tlie apex, the sides raised and forming carinse^ within which 

 are two cariiiai converging towards the apex and enclosing an 

 inner rugulose area, raised above the lateral margins. The 

 first recurrent nervare is rather nearer to the second cubital 

 cell than in the male.

The male is the type. 



In the almost complete absence of the appendix to the 

 radial cell this species agrees with latifrons^ Kolil. The 

 second cubital cell is very narrowly triangular, so that the 

 distance between the recurrent nervures is no greater than is 

 usual in the genus, although in this species the tirst recurrent 

 is received by the first cubital cell. The third cubital cell 

 is almost rectangular. In the form of the apical segment 

 in the male the species is isolated, differing from all others, 

 the dorsal plate being much broader than in P. saundersi, 

 Morice, the only other species, so far as I know, in which 

 there are no spines or bifurcation. 



P. saundemi may prove to be the male of dongalensis,

The United States National Museum contains one of each 

 sex, collected by T. Fukai at Horisha, Formosa. I also find 

 a male in the Sauter collection from the Berlin Museum, 

 collected at Kanshirei, Formosa, June 8, 1908. The male is 

 about 13 mm. long, narrow, with pubescence much as in the 

 female, the abdomen with narrow entire red hair-bands, and 

 some red hair in the basal depressions of the segments, the 

 face with much red hair, the vertex and disc of thorax with 

 a good deal of black hair. The mandibles are quadndentate, 

 the teeth sharp, the second one smaller than the others ; 

 antennse long and black ; anterior coxae with short spines, 

 hidden among the hairs ; anterior tibise and tarsi simple ; 

 sixth abdominal segment retracted, its upper surface granular, 

 elevated in the middle, and with only scattered erect dark 

 hairs in the Kanshirei specimen, but in the other with some 

 appressed pale yellow tomentum in the middle; margin of
