The description of the new genus and species of coccid which is given below has been prepared at the request of Dr. Sally Hughes-Schrader, Bryn Mawr College, in order that the tech-nical name might be available for reference purposes in connec-tion with the very interesting cytological studies which she is conducting on various species of monophlebine coccids. The genus is of particular interest because its type and only included species possesses in the adult female stage certain structural characters which suggest relationship with the tribe Llaveiini, although the sum total of its characters appears to place it without question in the tribe Iceryini. Echinicerya, new genus. In the adult female of the genotype there are present those derm struc-tures which the writer has designated as spines in his recent classification of the genera related to this genus. 1 On this account the writer's key to the tribes of Monophlebinae (ref. cit. p. 119) must be modified in such fashion as to leave the segregation of portions of the tribes Monophlebini and Llaveiini dependent entirely upon the number of pairs of abdominal spiracles present. No modification of the larval key to the tribes of Monophlebinae (ref. cit. p. 120) appears to be necessary, as no definitely developed spines have been observed in the first stage larva of this new species. The differentiation of the adult males as given on the same page likewise apparently remains satisfactory as regards this new species. The important characters which differentiate this genus from other genera in the tribe Iceryini, following the writer's keys (ref. cit. pp. 196-197), are, in the adult female, the apparently one-segmented short conical beak, three pairs of abdominal spiracles, presence of distinct spines on the derm, and the presence of numerous (about 20) iU.
