38.* Pteronemobius heydeni (Fisch.). 



Nar ez Zerka, i/j Apr.; Beisan, 4 January; Jeiiin, 

 21 March; Caesarea, 22 March. 



This species is quite common in rank grass at 

 the edge of slow streams and ponds; it is most easily 

 caught by shaking the vegetation over the water. 



Pt. heydeni is a well-known South-European 

 and Mediterranean species ranging also into Asia 

 Minor, Caucasus and Turkestan, and it is remarkable 

 that in the latter country it occurs only[ in a fully 

 winged form, subsp. tartarus Sauss. ( = vittcncli, 

 Beri, et Chop.; see Uvarov, Trans. Ent. Soc. London, 

 1923, p. 1/16), while in the Caucasus and in Pales- 

 tine as well, this form occurs together with the typi- 

 cal subsp. heydeni which differs only by its un- 

 developed wings; the most western locality where 

 subsp. tartarus has ever been found is Macedonia and 

 farther westwards only subsp. heydeni is known. Tt 

 seems not improbable that macropterism in this 

 species may be due to the comparative dryness of 

 environment. 



39. Liogryllus bimaculatus (De Geer). 



Jerusalem, i/i June, 17 Sept., 12 Nov.; Nahr cz 

 Zcrka, i4 Apr. 



This species is quite common under stones and 

 also flies to light. 



It seems highly probable that Giglio-Tos mistook 

 this species for L. campestris L. as no other record? 

 of the latter from Palestine are known,
