Fifth report on the noxious and other insects of the State of New York

Figites chinquapin, new species

Arising perpendicularly or obliquely from the upper surface of the leaves of the Chinquapin oak (Quercus chinquapin), like pins inserted therein, little slender club-shaped galls nearly a half inch long, formed of a pale green elliptic head like a minute pod, tapering into a slender dull brown stalk twice as long as the head, the surface thinly clothed with fine short hairs ; producing a small black gall-fly with bright tawny yellow antennae and legs, its length 0.10. These singular little galls are met with in May, one or more growing upon the same leaf. The walls of the little pod at their summit arc exceedingly thin and the fly comes out through around hole which it gnaws near the upper end. It is remarkably large in comparison with the small delicate gall in which it is nurtured.
