enlarged towards apex, beset with small spines, second joint flat- 

 tened ovate, beset with sense organs and small spines, arista at 

 apex; no carinae on genae below antennae. Pronotum as long as 

 vertex, tricarinate, with a puncture in each half of disk, lateral carinae 

 diverging, following curvature of hind margin of eye; scutellum 

 5-carinate. First joint of hind tarsus longer than the following two 

 together, tibia with one basal, one sub-basal, one sub-apical and three 

 apical spines, tibial spur a little more than half the length of first 

 tarsal joint, awl-shape. Tegmina as in vielanesia, but the neuration 

 obscured by irregular granulation. 



This genus is near MeJaiicftia, but the shape of face and antennae 

 easily separate it. 



(1) P. hrunnea sp. nov. ( 9 ) 



Brown; face with small light dots along keels, a yellowish mark 

 dividing face from the dark brown clypeus, antennae with three dark 

 rings, legs banded yellow and brown. Tegmina brown with a few 

 lighter spots, thickly studded with light-colored granules, mostly 

 along each side of veins, but irregular; wings brownish, dark-veined. 

 Anal style small, spatulate; ovipositor reaching to end of anal style. 



Length 3.5 mm. ; teginen 3.8 mm.

Perimeceoer gen. nov. 

 Type giffardi. 



Head in profile rounded at junction of vertex and face, extending 

 slightly beyond eyes; clypeus continuous with face, not angular. Eyes 

 transverse, antennal emargination on lower edge, extending half 

 across eye; antennae very long, first joint small, claviform, second 

 joint more than four times the length of first, cylindrical, beset with 

 spines and sense organs, apex truncate, arista as long as second joint, 

 arising from apex. Vertex subquadrate, truncate at base which is 

 about level with middle of eyes, slightly rounded apically, depressed in 

 middle, keels obsolete; face long, slightly convex and keeled laterally, 

 a pair of median keels subobsolete at base, gradually converging to- 

 gether and meeting at apex, no keels on genae; clypeus longer than 

 face, tricarinate, median keel reaching apex, lateral ones reaching 

 a little beyond middle. Pronotum a little shorter than vertex, an- 

 teriorly truncate in middle, posteriorly shallowly emarginate, median 

 keel subobsolete, lateral keels wide apart, diverging, following curva- 

 ture of back of eyes. Scutellum slightly broader than long, lateral 

 angles well in front of middle, 5-carinate, medio-lateral keels con- 

 verging anteriorly. Tegmina narrowly rounded at apex; subcosta and 

 radia amalgamated for basal third, radial cross-vein missing or very
