house-flies received, was the great preponderance of Pollenia rudis, 

 a species known as the cluster-fly. This species was present in 103 

 out of the 160 consignments, and the specimens received, although 

 stated in most cases to be only a few samples of the kinds found, 

 reached to some thousands in number. In several houses, the 

 cluster-fly was hibernating in such vast numbers as to become a 

 serious nuisance, and many requests for information on the best 

 means of getting rid of them were received. Next in point of 

 numbers to the cluster-flies, and frequently associated with them 

 in the same hibernating swarms, were the two species, Limnophora 

 septemnotata and Musca autumnalis. Flies found hibernating under 

 the roofs of churches were found in a few cases to consist chiefly of 

 the latter species.
