Except for its more woody tissue internally, the gall of this species seems quite identical with the gall of Disholcaspis cinerosa (Bassett, 1881, Can. Ent., XIII, p. 110), which is known from Texas only. The adult, though very closely related to cinerosa, is really very distinct and readily distinguished from that species by the key characters I have given at the beginning of the description of this species. I have examined a large series of adults of cinerosa and do not find that it varies toward unicolor.
