Altliough Fabricius did not indicate any locality for this 

 type, it nevertheless carries a small round label inscribed 

 " Georgia." The fact that the written surface of the label 

 had been placed in direct contact with the pectus of the 

 dragonfly no doubt led to its being overlooked. The specimen 

 is in an unusually good state of preservation, and the measure- 

 ments are as follows: — Abdomen 39"5 mm., hind wing 49 mm., 

 pterostigma 7 mm. In the fore wings the triangles are 

 3-celled, the subtriangles are 6-celled, and the antenodals 

 number from 161 to 18. At the base of each wing a dark line 

 ill the subcostal space reaches nearly to the third antenodal. 

 The noilal spot on all wings is small, and no markings of any 

 kind lie between that spot and the pterostigma. The brown 

 apical cloud on all wings is small, not reaching inwards much 

 beyond the distal end of the pterostigma. 



XLIII. — A new Voleji-om Palestine. 

 By Oldfield Thomas. 



(Published by permissiou of tlie Trustees of the British Museum.) 



In 1913 the Briiish Museum received as a donation from 

 Mr. N. Charle-s Itothschild six voles from Ekron, south-east 

 of Jaffa, and these were provisionally put down as Microtus 

 syriaciis, Brants. 



Inquiry was, however, made of Prof. Matschie as to certain 

 details of the type of that species, and with the help of his 

 account I am now able to recognize that the Ekron vole is 

 distinct and should be described as new. 



Microtus philistinus, sp. n. 



Like M. li/dins, Blackler, but bullae larger. 



Size and general colour above quite as in M. lydixis, the 

 back sandy brown, rather more buffy than Ridgway's " buffy 

 brown." Sides more buffy, but not so strongly as in lydius. 

 Under surface washed with buffy, more so than in lydius, in 

 which the ends of the hairs are greyish white, less so than 

 in guentheri. Hands and teet buffy fawn. Tail as long as in 

 lydius, longer ihan in yuenthen ; its upper surface terminally 

 lii.-tinctly blackened, which is not the case in lydius ; its 

 lower surface pale buffy — white in lydius.
