Mas. Testacea out viridis, gracillima, fere linearis ; caput lanceolatum, 

 prothorace longius, antice subsulcatum ; antenna nigrce, lanceolatce, 

 basi testacece, non dilatatce ; protlwrax planus, subcarinatus, lateribus 

 perparum serratis, pedes yraciles, spinosuli ; alee anticce angustce, per- 

 acutce ; alee poslicce diaphance, breviores. 



Male. Testaceous or green, very slender, nearly linear. Head 

 lanceolate, longer than the prothorax ; fore part elongate-conical, much 

 longer than the eye, very slightly furrowed. Eyes fusiform, not promi- 

 nent. Antennae lanceolate, black, testaceous at the base, not dilated, 

 much longer than the head. Prothorax flat above, with slight keels; fore 

 border slightly truncated ; hind border rounded ; sides very slightly 

 serrated. Legs slender; four anterior tibiae with a few extremely minute 

 spines; hind tibiae with two rows of minute spines. Fore wings narrow, 

 very acute, much longer than the hind wings and extending much beyond 

 the abdomen. Hind wings pellucid. Length of the body 10 lines ; 

 expansion of the fore wings 20 lines. 



The longer fore part of the head distinguishes it from P. crenulata and 

 from P. parabolica.
