Genus XLIV. Opisthoscelis, Schrader. Trans. Ent. Soc. , vol. i, p. 10, 1862. Rubsaamen, Berliner Ent. Zeit., B. xxxix, p. 214, 1894. Cockerell, Canadian Entomologist, vol. xxxi, p. 276, 1899. This genus was very briefly defined by Schrader when he described his type Opisthoscelis subrotimda : ' Genus Ojnsthoscelis where they have only two long posterior legs. The galls of Opisthoscelis are often found male and foniale under the same leaf. The female gall is in the shape of a pea, but somewhat larger; the male gall very small and conical.' Signoret simply copied his words, and added nothing to the definition of the genus. Rubsaamen gave a general account, but evidently had no fresh material. Cockerell simply says, in his ' Tables for the determination of the genera of Coccidae ' : ' Hind legs only present; these long.' The male and female coccids, like those of the genus Apiomorpha, both produce distinct galls difiering in the sexes; most of these galls are conical, rounded, or spine shaped, and the opening may be on either the upper or the under side of the gall; the adult female, usually fitting close into the wall chamber, sometimes firmlv attached to it. The antennae and the first two pair of legs wanting or aborted; the hind pair very long, the tarsal portion produced into a long hair-like filament, longer than the tibiae, and sometimes curved round over the back. The tip of the anal segment bearing a peg-like tail. These gall-making coccids confine their attention to the foliage of the genus Eucalyptus, and like the members of the genus Apioynorpha, have nob been recorded upon any other plants.
