I have been in doubt as to the genus to which this interesting insect belongs : 

 in its general appearance it seems to be an Oedipodid, but the position and form 

 of the tempora, which are most clearly contiguous and forming the extremity of 

 the fastigium, indicates its place among Pyrgomorpliidce, near Chrotogonus. The 

 nearest known thing is Leptoscirtus angustus, Blanch. ( = L. savignyi, Sauss) 

 and after a careful study of the unique specimen of the latter species in the 

 British Museum, I came to the conclusion that my species is to be placed in the 

 same genus. It is obvious, also, that Saussure was wrong in placing Leptoscirtus 

 in Oedipodidce, since the genotype of this genus is L. angustus — a Pyrgomorphid; 

 on the other hand the remaining two species which are included in the genus 

 Leptoscirtus by Saussure — L, unguiculatus, Sauss. and L. aviculus, Sauss., are 

 doubtless (Edipodidse and ought to be withdrawn from this genus. Thus, 

 the genus Leptoscirtus (of Pyrgomorphidse) includes in it two species only : L. 

 angustus, Blanch, and L. evansi. * The genus itself is well characterised by 

 the short fastigium of vertex, by the antennae composed of 8-9 articles while the 

 terminal article is very long and incrassate, and by long spurs of the hind tibiae. 

 The new species is quite easily separated from L. angustus by more markedly 

 anarginated tempora, by the characteristic callosities on head, pronotum and 

 elytra, by the 8-jointed antennse, &c. 



This remarkable insect is truly desert in its habitation, being discovered by 

 Mr. Evans on gravely slopes, where it ought to be exceedingly well protected by 

 its coloration and habits. 



28. Tropidopola cylindrica. Marsh. — Amara, 30-10 — 1-11-17; 10-4 — 2-.5-18 

 — Qalatsaleh, 6-1-18 (Dr. Buxton) ; grassy ground near Tigris, Amara, 

 31-10-17 (Mr. Evans). 



29. Derocorys gibbosa, Fisch. -Wald. — River Tigris, 8 miles above Amara, 



uncultivated ground, 10-9-18 (Mr. Evans). — This species has been 

 known so far only from Aralo-Caspian deserts. 



30. Acrydium cegyptium, L. — Enzeli, 10.-4-19 ; Amara, 30-9 — 27-10-17 (Br- 



Buxton); Masharra Canal, Amara, on willows, 5-9-18 (Mr. Evans). 



31. Schistocerca gregaria (Forsk.) {■=peregrina, 01.) — Enzeli, 24-5-19, "migar- 



nt? " (Dr. Buxton) ; courtyard, Beit Na'Ama Hospital, Basrah, 5-4-19. 

 (Mr. Evans). — Mr. Evans remarks that '"a flight of this species appeared 

 at Basrah in April 1919." The supposition of Dr. Buxton that the Enzeli 

 specimen belongs to a migrating swarm ought to.be true, since this 



* It is possible that some species of Chrotogonus with small number of joinla 

 of antemiEe ((7/t. sa?;/(7?j?/?, Burm., for instance) might be replaced in Leptoscirtus, 

 but it can be done after study of specimens only.
