The author states, "Belongs to the Eriococcini. Larva typically Eriococcine, with rows of dorsal spines. . Adult . . with a pair of plates simulating those of the ; The larva is in all respects of the type usual in the Coccinae (= Lecaniinae) and is entirely without dorsal spines. The anal plates of the adult are very much of the type seen in Ceroplastes, except for the numerous spines on the dorsal surface. In spite of the gall-making habit the genus is indeed possibly close to Ceroplastes. The species described by Ehrhorn as .Cissococcus ? oahuensis has nothing to do with C. fulleri and has quite properly been referred by its author to a new genus. *â ⢠Cissococcus fulleri Ckll. Fig. 19. My single adult specimen is not in sufficiently good condition to permit adding much to the description already given for the genus. The anal plates (Fig. 3C) are rather long, the lateral margin rounded, the tips quite pointed, resembling in this respect the type of plates seen in Ceroplastes. There appear.
