VI. — Economic Entomology. 



The work of the Department in Economic Entomology has been 

 carried on by members of the staft" with the assistance of Mr. C. A. 

 Ealand, whose services as a specialist in that branch were again 

 engaged during the year. 



Further large accessions of material presented for the most part 

 by the Imperial Bureau of Entomology, have been incorporated in

 more than ordinary economic importance, such as the Aphidse and 

 Coccidse amongst the Rhynchota, and the Bruchidge amongst the 

 Coleoptera, have received special attention, and have made a fair 

 amount of progress. 



As a result o£ a correspondence in the Press on the question of 

 hibernation of the common house-fly (Musca domestical large numbers 

 of flies found in houses in various parts of the United Kingdom 

 during the first three months of the year were received at the 

 Museum. These flies have all been examined and identified, and it 

 has been found that in the consignments from more than 160 

 different persons, the common house-fly was present in only 18, 

 the total number of specimens of this species (^M. domestica) received 

 being 32, most of which had been captured in kitchens or other 

 warm rooms, and while in a more or less active condition. The 

 evidence thus obtained gave no support whatever to the idea that 

 the common house-fly passes through the winter as a rule in the 

 adult stage. In contrast with the very small proportion of true
