The mosquito boiiipf an aquatic insect, tlio mito observed 

 by Mr. Sahnon nia}- be one of tln^ little water mites of 

 the family Hydrachnichc, but the nioscjuito issues frt)ni 

 its pupa so rapidly that this is hardly likely. It is more 

 likely to be one of the Trombidiida-, the youn*;- of which 

 ma.y crawl upon the mosquito when it is at rest upon the 

 plants. 



Some observations upon the natural enemies of the 

 malarial moscpiitoes of the <2:enus Anopheles have l)een 

 made by Dr. C \V. Daniels in East Africa (" lleports to 

 the Malaria Committe(> of tlu^ lloyal Society," Decendier 

 81, 11)00). He says that tish, and es[)ecially youn^- fry and 

 small fishes, will speedily destroy the mos(juito larva\ 

 but in spite of this. Anopheles larvfie are often found in 

 l)ools, rivers, etc., where fish are abundant, and pup.Te and 

 mature larvjie among" them. This is seen in open pools 

 as well as in the g-rass-grown rivers. He also says tli.it 

 tadpoles do not attack the larva^ even in captivity, and 

 g-oes on to say that larva' of (\)leo])tera and dragon-Hies, 

 oftrn found in numbers in water with abundant Ano])h- 

 eles larv.TB, even in cai)tivitv do not seem to devour them. 



In ponds where there are larcredeafed water-])lants. 

 mosquitoes frequently escape the attacks of fish, and 

 numy more of their natural enemies, by holding" to tlie 

 water-surface, es])(H'ially above partly subm(M\ued leaves. 

 This is es])ecially the case Avith Anopheles larva', which 

 remain (juite at the surface during the best part of their 

 existence
