joitits: niesotlioracic furrows complete, stroiifrly couverginfj to about three-fourths 

 the lengths of the niesouotum and then with an abrupt curve towards the inner 

 one-third of the axillae; scutellum with an indistinct cross furrow before apex; 

 nietanotuni and abdomen as in P. tri/petse, but with the abdominal segments rela- 

 tively ditferent : The second segment occupies more than half the whole surface, 

 the third being one-half longer than the fourth, the fifth only one-half the length 

 of the fourth, vvliile the following segments are retracted.

 scai)e and tarsi, yellowish. Legs, except cox aj and tarsi, rufous ; tlagellum brown- 

 black. Wings amj>le, hyaline, pubescent, the anterior pair with a dusky spot at 

 their basal angles ; tegulie piceous; veins yellowish, the marginal vein about two- 

 thirds the length of the submarginal, the stignial vein about one-third the length 

 of the marginal, ending in a small knob with iin uncus, the postmargiual very 

 long, extending to the apex of the wing; collar distinct, narrowed, eampanulate i 

 mesonotuni rather flat above, with complete parapsidal furrows; scutellum flat-
