Only the basal three joints of the antennae are present. Face and 

 clypeus strongly and closely punctured ; the clypeus less closely 

 than the face ; both are covered with short black pubescence ; the 

 front and vertex are more strongly punctured. Pro- and mesothorax 

 strongly and closely punctured ; the base of the pro- and the apex of 

 the mesopleurae more or less striated. Scutellum large, rounded, 

 shining, distinctly, sparsely punctured, the apex strongly, closely 

 longitudinally striated. Metanotum closely, rugosely punctured ; 

 depressed in the middle at the base ; the areola large, slightly longer 

 than broad, of equal width throughout, transverse at the base, the 

 apex slightly turned inwardly in the middle. Post-petiole broad, the 

 centre closely longitudinally finely striated ; the sides somewhat 

 strongly punctured ; the other segments are closely punctured, the 

 punctuation becoming weaker ; the gastrocceli transverse, deep. 

 Areolet 5-angled, half the length of the apex in front ; the recurrent 

 nervure is received near the base of the apical third ; the transverse 

 median nervure received shortly beyond the transverse basal ; the 

 •disco-cubital nervure is broken by a minute stump. ^letathoracic 

 spiracles large, linear. Last abdominal segment longer than the 

 penultimate. Temples wide, roundly naiTOwed. The ai'eae on the 

 metanotum are indistinct. 



This species closely resembles P. pcringucyl ; the main differences 

 between them may be expressed thus : — 



Basal joints of antennae black ; temples straight, obliquely 

 sharply narrowed, scutellum convex, its apex punctured, disco- 

 cubital nervure with a long stump perUKjueyi. 



Basal joints of antennae red ; temples rounded, not much nar- 

 rowed, scutellum not much raised, the apex striated ; disco- 

 cubital nervure with a minute stump erythroajjilus.

 tinged with rufous ; a mark on the sides of the face, longer than

 the clypeus pale yellow, the labrum hidden, yellowish testaceous ;
