 ceeding in length the succeeding joints ; the second to fourth 

 joints of the mid tarsi also grooved and flattened ; the poste-

Type in the St. Petersburg Museum. 



A singular species, belonging to the same group as P. afi-i- 

 cana, L., but differing in the peculiar tarsal structure and in 

 the single row of spines on the inner aspect of the hind tibias, 

 a character alsD presented by the genera Anisogamia and 

 Nymphrytria.

? . Form ovate, depressed. Head very flattened, frons 

 highly polished ; testaceous. AntennjB pale testaceous. 

 Pronotum hyaline, with two broad rufescent vittse ; very 

 broad in proportion to length, anteriorly broadly emarginate, 

 so that the vertex of the head is freely exposed, posteriorly 

 truncate, exposing the small testaceous scutellum. Tegmina 

 and wings not exceeding apex of abdomen. Tegmina with 

 very broad hyaline marginal area, disc rufescent; mediastinal 

 vein very robust, extending throughout two-fifths of the 

 tegmen-length, but failing to reach the outer margin, the first 

 three costals abutting on it ; radial vein simple, 9 costals, 1 

 ulnar vein with 4 oblique rami, the discoidal and anal areas 

 reticulated. Wings hyaline ; radial vein curved ; 10 costals, 

 all rising from the posterior third of the radial vein, their 

 apices incrassated, forming a conspicuous " stigma " ; medio- 

 discal area twice as broad as medio-ulnar area, crossed by a 

 few transverse venules; ulnar vein biramose, the rami united 

 by anastomoses ; a large apical area, its base acutely angu- 

 late, in repose folded on the top of the wing. Abdomen 

 rufescent above, testaceous beneath, broad ; supra-anal 

 lamina triangular, deeply incised at the apex ; subgenital 

 lamina ample, posterior margin widely and faintly emar- 

 ginate. Cerci long, rufo-testaceous. Legs testaceous. 



Total length 8 mm.; length of tegmina 6'5 mm.; pro-
