82 Yorkshire Naturalists Union: Annual Report, 1912. 
COLEOPTERA COMMITTEE.—Mr. E. G. Bayford, writes: 
The general consensus of opinion expressed by numerous 
correspondents is that the exceptionally wet collecting 
season has resulted in an appreciable scarcity of insects. Many 
of the places usually visited have been unapproachable owing 
to floods. Notwithstanding this) when we come to consider 
the net result of the year’s work, we are faced with the 
most surprising fact that we have one of the largest lists of 
additions to the County list ever reported. These number 23, 
two of which have not previously been recorded from the 
British Isles. Eleven of these new records are due to the energy 
displayed by Mr. E. C. Horrell, of Scarborough. The most 
important of them is Chaetocnema conducta, a pretty little 
Halticid of which Mr. Horrell took two specimens by sweeping 
in Forge Valley. Four are due to Dr. Corbett’s industry, 
three to Dr. Fordham and two to Mr.’ Thompson ; one has 
been added by myself, while Mr. Stainforth and Mr. Walsh 
together took a large number of specimens of Helops pallidus 
which, in its way, is one of the most interesting additions to 
the list. In addition to these species new to the County list, 
thirty-five others are new to the Riding in which they have 
been taken. One species has been met with in two of the 
Ridings for the first time. The full list of the most interesting 
occurrences will be sent to The Naturalist. 
HYMENOPTERA, DiIprERA, and HEMIPTERA COMMITTEE.— 
Mr. W. Denison Roebuck writes :—The only notes on Diptera 
are records of Bombylius major and Cnorrhina floccosa at 
Keighley, by Mr. Rosse Butterfield. 
The same observer has sent in reports of Hymenoptera 
for the season, with a list of 14 _Ichneumonids and one Sawfly, 
a few of which are new to the list, asis also Polyclistus mansuetor 
Gr. taken in Leeds by Mr. Walter Withell. Observations on 
the occurrence of bees, etc., durig the season have been made 
by Mr. Butterfield at Keighley, Mr. John F. Musham at 
Selby, and Mr. A. E. Bradley and Mr. Roebuck at Leeds. 
The general result shows that the season has not been a favour- 
able one except in April and May. The outstanding feature 
of importance in the year’s work has been Mr. E. G. Bayford’s 
capture of an ichneumon, identified by Mr. Claude Morley, 
F.E.S., as Nemeritis canescens Grav. The species is most 
probably parasitic upon Ephestia kuehniella L. which is a 
common moth in the flour mill at Barnsley in which the ich- 
neumon was found. Mr. Morley states that it is a ‘South 
European species extending to Asia Minor, and is not yet 
known as British.’ ‘ In a wild state these parasites most often 
attack micros in pine cones and such like pabulum.’ 
ARACHNIDA COMMITTEE.—Mr. W. Falconer writes :—Lists 
of the Arachnida met with during the various meetings of the 
Naturalist,
