Of the genera noted above some are more important than 

 others, both as regards the number of species and their relation 

 to disease transmission. 



Mucidus (seven species). The larvae are predaceous and, like those of the 

 MegarhininiB, feed on other mosquito larvas. Species of Mucidtia have a 

 very striking " mouldy " appearance, due to the long outstanding scales 

 on the legs, etc. Not one of the species has been noted as concerned in 

 the transmission of disease. 



Banksinella (five species). Some species at least suck human blood with 

 avidity. No species has been proved to transmit any disease. 



Stegomyid and Kingia (over 40 species). Mosquitoes of the genus Stegomyia 

 are medium-sized, brilliantly banded and marked with black and silvery 

 white. The head is entirely covered with fiat appressed scales and all 

 lobes of the scutellum likewise carry broad flat scales. 



The following is Theobald's table for the differentiation of 

 the species of Stegomyia, with some additional ones described 

 since his work was published.
