Dear Mr. Stelfox, 
Many thanks for the data of the 
Xylota lenta , al so for the box of Syrphidae. Although 
all these have been noted as Irish , they include two 
interesting species- Flaty chlrua scambus Staeg. 
and SriBtalis abusivus Collin 0? The latter is 
uncommon, resembling the common E. arbuatorum. L. very 
closely. For your information, the fflaty chirus is 
from Newcastle, 12 .3. and the Erie tali a is Newcastle, 
5.3 
Syrphidae that you catch this season, 
With kind regards to Mrs. Stelfox 
Yours sincerely. 
and yourself,
