ORTROPTERA OF MESOPOTAMIA AND PERSIA. IQl 



Legs concolourous, rather short and stout. Front femora thick, armed 

 beneath with 3 small black spines on the inner edge ; tibi« longer than the 

 femora, armed above with 3 external spines, beneath with 6 rather strong ones 

 on each side ; tarsi very short, the metatarsus scarcely longer than the 2nd 

 joint. Intermediate femora longer than the anterior ones, bearing, like those, 

 3 very small black spines beneath ; tibiee armed above with 2 external, 4 in- 

 ternal spines, beneath as the anterior ones. Posterior femora short and stout, 

 armed beneath with 4-5 small black spines on the outer edge, 2-3 on the inner 

 edge ; tibiae a little shorter than the femora, with 4 apical spurs and 6-7 small 

 spines inserted in a black spot on each inferior margin, the apical ones much 

 longer than the others ; about 25 spines on each superior margin ; tarsi 

 short, the free plantulse equaling scarcely half the length of the metatarsus. 



Elytra extending in both sexes a little beyond the apex of the 1st abdominal 

 tergite ; they are brownish with blackish spots between the anastomosed 

 veinlets which are very numerous ; S with 3 lateral veins ; humeral vein 

 simple, thick, sinuate near the apex ; discoidal vein furcate ; 5 with 2 lateral 

 veins and 3 dorsal ones. 



Length of body, d",25mm., $ , 26 mm ; length ofpronot., 8 mm.; ant. tem., 

 65 mm. ; ant. tib., 7'7 mm. ; interm. fem., 8-5 mm. ; interm. tib., 8*5 mm. ; 

 post. fem. 21*5 mm. ; post. tib. 20*5 mm. ; o\ipos., 13 mm. 



This species is very distinct by reason of its stout stature, the small black 

 spines of all the femora, the very short free plantulce of the posterior metatarsi, 

 the form of the anal segment of the male and the brevity of ovipositor. It might 

 perhaps enter the genus Ariagona Krauss, previously known from a single 

 canarian species, as well as Pholidoptera.

This species is known only from the female ; the specimens here referred to 

 have been identified by M. B. Uvarov himself, who had the kindness to send me 

 the undescribed male. 



(5 (Macropterous). Slender, smaller than the female, almost unicolourous 

 testaceous. Anal segment very deeply and acutely divided at the apex, 

 forming two long acute processes, the basal part of the tergite angularly 

 folded ; sub-genital plate large with two longitudinal keels, apex deeply and 

 narrowly notched, presenting above two small black lines along the sides of the 

 hollow ; styli rather long, C54indrical. Cerci stout, as long as the processes of 

 10th tergite, narrowing towards the apex, bearing at their proximal third a 

 strong internal tooth. Titillators slender, strongly curved, armed with a few 

 small spines. 



Length of body, 18*5 mm. ; length of pronot., 4*8 mm. ; elytra 20-5 mm. ; 

 post fem., 18 mm. ; post, tib., 165 mm. 



Gen. — Paradrymadusa, Herman. 



Paradrymadusa qazvinensis, n. sp.

Types:— One male from Persia Qazvin, (P. A. Bxtxton, Nov. 1918) and one 

 female, same locality (P. A. Buxton, 17, July 1919). 



Large species, testaceous or rufous broAvn. Occiput concolorous ; apex ot 

 vertex not much broader than the first article of antennae ; face yellowish.
