propose a new genevlc name for an insect wliich had received one already ! 

 That uiune, however {'' SaJiIbeiyia Forsius "), has itself been relegated 

 to synonymy, Ur. Enslin having sunk it in his " Tenthredinoidea 

 Mitteleuropas " as a synonym of the older name Hemitaxonus 

 Ashmead. 



I am not myself aeupuiinted with any of the species — all (I believe) 

 N. American — on which Aslimead's genus was founded. But assuming 

 that strutliiojyferidis has been correctly referred to it, it seems that the 

 ])roper " Generic " name of Cameron's insect will be not Slronr/i/logaster, 

 nor (as above suggested provisionally) Pseudotaxomis, but ILemitaxomis 

 Ashm. Since, however, it was described long before strutliiopteridis, 

 its "Specific'' naure will still be sliari)i, whether or no the two insects 

 be identical.

ODONATA COLLECTED IN NOETH-WESTEEN PEESIA AND 

 MESOPOTAMIA BY CAPTAIN P. A. BUXTON, E.A.M.C. 



EY KKNNETll .T. ilOKTOX, F.E.S. 



My thanks are again due to Captain P. A. Buxton for another 

 interesting lot of dragon -flies, the greater part in this instance collected 

 in 1919 in the Soutliern Caspian region of North-Western Persia, mostly 

 from round about Enzeli, the port of liesht, in the province of Gilan. 

 The remainder are from Mesopotamia, and although these comprise no 

 -species new to the fauna of that countr}^ yet the additional data ma}^ be 

 useful, forming in this respect a continuation of my notes in Ent. Mo. 

 Mag. 1919. 



The fauna of i\\e Caspian provinces of Persia is, I suppose, on the 

 whole Palaearctic in character, and the Odonata are quite in accord. 

 With the exception of Calopteryx orientalls, Flatycnemis latipes 

 ilcalhata, and Ortlietrum sahiiia, all the species from this region in- 

 cluded in the collection are found in Europe. Previous records from 

 the Caspian, and from the Caucasus and Turkestan are here given, but 

 it is not claimed tliat these are exhaustive, even with respect to the 

 species mentioned. It may be mentioned that, according to an analysis 

 of a manuscript note by Pallas upon the Odonata of the liussian Empire, 

 ■communicated to de Selys by Hagen, it is probable that O. sahiiia may 

 <xlso be found in southern Russia, perhaps Euroi)ean, and such an occur- 

 ii-encc seems veiv likely, but I can find no trace of a definite record. In
