On Q bicolor in Fla. Gall similar to Philonix nigra above, 7.5-8 mm in dia.

Acraspis lanaeglobuli n. sp.

Host: Quercus bicolor [michauxii?]

Gall - Round or globular galls, slightly attached to the under surface of the leaf: .30 to .35 of an inch in diameter and covered with a fine, dense, grayish pubescence; internally, of a pithy structure, with a large, thin-shelled kernel in the centre.

Described from 8 female bred specimens.

GALL. — As described for the species, up to 8.7 mm. in diameter, averaging a little larger than other varieties except gigas and vorisi; on the leaves of Quercus bicolor.

RANGE. — Eastern Florida (Ashmead; types). The data are insufficient to suggest further extensions of this range.

Nothing is known about this variety beyond the data with the type collection. The insect is distinct, and nigra and gillettei should not be made synonyms of lanaeglobuli as Beutenmuller would have them (1918). Q. bicolor galls which I have from New York (Staten Island) and New Jersey (Broadway) average near the size of the present variety, but until we can study insects from these localities we cannot suggest whether lanaeglobuli occurs thruout the Atlantic Coastal Plain or is confined to an area in Florida. The nearest relatives of lanaeglobuli are the Middle-Western gigas on Q. lyrata and the chestnut oaks, and vorisi on Q, macrocarpa and Q. bicolor.
