Hemiptera (J. M. Brown, B.Sc.) : — Very little of special interest 
has been noted among the Hemiptera during the past season. Individuals 
seem to have been scarce, notwithstanding the sunny time during August, 
and the species taken have been mainly quite common ones. A visit 
to Allerthorpe Common during August was, unfortunately, spoiled by 
rain, but supplied a single specimen of Piezodorus lituratus F., a species 
reputed to be plentiful wherever gorse flourishes, but actually very local 
in the county, having been taken in two or three places only, and those 
chiefly on the coast. At the same time three species of Idiocerus were 
taken, viz. confusus Flor., lituratus Fall., and fulgidus Fab., this last
