FIGS. 24-25. CYNIPS ECHINUS VARIETIES ON QUERCUS 
DOUGLASII 
Possible extensions of known ranges shown by shading. 
Of speciosa: Holotype and 3 paratype females and galls at the 
Philadelphia Academy; paratype females and galls in the American 
Museum of Natural History, the Museum of Comparative Zoology, the 
U.S. National Museum, the Beutenmiiller collection (?), and the Kinsey 
collection. From Napa City, California, E. H. King collector. 
Type material of both echinus and speciosa, including the holotype 
of the latter, was examined in making the present re-descriptions. 
This gall, found on the blue oak, Quercus Douglasii, is one 
of the most abundant of the cynipid productions in California. 
The young galls appear about the middle of July; in 1922 
Leach failed to find galls at Diablo on July 4, but found young 
galls on July 17. The galls are mature by the first of Sep- 
tember and are then very striking objects, forming deep, coral 
red clusters of spiny spheres on the under surfaces of the 
leaves. The larvae do not mature until later in the fall, trans- 
forming into pupae and adults in November. Emergence 
may occur as early as November 26 (in 1922 at Diablo), but
