Long : fi^re 7 m.m. 



Habitat : Deesa. 



Antennae black, stout ; the scape and second joint straw -yellow ; the 

 flagelluui brownish beneath towards the apex and base. Head black ; 

 the verteix smooth, shining ; the front minutely and closely punctured; 

 the lower part of the face and the clypeus thickly covered with 

 depressed silvery pubescence; between the autennge is a stout, project- 

 in ii; keel, which becomes triangularly widened below the antennas. 

 Mandibles and palpi straw-yellow ; the mandiuular teeth black ; the 

 palpi yellow. Thorax shining ; the edge of the pronotum, the tubercles, 

 SGutellum and post-scuteJlum straw-yellow. Median segment reticu- 

 lated, broadly furrowed down the middle, the farrow not margined ; the 

 base of the segment is smooth ; the narrow depression at the base is 

 striated ; pro- and meso-pleurse smooth and shining ; the furrows crenulat- 

 ed ; the mntapleuise reticulated ; the reticulations are closer and more 

 regular than they are on the metanotum. The four front legs are straw- 

 yellow, as are also tiie hinder tibi^ ; the hinder cosee, except at the 

 apex, the femora, the apex of the tibiae and of the tarsi, black. Wings 

 clear hyaline; the first and second ti'ansverse cubital nervures are 

 parallel and oblique ; the first recurrent nervure is interstitial ; the 

 second is j-eceived shortly beyond the second transverse cubital, almost 

 touching it. x\bdomen black ; the second segment is rufous to shortly 

 beyond its middle ; the petiole is longer than usual, being aa long as 

 all the rest of the abdomen united in the $ ; it is largely nodose at 

 the apex. 



This species is easily known by the presence of a pointed plate be- 

 tween the antennae. The only species known, similarly armed, is 

 P. annuUpes^ Cam., from Central America, for which Kohl. (Ann. d. k. 

 k. Hof. Mus. Wien, 1896, p. 292) formed a distinct section of the 

 genus. Apart from this structural peculiarity it differs from the other
