 Antennae and legs dark pitchy brown. Head distinctly granulated. 

 Antennse 15-jointed, third joint a little longer than the fourth. Thorax 

 distinctly riigulose. Parapsidal grooves fine and continuous. Anterior 

 parallel lines smooth and shining, not extending to the middle of the 

 thorax. Lateral grooves fine and only indistinctly visible. Pleurse 

 rugulose. Scutellum rugulose Hke the thorax, with two large shining

 apex. It is covered with many short spine-like projections. The surface 

 is also somewhat wrinkled. Light yellowish brown, with some of the 

 spines tipped with pink. Inside it is completely filled with a light brown 

 porous or pulpy substance, and at the base at the place of attachment to 

 the twig are a number of hard oval larval chambers close together, and 

 imbedded in the soft part of the gall. Diameter about 20 mm. Larval 

 chamber 4 mm. long. 



Habitat. — Foot of Yosemite Falls, alt. 4,000 feet, Sierra Nevada, 

 CaUfornia. (Alfred C. Burrill.)
