 from New Guinea, and P. ahnormis, Crawford, from the 

 Philippine Islands.

 antennal scape bright reddish-yellow ; the tarsi and antennal 

 funicle paler yellow. Head very flattened, the vertex very 

 thin ; viewed from in front the head is large, circular, with 

 a deep groove running down the centre from the vertex, and 

 branching in two towards the insertion of the antennae. Eyes 

 large. Antennae 12-jointed : scape almost triangular, broad- 

 ening on the outer side into a sharp point at the apex, where it 

 is nearly as wide as long, and much wider than any of the 

 other joints ; pedicel and first funicle-joint subequal, longer 

 than wide ; second and third funicle-joints wider than long ; 

 fourth and fifth very transverse ; club 5-jointed, very pro- 

 nounced, the joints much wider than long, fourth the widest. 

 Thorax flattened, long ovoid ; pronotum viewed from above 

 reaching back as far as the insertions of the forewings ; meso- 

 notum with two deep parapsidal furrows, parallel, wide apart ; 

 mesonotum with fine longitudinal lines of hairs : scutellum 

 short ; postscutellum very short. Forewings long, but not 

 reaching to the apex of abdomen ; moderately broad ; infus- 

 cated, the infuscation deepest towards the costa ; discal cilia- 

 tion arranged in about forty rows ; venation very thick ; sub- 

 marginal vein attaining the costa at about two-fifths wing 

 length ; marginal vein long, twice as long as the stigmal, 

 which is very oblique, short, terminating abruptly ; postmar- 

 ginal and basal veins wanting. Abdomen flattened ; longer 

 than the head and thorax united ; wholly clothed with longi- 

 tudinal rows of fine hairs; segments 2-5 equal in length. 

 Legs rather stout ; tibiae as long as their tarsi ; basal joint of 

 posterior tarsi eight times as long as the second joint. Length,
