sharp tips. Basal appendages small, separate, trigonate, with 

 about 15 short setae arising from conspicuous tubercles. 

 From Panama. I still have only the unique type.

Clasp-filament mediumly broad, snout-shaped, the spine 

 widened and appendiculate. Outer division of the lobe of side- 

 piece columnar, rather short, the inner angle scarcely produced, 

 bearing a long hooked filament and a shorter blade-shaped one ; 

 middle filament broadly blade-shaped, large ; of the outer group 

 of filaments, one has a very large insertion as if to support a 

 leaf, but I cannot see that such a structure is present, the fila- 

 ment arising from this insertion seems stout, but about the 

 length of the other outer ones. Inner division of lobe of side- 

 piece with the arms separated, the outer not over twice as long 

 as the inner, which is a little longer than broad. Second uncal 

 plate badly distorted in the mount, apparently furcate, one limb 

 pointed, the other smooth, with a small horn at the fork. 

 Basal hooks long, recurved, flattened, but with pointed tips. 

 Basal appendages rather large, oblique, elliptical, with rather 

 long fine setae, about 30 in number. 



From Santo Domingo. 



Culex (Choeroporpa) jonistes, new species. 



Clasp-filament very broadly snout-shaped, the spine appen- 

 diculate. Outer division of the lobe of side-piece columnar, 

 the inner filament arising near the base and lying along the 

 column, hooked at tip ; short accompanying filament inserted 

 toward apex of column, blade-like; middle filament inserted 

 near the tip of the column, the three outer ones on the summit, 

 which curves outward a little. Inner division of lobe of side- 

 piece single, the inner filament inserted a little basally of the
