SCIENTIFIC NOTES AND OBSERVATIONS. 



Hibernation of Vespa vulgaris. — Having a warm corner in my 

 heart for the British Vcspidae I was particularlj' interested in Miss 

 Fison's note on p. 87 under the above heading. It is not a rare thing 

 I believe to find queen wasps hibernating behind pictures, but they 

 are usually attached to the /nctnn', not to the iiall. It is not clear 

 how the thread referred to secured the wasp to the wall ; if it were in 

 the form of a loop over the thorax or abdomen in the manner of the 

 thread in the case of the pupa) of Pierid and other butterflies, then 

 I should think it was spun by a spider after the wasp had become 

 thoroughly torpid. Since queen wasps fold up their legs and wings 

 beneath the abdomen and thorax and cling to the support only by 

 their jaws, the specimen in question must have gripped a small 

 irregularity in the plaster of the wall by that means, or possibly, a
