INSECUTOR INSCITI.^ MENSTRUUS 171 



In respect to the larvae, abominator is identical with erraticus 

 and agitator with floridanus, though, through minor errors, 

 we placed them separately in the tables. 



Other corrections apply to abominator, egberti, and niastigia, 

 which were described as possessing white abdominal bands. 

 In abominator and egberti these consist of white central spots 

 with a few scattered scales, and should be described as dotted; 

 in mastigia the appearance of bands is illusory in the female, 

 being due to the visibility of the pale integument and the pale 

 bristles, and vanishes under sufficient magnification. The male 

 in this species has distinct abdominal bands. Again egberti 

 and mastigia are separated on the deceptive character of the 

 white eye-margin, referred to above, which we would discard 

 as unreliable. 



This is a rather formidable series of mistakes in so small 

 a group of species and naturally involves some changes in 

 synonymy. We believe that the species are here placed on 

 reliable characters. 



The genus Culex as a whole, as it occurs in the United 

 States, may be divided into subgenera on the characters 

 afforded by the male genitalia. From this standpoint, Dein- 

 ocerites represents only a section of Culex, while, on the 

 other hand, Culicella and Climacura are plainly distinct 

 genera, the former nearer to Culiseta than to Culex. We 

 include them all in the following review:
