as in that species; the middle face-mark, however, is much larger 

 and broader below, and at this point the head is more protuberant 

 than in P . bilunatiis; there is a spot behind eye, and below teguhie, 

 yellow. Abdomen with the first segment showing two small 

 spots, the second segment with a very broad band, almost divided 

 in the middle; third and fourth bands narrow, and emarginate 

 each side in front. Last segment more emarginate than in P. 

 bilunatiis. Legs with femora (except tip) black, rest of legs yellow. 

 Wings infuscate, rather broader than P. hilunatus, the third sub- 

 marginal as broad as long; \'ertex broader than in P. hiliinatiis. 



Length 10 mm.
