A Monograph of Culioidae. 
Genus 13.— TAENIORHYNCHUS. ArHbalzaga. 
(Modified, F. Y. T.) 
(Dipt. Argentina, p. 47 (1899).) 
Palpi long in the $, short in the 9 1 the fifth joint in the 9 
minute, buried in scales; $ palpi longer than the proboscis, 
third joint long; head clothed with narrow curved scales and 
upright forked ones; thorax and scutellum with narrow curved 
scales ; abdomen with flat scales ; wings clothed with thick elongated 
scales , ending either diagonally and convexly , cr more or less bluntly 
pointed (Plate E, and Fig. 245), median linear scales to the veins 
often absent; legs usually spotted or banded ; ungues of female 
equal and simple, of the male unequal in the 
fore and mid legs, the larger one with one or 
two teeth, the smaller simple, the hind claws 
also simple ; wings with similar venation to Culex. 
The proboscis is usually banded. 
I have retained one of Arribalzaga’s species 
in his genus Taeniorhynchus , but have modified 
the characters of the genus, the essential 
character being the form of the wing scales, as 
seen in his T. fasciolatus , which is quite distinct 
from his T. taeniorhynchus, the C. titillans of 
Walker. Ficalbi’s Culex Bichardii comes in this 
Wing scales of genus, in spite of the male ungues differing 
Taeniorhynchus. 
from those of Arnbalzaga s species. 
Walker’s Culex perturbans also comes in this genus, and 
numerous other species mentioned in the following pages. 
They all seem to be sylvan insects, and can at once be told by 
the densely scaled wings, the scales being comparatively thick. 
Nothing is known regarding the ova, larvae, or pupae of any 
species in this genus. There are two main groups in the genus, 
(i) brown species, (ii) yellow, metallic purple and orange species.
