Seutelluin small, Hat, armed with a long slender spine. Epipleura w^th a short tooth beneath tho base of the wing-cover. Aiitenu;c and legs with the usual knobs at end of joints. Wingcovers Hat, very much wider and longer than the abdomen, nearly spindle-shaped in outline, almost membranous and translucent throughout, the costal areole wide, crossed by a coarse diagonal vein, followed by a longer areole which is also bounded at tip by a diagonal vein which sends oil" a thinner vein to curve outward and bound a narrow, cuneus-like areole running to the tip of the wing-cover, behind this, ex tending inwardly, are four long arcoles which constitute the end of tho wing-cover. Abdomen a little swollen at base, narrow behind. Middle coxa; placed far back from the anterior pair, but not remote from the posterior coxa?. P. annulata n. sp.

Head short, subglobose, with the tylus forming a prominent vertical ridge, bounded by swollen cheeks; eyes prominent, brown; rostrum reaching to behind the middle coxie, dark piceous, paler on the middle and beneath.

The cubital area is long, narrow, ob lique at tip, and from it is continued a much narrower apical areolar extension, and these areas are all punctate and minutely bristly along the veins. Abdomen polished, somewhat piceous at base aud tip, tinged with rufo-ferrugiueous on the sides supe riorly, acutely narrowing towards the tip in the male.
