ORTKOPTERA OF MESOPOTAMIA AND PERSIA. 763 



tibiae are armed with 9 superior spines, the three distal ones forming a group not 

 very clearly separated from the other 6 ; 4 inferior spines inserted in the distal 

 half of the tibia, of which 2 external and 2 internal, the latter much longer. 



The female specimens seem to belong to the same species, showing the same 

 tibial armature ; there is no tarsal arolia but this must be characteristic of the 

 females of all the species of this genus. The adult specimens are covered with 

 a reddish hairy clothing and show the supraanal and subgenital plates shghtly 

 notched at the apex. 



PolypJuiga persica, n. sp. 

 (Fig. 14 and 16). 

 Type : — One male from Persia, Qazvin, 4-9-1919 (P. A. Buxton). 

 Size medium, form rather short and stout, coloration testaceous brown with 

 numerous small brownish spots on the tegmina. Head hidden by the pronotum ; 

 occiput and forehead black ; facial shield and clypeus yellow, the former 

 depressed, the latter forming a protuberance with a fine median furrow. Eyes 

 large, black, as distant one from the other as the ocelli ; these are very large, 

 yellow, oval ; between them is a tuft of reddish hairs. Maxillary palpi 

 testaceous, the last joint much shorter than the fourth one. Antennae 

 brownish, thick. 



Pronotum rather wide, testaceous, covered with long reddish hairs ; a narrow 

 band along the anterior border ahnost transparent, posterior part somewhat 

 darkened, 8 small black spots on the disk which is convex ; anterior margin 

 slightljr produced in the middle, lateral margins almost straight, posterior one 

 convex. Mesonotum testaceous, its posterior margin subangidate, its exposed 

 part very large, brownish. 



Abdomen broad, depressed, testaceous above, yellowish with reddish hairs 

 beneath. Supraanal plate small, subtriangular, its posterior margin sinuate, 

 apex feebly notched ; subgenital plate a symmetrical, its posterior margin 

 sinuous, thick, covered with reddish hairs ; styli irregular, the right one much 

 shorter than the left which is inserted in the concavity of the margin. Cerci 

 very short, testaceous. 



Legs yellowish ; anterior femora provided with very long hairs and a few 

 spiniform bristles on the inferior inner edge ; tibiae very short, armed with 

 8 strong spines round the apex and 1 on the superior margin ; tarsi long, rather 

 slender, the metatarsus equaling the other joints together ; no arolia between 

 the claws. Intermediate and posterior femora provided with long bristles, 

 without genicular spines ; intermediate tibiae with 7 very long apical spurs, 7 

 superior (4 ext., 2 med., 1 int.) and 1 inferior spines ; posterior tibiae wth 7 

 apical spurs, 10 superior (4 ext., 3 med., 3 int.) and 4 inferior (2 ext., 2 int.) 

 spines, the superior ones forming 3 imperfectly limited groups. Tarsi longer 

 and thinner than the anterior ones, the metatarsi longer than the other joints 

 together. 



Elytra and wings extending beyond the apex of abdomen. Elytra veiy 

 broad, chiefly near the apex, subhyaline with many Httle greyish spots ; mar- 

 ginal field narrow, whitish ; humeral, median and ulnar veins with numerous 

 parallel branches. Wings slightly smoky, chiefly towards the apex and along 

 the anterior margin ; anal angle very pronounced. Veins brownish ; median 

 vein emitting 9 branches, ulnar vein with 13 branches ; many of the radiate 

 veins are fiu'cate. 



Length of body, 15-5 mm.; length of pronot., 4-5 mm.; width of pronot., 7 

 mm.; length of eljiira, IS'O mm.; width of elytra, 6'5 mm. 



This species has exactly the same form and size as the preceding ; it differs 

 from it by its general colour and by the absence of arolia between the tarsal 

 claws. The hook of the genital valves (fig. 13-14) is much thicker and more 

 curved in africana than in persica.
