ENTOMOLOGICAL SECTION. 



Neuroptera and Trichoptera. — Mr. G. T. Porritt writes : — 

 In Neuroptera, perhaps the most interesting item was the 

 re-discovery by Mr. H. H. Corbett of the dragon-fly, Libelltila 

 fulva in its old locality, Askern, at the end of May. The 

 specimen was immature, and the date early, and it was un- 

 fortunate that no expedition was made a little later to ascertain 

 whether the species was there in numbers. The local Hemerobius 

 orotypus was common to Mr. J. W. Carter and myself in the 

 Grass Wood at Grassington in September ; and on the river at 

 the same place, a few days previously, Mr. Carter found Leuctra 

 geniculata and Halesus auricollis commonly. In June Mr. L. S. 

 Brady and I took the formerly very rare trichopteron Stenophylax 

 alpestris in abundance near Sheffield. At Glaisdale, early in June, 

 I found Ecclisopteryx guttulata and Leptocents nigro-nervostis in 

 abundance in the River Esk, where also Lasiocephala hasalis and 

 Brachycentrus suhnubilus occurred in smaller numbers, but 

 commonly. Mr. T. A. Lofthouse has given mc Leptocerus hilinea- 

 tus from near Middlesbrough. 



Lepidoptera. — The secretaries report that without doubt 

 the past season has been a disappointing one to lepidopterists. 

 Only seven persons have felt they had anything at all worth 

 reporting, out of fifty-one entomologists in different parts of the 

 county who were written to on the matter. 



From our own observations and from the few letters which 

 have been received, we should not feel justified in attributing the 

 bad results of collecting to any scarcity of insect life, but rather 

 to climatic conditions which have " damped " the ardour of even 

 the most enthusiastic, and made some modes of collecting almost 

 impossible, and others unproductive. 



Warm sunshine during May caused the Aphides to get a good 

 footing earlier than usual, and as a result, honey-dew has been
