Antron pileus, new species

Host: Quercus turbinella

Gall.(Pl 17, fig 19)--A broadly conical bud gall, usually solitary, at end of new growth in summer. Straw yellow above with a purple margin, 4-7 mm in diameter, broader than high, strongly concave below like the pileus of the fungus Coprinus. Larval cavity at very apex and exit hole just below the short nipple.

Habitat.--The type material was sent by Mrs NW Capron, from Prescott AZ, July 12, 1947, and one adult emerged en route. More galls were sent August 1, 1947, and dead adults were cut out of the galls. More were sent in early July 1949, and adults emerged July 10-19. In previous years she had sent galls from Camp Creek, Cherry, Pine, and Young, and I had collected them at Ash Fork and Williams, AZ.
