o20 On neir Species of Plecotus. 



German East Africa : type and two other specimens from 

 Nguelo, Usamhara (purchased from Hermann Rolle). 



The striking markings and coloration of this species are 

 sufficient to distinguish it without difficulty from any other 

 African Chrysops at present known. 



Synonymical and other Notes. 



Chrt/sops tarsalis, Walk., = C. longicornis, Macq., as 

 suggested bv Gerstaeeker (Baron Carl Clans von der Decken's 

 'Reisen in Ost-Afrika/ Bd. ii. Abth. 3, 1873, p. 384). 

 Miss Ricardo (A.nn. & Mag. Nat. Hist. ser. 7, vol. ix. 1902, 

 p. 368) is mistaken in regarding the two species as distinct. 



Chrysops trimaculatus, Bigot, = C. lonfficornis, Macq. 

 Through the courtesy of Mr. G. H. Verrall, in whose collec- 

 tion it now is, I have been enabled to examine Bigot's type, 

 which is a cJ , not a ? , as stated by the author and by 

 Miss Ricardo [loc. cit. p. 371). 



Chrysops fnscus, Ricardo (loc. cit. p. 368). — The type and 

 remainder of the original series of this species are males, not 

 females, as stated by the author. 



LXXV. — Descriptions of Two new Species o/ Plecotus. 

 By G. E. H. Barrett-Hamilton. 



Amongst the bats in the British lluseuin of Natural History 

 I fiiul two nndescribed species of the " Long-ear." They 

 may be characterized as follows : — 



Plecotus teneriffa'j sp. u. 



This bat resembles P. auriius of Britain, but lias much 

 larger wings. The colour is apparently darker, but cannot 

 be taken as reliable from the old dried skin upon which this 

 description is based: it is, above, near Ridgway's "hair- 

 brown," the hair-tips lighter; below, dirty yellowish white, 

 the dark basal portions of the hairs not evident. 



The type has no skull. 



The dimendons (in millimetres) of the type are as 

 follows : — 



Head and body 52 ; tail 45 ; ear from the notch 35 ; 

 tragus 14; thumb without claw 6 ; longest digit 73; basal 

 joint of fifth digit 35 ; basal joint of second digit 37; lore- 

 arm 44 ; tibia 18"5 ; hind foot (without claw) 8. 



Hab. Teneriffe.
