number being found therein. The only representative found of

For Entomology the Rev. Alfred Thornley, M.A., F.L.S., re- 

 ported that the day was cool but kept fine ; nevertheless, the great 

 rain of the day before had evidently driven away the insects, as the 

 number taken was far too low for such a magnificent district. 

 The best find, be thought, was the beautiful little Noctua, 

 Hydrelia uncula, which was not at all uncommon on the heath, 

 and several specimens were taken. Several young Kitten larvae 

 were taken on Salix repens which he thinks were D. furcula, but 

 he forgot to bring away a specimen. It was very interesting to 

 capture a specimen of the Wood Tiger {Nemeophila plantaginis) 

 so late as this, as it usually flies in May, but this only shows 

 once more how late the season is. Very few butterflies were 

 observed, and this was very disappointing, as the search for the 

 long-lost LyccBiia acis the day before at Epworth was rendered 

 abortive by the exceedingly wet weather. Only a single speci- 

 men of that very common Dragon Fly — Agrion puellct, was 

 observed in the pond ; it was a sore puzzle what had become of 

 the rest in so likely a locality for their occurrence. 



The beetles scarcely call for comment, and the same must be 

 said of the Diptera. The little and very pretty fly, Nemotelus 

 uliginosus, swarmed on Umbelliferae in the bog ; and one exam- 

 ple of Chrysotoxum bicinctum, a common fly hereabouts, w hich 

 mimics an Odynerus wasp, was taken. Several specimens oi the 

 robber fly, Dysmachus trigona, were seen and caught. But the
