335 PAPERS READ. NOTES ON THE FAMILY BRAGHYSCELID^, WITH DESCRIPTIONS OF NEW SPECIES. Part III. By Walter W. Froggatt, Technological Museum, Sydney. (Plates xvL-xvn.) This Part of my notes consists of the description of a new and very remarkable species of Brachyscelis, received from Cobur, N.S.W., by Mr. J. H. Maiden, to whom I am indebted for the opportunity of adding it to our list of gall-making coccids. The rest of the paper contains descriptions of a number of new coccids all belonging to the genus Opisthoscelis. Wherever the Eucalypts grow these galls are found, and no doubt, when collections are made from all parts of Australia, this group of the Coccidse will be greatly increased. The difficulty has not been to find galls, but to decide which are distinct species, for in some the galls are very variable, and wliere one species attacks several difierent species of Eucalypts they often differ so much that it is only by carefully examining the female coccids that one can define the specific characters. While in the genus Brachyscelis the female and male galls all have the opening at the apex, in the genus Opisthoscelis it may be either at the apex or at the base on the underside of the leaf; all the species (with one exception) described herein have only the long posterior pair of legs, with an immense prolongation of the tarsal joint, but it is not always quite truncate at the tip as in the typical 0. suhrotunda ; the coccid is more elongate, with the tail more rounded, while in the last stage of the female's existence, in several of these she is so solidly attached to the base of the gall that one can only remove
