new Species of Blattidse. 11 



3 spines on the inner aspect arranged in a single oblique row, 

 7 apical spines, the longest exceeding in length the first 

 tarsal joint. Tarsi elongate, the metatarsi of the first and 

 second pairs of legs flattened and grooved, considerably ex- 

 ceeding in length the succeeding joints ; the second to fourth 

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

 rior metatarsi not grooved, shorter than the first and second 

 pairs. Claws slender, without arolia. 



Length 16 mm. ; greatest breadth 11 mm. ; pronotum 

 6 - 5x 8*1 mm. 



Tunis, Gafsa. 



Type in the St. Petersburg Museum. 



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

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

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

 a character alsa presented by the genera Anisogamia and 

 Nymphrytria. 



C7wrisijieura australlca, sp. n. 



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

 highly polished ; testaceous. Antennae pale testaceous. 

 Pronotum hyaline, with two broad rufescent vittoe ; 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 " ; mcdio- 

 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- 

 notum 2 x 3 - 8 mm.
