. The Canadian entomologist. Entomology. 238 THE CANADIAN IvNTOMOLOGIST NEW SPIDERS FROM CAXADA AXD THE ADJOINING STATES, No. 3. BY J. H. EMERTON, Boston, Mass. Since the second paper of this series was pubhshed in 1919 many Canadian spiders have passed through the writer's hands, among which several species appear to be undescribed, but have waited for pubHcation in the hope that more specimens of the same kinds might be found. The new Grammonota from the southern end of James Bay is represented only by one of each sex, though it is probably abundant like other species of the genus. Three other species are known by only one male each. The three Cyhacus have long been described and named, but much new material makes it easier to distinguish the species and so new descriptions and figures have been Fig. 1.—a. Mctapobactnis pacificus, side of cephalothorax; b. top of head showing short horn; c, tibiae of male palpi; d, under side of palpal organ. Metapobactrus pacificus 11. sp. Cephalotliorax i mm. long. Color light yellow without any markings on cephalothorax or legs. The cephalothorax has the head slightly raised and with a short, pointed horn directed forward between the upper eyes, which are twice as far apart as they are from the lateral eyes. The front row of eyes is shorter than the upper row and has the lateral pair larger and the middle pair smaller than the eyes of the upper row. ( Fig. i. a, b.) The sternum is as wide as long and extends backward between the posterior coxae, which are their diameter apart. The abdomen is broken off and lost. The male palpus has the tibia a little longer than wide with a short, dark process at the outer corner and a smaller lutcolored one on the inner corner. (F'ig. i c.) This differs from the tarsus in Coniicitlaria. which genus is suggested by the process on the head. The palpal organ has a long tube, which coils over the tmder side of the palpal organ in one and a half turns. (Fig. i. d. ) " One male (jnly.
