170 A Monograph of Culicidae. 



Miss Ludlow placed it in the genus Stegomyia, but the presence 

 of flat scales on the mesonotum at once precludes it from that 

 genus. It evidently comes in the genus Quasistegomyia. 

 Although I have not seen perfect specimens (those sent me by 

 Miss Ludlow being much denuded) there is no doubt, from her 

 full and able description, that it comes in this genus.

Nineteen species of true Stegomyia are now known. 



The genus is entirely restricted to those species in which the 

 head and scutellum are entirely clothed with flat scales. Thus 

 several species previously provisionally included in this genus 

 have been excluded. 



The genus Desvoidya comes somewhere near Stegomyia, but 

 differs in the male palpi, genitalia and general appearance to a 

 marked degree, and the larvae also are very different. They 

 certainly cannot be included in Stegomyia, as Giles would have 

 done, for they are as different structurally from that genus as 

 Stegomyia is from Culex.
