, sometimes more or less 

 flattened, pointed basally at the place of attachment to the leaf. Each 

 individual gall is densely covered with short, coarse, whitish, wool- 

 like fibers. They are closely packed together on the leaf and have the 

 appearance of being one large gall, but each gall may be readily separ- 

 ated and detached. When old the fibers turn brown and the galls 

 drop to the ground. 



Habitat: Austin, Texas (C. Hartman), and College Sta- 

 tion, Texas (Glenn W. Herrick).
