Cynips (aggregata) finitima, new species
agamic form

GALL.-Moderate in size, up to 25. mm., but averaging nearer 19. mm. in diameter, with a slender, drawn-out, sharply-pointed pedicel at base; light yellow tan to dark russet brown, usually spotted or irregularly striped with dull purple, these markings broader and more conspicuous than in aggregata; often with a whitish or bluish puberulence; occurring singly or (more often) in large clusters; the galls inserted in cracks in the bark of young twigs. Figure 85.

HOST.-Quercus sacame, a close relative of the more northern Q. arizonica.

RANGE.-Chihuahua: Pacheco, 13 NE, 7400', and 20 E, 5400' (types). Possibly wide-spread throughout the Western Sierra in the state of Chihuahua, at least in all but the southernmost hundred miles of that state. Figure 84.

LIFE HISTORY.—Adults: February 4 and later (unrecorded) dates

This insect, from Northern Chihuahua, is very close to aggregata of Southern Arizona and New Mexico. Finitima is generally darker, especially on the sides of the thorax and abdomen, it averages smaller, and—most certain distinction of all—it has a gall which is more conspicuously spotted and covered with purple markings which are broader than those of aggregata.
