108 Mr. L. B. Piout on new probably also by parasitic habits. The wide range of the family points to considerable antiquity, though it seems to be absent from Australia. Ashmead (Trans. Ent. Soc. London, p. 235, 1900) assigns Olixon to the Bethylidae, subfamily Embolemina?; but gives no reason for placing it in that position, from which the very different antennae seem to exclude it at once. It is by no means certain that Ashmead had seen specimens. VIII. — New Geometridpe in the Joicey Collection, By Louis B. Prout, F.E.S. [Plate VII.] In working through the Geometridse in the collection of Mr. J. J. Joicey I have already come across several novelties, some of them of great interest, and as there is now sufficient material for a Plate — which Mr. Joicey, with his customary munificence, has provided in further elucidation of the species and forms — we think it desirable to publish them without further delay. As all the types are in his collectioUj it is unnecessary to specify this in each individual case. Subfam. (Enocsbomin^. 1. PlieJlinodes h'lap'icata, sp. n. (PI. VII. fig. 5.) S .—36 mm.
