outer side on the basal half a tuft of a few fine hairs; thorax 
broader than the head, with lateral tufts of plumose bristles arising

fifteen in number, and two ventral rows of ten near the base of the 
siphon, numerous short spines at the base of the last segment, the 
apical segment with dorsal and ventral hair tufts ; in the adult 
larva there are also stiff spines at the base of the siphon on the 
segment, two prominent tufts of hairs on each side at its base, 
and a small one on the side about the middle of the siphon. 
Length,—8 rm. 
The pupa with rather short siphons, with truncated openings ;

Genus 26. TAENIORHYNCHUS. Arribalzaga. 
(Mono. Gulicid. IL., p. 190, 1901.) 
Several new species are added to this genus. There is some 
variation in the structure of the palpi. 
Professor Goeldi has observed the eggs of T. fasciolatus. 
They are laid in curved rows close together, and are shaped like 
champagne bottles, and have the air chambers spread over their 
whole surface. The larvae have very long antennae. Full notes 
on these will be published by Professor Goeldi. 
TAENIORHYNCHUS FULVUS. Wiedemann. 
Culex fulvus. Wiedemann. 
Culex flavicosta. Walker. 
(Mono. Culicid. II., p. 208, 1901.) 
(Plate XII.) 
A fresh series of this species has been received from Pro- 
fessor Goeldi, of Para; from these some additional notes 
are appended, as I have been able to dissect some of the 
specimens.
