sent me the specimens. M. Simond bred his specimens from 
larvae found in a tin of water discovered in the woods of the 
coast mountain-range near Rio. Dr. Lutz also sent a 9. The 
difference between the ¢ and 9 proboscis is very marked. The 
specimen I have mounted in balsam shows the genitalia, but not 
sufficiently well to make out in detail. Iam also not quite sure 
of the fore ungues, as the legs in the specimen have become 
entangled. 

Sup-ramity JOBLOTINA.* 
Genus 48. JOBLOTIA. Blanchard. 
Trichoprosopon. Theobald.

Blanchard; Mono. Culicid. IT., p. 283, 1901 (Trichoprosopon), Theobald. 
No new species has occurred in this genus, but a species I 
had previously placed in the genus Wycomyia—viz., W. lunata— 
belongs here. The name T’richoproscpon, I described this genus 
under, having been previously used, Prof. Blanchard renamed it 
Joblotia. — 
JOBLOTIA NIVIPES. Theobald. 
Trichoprosopon nivipes. Theobald. 
(Mono. Culicid. II., p. 285, 1901.) 
_ Additional localities —Rio de Janeiro and Sao Paulo (Dr. 
Lutz). 
Notes on the Life-history. 
The eggs are laid singly in small numbers on the surface of 
the water; the rather large larva escapes the next day. Dr. 
Lutz has bred out the 2 imago in about five weeks. 
Some larvae were found in a water bucket at Manaos, on the 
Amazon, and formed the food for Megarhinus larvae. Dr. Lutz 
says they are generally bromelia feeders, but probably lay in 
any water near woods. 
Larva of Joblotia nivipes. 
A single larva has been sent me in an immature state. It 
is rather transparent and the specimen somewhat shrunken ; 
* This sub-family and the following one should come before the 
sub-family Aedeomyina, p. 275.
