been enabled to inspect his speeimens of L. ngirifrons (a (J and ? in bad condition), 

 and I have much pleasure in stating that the identification is undoubtedly correct. 

 This is, perhaps, not suprising, since Mr. Dale informs me that they were named by 

 the late A. H. Haliday. 



Next to Loxocera nigrifrons, Macq., and L.fulviventris, Mg.,the least common 

 British species (so far as it is possible to judge from the present state of the Museum 

 collection) appears to be L. sylvatica, Mg., of which we possess eight examples, all 

 taken at various localities in S. Devon (Bickleigh Yale, Shaugh Bridge, Ivybridge, 

 and Plymbridge), on dates ranging from April 20th to May 19th (collected and 

 presented by Lieut. -Col. Yerbury). 



The commonest British species of Loxocera is L. albiseta, Schrk., which in size 

 ranks next to L. aristata, Pz. In this species the abdomen of both sexes is cylin- 

 drical, since, except at the extreme tip (the actual ovipositor), that of the ? is not 

 laterally compi-essed, as it is in L. aristata. Of L. albiseta the Museum possesses 

 some two dozen specimens, taken at various localities in the Western, Southern, and 

 Eastern (Wicken Fen, Cambridgeshire) counties of England, on dates ranging from 

 June 26th to September 23rd {Lieut.-Col. Yerbury ; A. Piffard ; E. E. Green). 



A search through the volumes of the " Zoological Record " shows 

 that since the date of Schiner's Catalogue (I86i) only three European 

 species of Loxocera have been described, viz. : — maculata, Rond. (Bull. 

 Soc. Ent. Ital., viii, 1S76, p. 193), from Italy ; marginata, Eond. {loc. 

 cif., p. 194), from the Apennines; and atriceps, Bigot (Bull. Soc. Ent. 

 Fr, (6), vi, 1886, p. Ixxxv), from Chapuy, near Mt. Blanc. Whether 

 any of these are synonyms of the five species previously described 

 and tabulated above, or whether any or all of them will eventually 

 prove to be members of the British fauna, are matters for future 

 investigation.

TWO SPECIES OF EPHEMERID^ NEW TO BRITAIN. 

 BY C. A. BEIGQS, F.E S. 



During the stay of Messrs. King, Porritt and myself at 

 Camghouran— as Camachgouran is now spelt — from June 7th to 2l8t 

 last year, I collected specimens of such of the Ephemeridcs as came in 

 my way, but, owing probably to the very cold weather shortly before 

 our visit, they were not so numerous as I had hoped. We were in fact 

 too early for the majority of species. 



I have recently submitted my specimens to the Eev. A. E. Eaton 

 who has most kindly not only named them for me but furnished mo
