shagreened; young galls light yellow with a rose tinge; older galls be- 
coming light russet brown, unspotted; the outer shell rather thin but 
hard and brittle when dry. Internally filled with silky, moderately 
dense (but not packed), branching fibers which hold the larval cell cen- 
trally; some short, incomplete fibers also on the inner wall of the outer 
shell and on the larval cell; the cell up to 3.5 mm. in diameter. At- 
tached by a fine point at the bottom of the drawn-out base; on the upper 
or ('more often) the under surfaces of leaves of Quercus breviloba and 
its form laceyi. Figures 260-261.

RANGE. — Texas: Austin (type, Weld coll.; also Patterson in Kin- 
sey coll.). Round Rock and Leander (Kinsey coll.). Boerne and Kerr- 
ville (acc. Weld 1926). 
, Probably restricted to a limited area in Texas, extending mostly 
west from Austin. Figure 46. 
TYPES.— Holotype and 2 paratype females and galls at the U.S. 
National Museum, Cat. No. 27189. Paratype females in the American 
Museum of Natural History, the Field Museum, Stanford University, 
and the Kinsey collection. From near Austin, Texas; galls October, 
1917; Q. breviloba; Weld collector. 
The present re-descriptions are made from all the types in the 
American, Field, and National Museums and in the Kinsey collection, 
as well as from a large series I have from near the type locality. 
This gall closely resembles the galls of the related species 
bella and dugesi, but differs in having a drawn-out, blunt base. 
Patterson found young galls as early as June 7 (in 1921).
