Dryocosmus quercuspalustris (sexgen)

Amphibolips melanocera (sexgen)

Amphibolips quercusfuliginosa (agamic)

Callirhytis quercifoliae (sexgen)

Amphibolips melanocera Ashm.

Galls.--Greenish brown and yellowish green round, globular galls, issuing from bud axils of Quercus aquatica [nigra]; they vary greatly in size from one-quarter to half an inch in diameter. The outer shell is very thin, and interiorly there is a central kernel held in place by some very thin hair-like filaments.

This species resembles Amphibolips citriformis. The gall, too, is markedly different in shape, although constructed on the same plan as in that species.

Described from eight specimens bred in June.

Cynips quercus fuliginosa n. sp.

Galls on the willow oak--Quercus laurifoliae

Gall.--Brown, mottled, globular galls, .35 inch in diameter, hard, of a fine corky texture with a central kernel.

Andricus quercifoliae

Galls. Succulent, round gall on the leaves of Quercus catesbaei [laevis], with a loose, whitish kernel; constructed in the same manner as Dryophanta aquaticae, but much smaller in size. 

Bred from galls in May. The galls are rare, and the flies difficult to raise.
