Type ? (98601, Hammam-es-Salahw?) BM. 



Hah. Algeria : constantine : Hamniam-es-Salaliin, © dates, 

 ex. 18.IV.li:)04 {Lord Walsinghamj : England (n»|)or/ec?) : Loudon, 

 © dates, Xn.l911, ex. 20.VII.1912 (B. Sonth). Two specimens. 



The markings are very indistinct, and not easily traceable ; most 

 nearly allied to imihratella Tr. and unijiiuideUa Chrtn. This species, 

 which will probably prove to be of economic importance, i'eeds on dates, 

 and may be widely spread by commerce like Ej'hestia, Corcyra, etc. 

 Myelois ])lioen.icis was first met with by Lord Walsingham, who bred it 

 in Algeria in 1904; eight years later it was bred by Mr. South from 

 dates purchased in London ; during the present year dates infested 

 by larvae which may belong to this species have been sent from France 

 by Lieut. N. D. Riley, A.S.C., BM.(N.H.).

A NEW AFRICAN BAT-FLEA. 

 BY THE HON. N. CHARLES ROTHSCHILD, M.A., F.L.3. 



(Plate XXII). 



Chiropteropsylla hrockmani sp. nov. 



In Ent. Mo. Mag. (2) XIV, p. 83 (1908), I described as Ceraio- 

 psylla aegyptius a bat-flea from Cairo, which has a comb of black 

 spiuiforin bristles at the posterior edge of the metepimerum. In 1908 

 (Ent. Berieht., p. 102), Oudemans proposed for this species the generic 

 name Gli\roi)feropsyUa . 



The Imperial Bureau of Entomology has received a specimen of 

 a second species, collected in Somaliland by Dr. E. E. Drake-Brockman. 

 This example is a ? and differs considerably in the shape of the head 

 from Ch. aegyptius, of which only one specimen, a ? , is known.
