P. filiformis, Mayr. (Plate I., fig. 2, 2a.) 

 Loc. cit. 

 $ . 3 mm. Head nearly twice as long as wide, posterior angles 

 feebly rounded. The anterior portion of the head is produced into a 

 roof-like projection or ledge which reaches as far as or a little 

 beyond the apex of the closed mandibles. This projection is formed 

 by the clypeus and the anterior portion of the fused frontal carinae 

 and all that part of the face which lies between a point' a little 

 behind the antennal sockets, and the anterior margin of the clypeus. 

 Viewed from the side, the antennae are seen to be inserted on this 

 ledge half-way between its anterior and posterior limits, and 

 therefore lie above the middle point of the mandibles when the 

 latter are closed. The frontal carinae which arise a little in front of 

 the antennal sockets, leaving them uncovered, are curved inwards,, 

 fused together for half their length, diverge again posteriorly and 

 reach to a point about as far back as the base of the mandibles. 

 The fused portion of the carinae forms a rounded and raised crest, 

 lying between the insertion of the antennae. The latter are 

 12-jointed ; the scape, somewhat flattened, reaches back two-thirds 

 of the head ; the flagellum is gradually thickened towards the apex. 

 The last joint is twice as long as the two preceding, and all the joints 

 except the 1st and 3rd, are noticeably wider than long, the 1st joint 

 is two-thirds as long again as it is wide, the 3rd joint is about as- 

 long as wide, and the 2nd joint is very small and nearly twice as- 

 wide as long. 



The colour is a rich burnt sienna, with the antennae, legs, and 

 apex of abdomen lighter, or ferruginous yellow. The whole body is 

 dull and microscopically and densely punctulate, intermixed with 

 larger and shallower punctures on the 1st and 2nd abdominal 

 segments and the back of the head. The general puncturation is 

 only observable with a magnification of 60 diameters, and the larger 

 punctures are barely recognizable under a magnification of even 20 

 diameters.
