PERISCELIS ANNULATA, Fall., A DROSOPIIILID NEW TO 



BRITAIN. 



BY C. G. L.\MR, M.A., B.Sc, Zoological Mdseum, Cambridge. 



Several specimens of what was surmised by me to be a Periscelis 

 were seen and taken at sap flowing from a beech tree in the New 

 Forest in June of this year. 'Jhe insect was identified on returning 

 home as being P. annulnta, Fall. Other specimens were obtained at 

 the same tree by Dr. D. Sharp, F.R.S., and Miss M. A. Sharp. About 

 the same date it was also taken at sap flowing from an elm near 

 Cambridge by Dr. F. Jenkinson.

OCHTHERA MANTISPA, Lw., AN EPHYDRID NEW TO BRITAIN. 

 BY C. G. LAMB, M.A., B.Sc, Museum of Zoology, Cambridge. 



A single female of this interesting addition to our fauna was 

 taken by me at Porthcothan, near Padstow in North Cornwall, in this 

 September. The locality is where a small stream flows on to the 

 sands, and is a very good one for Ephydrinidcd. It had been carefully 

 worked in the previous July, and,- as in September, onlv the single 

 specimen was obtained, it is probable that the insect would be better 

 sought for in August. The insect can be readily recognised ; it is 

 smaller than 0.manfis,T)eg., of a grey colour, and has bright red tarsi. 

 It was first described by Loew from specimens obtained in Rhodes, 

 and Becker gives its distribution as Italy, Greece, and Asia Minor. It 

 would appear that O. manfispa is a southern form, and it is of interest 

 to note that the flora of Cornwall gives similar indications of con- 

 nection with the south of Europe.

Occurrence of Celerio lineata livornica, Esp. {Deilephila livornica, Esp.), at 

 St. Leonards, Sussex. — On May 20Lli, 1904, a male example of this species was 

 caught by a boy on the post of one of the street lamps in this town and brought to 

 me alive. Dr. Karl Jordan lias kindly conflnned the identification. I have followed 

 Messrs. Rothschild and Jordan (" A Revision of the Lepidopterous Family Sphin- 

 gidte," p. 732, April, 1903) in using (he name Ce/erio lineata livornica for this form. —
