Hairs on the legs longer than in vcslalis. Hind metatarsi slightly shorter than in vestalis. The best characters for distinguishing distiiictiis from vt-stalis lie in the male antennae. These are much shorter than in vestalis—length of flagellum 5 mm.—and have the 3rd joint about as long as the 5th, the 5th being much shorter than the 3rd and 4th together. Armature like that of vestalis ; but there arc ilifferenccs in the relative dimensions of the parts, and the inner margins of the forceps arc less hairy, especial!}- towards the base. I took Ps. disliiulus pleiuifully at Colinton, near I II 3i.
