VI. — Economic Zoology. 



The work in connection with this Section has had reference 

 chiefly to insects, as in former years. The interest taken in 

 the spread of disease by insect agency remains, and numerous 

 biting flies have been sent for determination and advice. 

 Many insects injurious in other ways have also been sent to 

 be named. 



The following are some of the subjects of inquiry : — 



(1) Larvae of flies working under the skin of human 



beings in the Transvaal and causing sores. The 

 specimens sent were Cordylohia anthropophaga. 



(2) Inquiry respecting the life-history of Warble Flies, 



which the sender believed to have at least two 

 broods in the year.
