Genus Trichoprosopon . 
557 
Trichoprosopon nivipes. Theobald (1901). 
Joblotici nivipes. Blanchard—Theobald. 
Mono. Cnlicid. II., 285 (1901); III., 584 (1903) ; IV., 593 (1907); 
Culicideos do Brazil, 271 (1908), Peryassu. 
Brazil, Mexico, Trinidad, Costa Rica, and Salvador. 
Prof. Goeldi has described and figured the larvae from Brazil. 
He found them in the water in the leaves of bromelias, in the 
axils of banana leaves and in holes in fallen trees. The species is 
distributed throughout the moist tropics. Mr. Busck collected 
larvae in Trinidad from cacao husks, and Mr. Knab found them 
in cocoanut shells and cacao husks at Puntarenas, Costa Rica, 
and Sonsonate and Xzalco, Salvador. The water in which they 
occur is very dirty, of a thick consistency. The eggs are laid 
in rafts, erect as in Gulex , but of circular outline, not elliptical. 
Type in the British Museum. 
Trichoprosopon compressum. Lutz (in Theobald) (1907). 
Mono. Culicid. IV., 590 (1907), Theobald ; Culicideos do Brazil, 
274 (1908), Peryassu. 
Brazil. 
Trichoprosopon lunata. Theobald (1901). 
Joblotia lunata. Theobald (1901). 
Wyeomyia lunata. Theobald (1901). 
Lesticocampa lunata. Dyar and Knab. 
Mono. Culicid. II., 279 (1901); III., 336 (1903); IV., 594 (1907); 
Culicideos do Brazil, 276 (1908), Peryassu. 
Brazil. 
Type in the British Museum. 
Note. —If Dyar and Knab are right in their identification, 
they place this in a new genus founded on larval characters. 
The larvae came from Trinidad. 
Note. —The genus Lesticocampa founded by Dyar and Knab 
on purely larval characters, seems to me invalid; they founded it 
on the supposed larvae of lunata , Theobald, taken in bromelia 
water at Arima, Trinidad. A re-examination of this insect 
shows it has a hairy clypeus and comes well in Trichoprosopon .* 
Further notes are added in the Appendix on Lesticocampa.
