Animals which concern Man as causing bodily injury, some- 

 times death, to him, and in other cases disease, often of a 

 deadly character. 



Mosquito annoyance near Bristol. 



An insect, sent by Mr. W. B. IJoyce, of Bristol, that has caused 

 annoyance near that place for the last live years is a true Most|uito — 

 one of the Guliddm. It was the Cuhx diversiis (Theobald), so far only 

 recorded from Tunl»ridge Wells and Great Staughton (and recently 

 from Epping Forest). ( Vide p. 4.) 



Nothing is known of its life-history, but we may safely assume 

 that it is now about to deposit its eggs. The larvai will most likely 

 be found in small collections of water. These so-called " wrigglers " 

 should be searched for during the next few weeks, and all pools 

 found to contain them should be treated with paraffin to kill the 

 larvae. It may be pointed out that mosquitoes breed only in water, 

 and therefore cannot have been carried to the locality in the manuie 

 shipped to Avonmouth, as supposed. 



Swarms of Flies bred in House Refuse. 



An enquiry was sent to the Board, asking for information as to 

 how to destroy the swarms of flies that are breeding in the huge 

 masses of dust-bin refuse in certain London suburbs. 



" The annoyance caused in houses by flies which breed in huge 

 heaps of ' house ' and ' dust-bin ' refuse in certain of the suburbs of 

 London, referred to by Mr. Wain, may possibly be lessened, as he 

 suggests, by applying some soluble repellent. 



"Nothing has actually been recorded on this subject; but in the 

 case of the House Fly {Mitsca domrdlea), which breeds mainly in 

 horse manure, lime spread over the heaps of manure has stopped the 

 fly depositing its eggs.
