in Yorkshire until a few years ago — has been taken fairly plenti- 

 fully, my friend and I having- handled at least sixty specimens, 

 which have been procured either singly or in small numbers. 

 I have never yet been fortunate enough to find a large colony 

 of any kind, the most I have "yet seen together being just over 

 twenty Noctules, and these were on the point of leaving the hole 

 in which they had spent the winter when I was attracted by their 

 cries and discovered their hiding-place in a large beech tree. 



Always rather difficult of observation, and looked upon by 

 most people as very mysterious creatures indeed, Bats are most 

 interesting animals to study, either in a state of nature or in 

 captivity. A Long-eared Bat which I have kept some months 

 shows no signs of sleeping during the winter, but every night 

 runs nimbly over the gauze around his cage and awaits the time 

 for feeding. He will eat flies, moths, pupa and beef cut very 

 small, but mealworms constitute his staple food, and upon them 

 he chiefly subsists. What the capacity of his stomach may be 

 I cannot tell, but he is certainly possessed of a good stomach 

 and a good appetite, as the devouring of twenty mealworms in a 

 short time is apparently very little trouble, after which he will 

 fly swiftly round the room, occasionally resting and cleaning 

 himself, and on the whole gives one the impression that he has 

 spent a most enjoyable night. 



LEPIDOPTERA, 



Hadena adusta in Middlesbrough. —When sugaring in 

 Kensington Road, on 4th July last, I obtained a fine female of 

 this moth which had only once before been noticed in Cleveland, 

 at Kildale. It laid eggs, which have been successfully reared 

 to the pupa state. — Frank Elgee, Middlesbrough. 



COLBOPTERA. 



liylesinus crinatus in West Yorkshire. — While searching 

 in the neighbourhood of Cawthorne, near Barnsley, recently, 

 I came across an old ash tree swarming with this beetle. The 

 tree is dead, and, I have no doubt, that }ears ago the beetles 

 hastened its death. Since then I have found several trees near 

 Keighley destroyed by the same beetle. I am not aware that 

 this beetle has previously been recorded from W^est Yorkshire.
