ROTIFERS. 
Yorkshire Micro -Biology Committee. — The following 
should have appeared in the Annual Report of the Yorkshire 
Naturalists’ Union, printed in The Naturalist for January : — 
J. W. H. Johnson reports the lack of rain during the past 
season has not been favourable to those interested in the 
aquatic forms. In spite of these conditions, Mr. Chas. Barlow 
has furnished a good list of rotifers, found by him in the Pateley 
Bridge district. Mr. E. Percival, of Leeds University, 
records the occurrence of Trypanosoma lewsii among rats in 
the Leeds area ; large quantities of sexually mature Hydra 
viridis from Sandhills, Thorner, and also Vortex viridis from 
pools in the same district. As many of the older members 
are unable to take an active interest in the work of this section, 
it is now desirable that other members should proffer assist- 
ance. — J. W. H. Johnson. 
ENTOMOLOGY. 
Necrobia rufipes at Newsome. — Living specimens of 
this beetle were handed to me by our local schoolmaster, 
captured in his house, on the 20th November last. I am 
indebted to Mr. M. L. Thompson for determining the species, 
which is new to the Huddersfield district. — W. E. L. Wattam. 
Lancashire and Cheshire Entomology. — At a recent 
meeting of the Lancashire and Cheshire Entomological 
Society, Mr. A. E. Wright exhibited the Tineid moth, Blasto- 
basis lignea Wslm. and its variety adustella Wslm., taken in 
North Lancashire and new to Britain ; also a specimen of 
Eromene ocellea, captured at light at Grange in September last. 
Mr. W. Buckley shewed a series of Lycaena icarus, and a 
specimen of the under -side var. radiata, all taken at Delamere 
last May. Mr. W. Mansbridge shewed the best forms selected 
from a very large number of Peronea hastiana, bred last autumn 
from larvae found on the Lancashire coast ; vars. autumnana, 
albistriana, leucopheana, mayrana, combustana, divisana and 
radiana were represented. Mr. R. Tait read the Presidential 
address entitled ‘ The Life -history of Agrotis ashworthii up 
to date.’ Mr. W. Mansbridge exhibited a short series of 
melanic Tephrosia consortaria bred from a female taken at 
Wimbledon by Mr. A. W. Buckstone in 1920. — Wm. Mans- 
bridge, Hon. Sec. 
FUNGI. 
Pluteus cervinus (Schoeff.). — Early in October, 1921, 
four ‘ typical well-grown specimens ’ of this fungus appeared 
in my garden, for the identification of which I am indebted to 
Mr. Alfred Clarke. Although it is described as a common 
species, it appeared on a manure heap, where there are neither 
‘ old stumps nor rotting trunks,’ The pileus of each specimen 
measured four and a half inches across, although sometimes 
larger specimens are found. — Charles Mosley, Huddersfield.
