250 THE MOSQUITOES. 



Grabhamia. Wings have pepper-and-salt appearance with short 

 fork cells. 



Tceniorhynchus. This genus is characterized by dense wing 

 scales, which are broadly elongated with truncated apex. 



Acartomyia. Much like Grabhamia, but scales of head give ragged 

 appearance. A. zammittii was supposed to be concerned in Malta 

 fever (not proven).
