(B.G. Med. Aun. 1905, p.p. 23, 38. 1906, p.77. 1908, p. 25.) 
Genus TricHoprosopon, Theobald. 
In this genus Theobald seems to include Joblotia (Blanchard) renee 
his synoptic table appears to distinguish them. (M. Cul., Vol. 
p. 554.) The Genus Joblotia was formed from lunata by Lutz on ae 
absence of hairs on the clypeus, but is replaced by Theobald in Tri- 
choprosopon in his Vol. V, (v. p. 557); the note in that reference is 
contradicted by his note on Lesticocampa id,, p. 621, which replaces 
lunata in Joblotia!! A Joblotia sp. was identified amongst specimens 
collected at Yupukari, and sent by Dr. Wise to the London School of 
Medicine. I have not seen a description of the species which was 
reported to be new. (v. B. G. Med. Annual, 1908, p. 4. 
Genus GoELDIA. Theobald. 
One species found by Dr. Low on the Demerara river and by Dr. Lutz 
in Brazil is the sote representative of the Genus. 
Goeldia fluviatilis, Theobald.
