252 F, W. EDWARDS—THE AFRICAN 
seems probable that Dyar’s Coquilletiidia is not properly separable from 
Taeniorhynchus. The type species of the genus Chrysoconops, C. fulvus, 
Wied., has no connection with the African and Oriental species associated 
with it since the genus was founded; it does indeed resemble them in 
colour, but in structure it is nearer to Ochlerotatus than to T'aeniorhynchus. 
In the present writer’s opinion Culex titillans, Wlk., must be taken 
as the type of Arribalzaga’s genus, because it is quite evidently the 
species which he describes, although he wrongly determined it as 
C. taeniorhynchus, Wied. On this view, which is the reverse of that held by 
Dyar and Knab, Mansonia becomes a synonym of Taeniorhynchus since 
C, titillans was also the type of Mansonia. 
If C. taeniorhynchus, Wied., be taken as the type, Arribalzaga’s careful and 
complete description of Taeniorhynchus becomes inaccurate in many important 
particulars ; this course, if adopted, would necessitate sinking Culicelsa, Felt, as 
a synonym of Taeniorhynchus, and produce the anomaly of a genus none of 
whose members possessed the generic characters.

Somewhat variable, some specimens showing dark apical patches on some of
