The North American species of Aulacidea and their galls

Aulacidea podagrae (Bassett)

Aulax podagrae BASSETT

Gall. (Plate XXV, Figs. 1-4.) In the pith of the stalks of wild lettuce (Lactuca canadensis). Polythalamous, sometimes causing a swelling of the stalk.

Habitat: Canada; New England and Middle States, south and westward.

The adult is closely allied to A. tumida, but differs from this species by being darker, and by the more evenly wrinkled thorax and more rugulose scutellum. The gall varies from small pits in the pith of the stalk without any traces of swellings externally, to swellings measuring from 10 to 300 mm. in length and from 10 to 60 mm. in diameter.
