70 INSECUTOR INSCITI^ MENSTRUUS 



a short arm, bearing a long filament with hooked tip and a 

 small filament ; middle filament distinct, blade-shaped, approxi- 

 mated to the outer group of filaments, which consist of a small 

 filament, a broad one with spatulately expanded tip, and a 

 rather small leaf, the latter elliptical, pointed, and arising from 

 a very large insertion. Inner division of the lobe of side-piece 

 with both arms short, the inner shorter, well separated, each 

 with a long curved filament with enlarged pointed tip. Second 

 uncal plate furcate, both limbs pointed, a stout horn near the 

 tip. Articulated plate broadly expanded, the outer margin 

 rounded, with a point on one corner. Basal hooks long, re- 

 curved, pointed at tip. Basal appendages large, elliptical, ob- 

 lique, with many small setse. 

 From Santo Domingo. 



Culex (Choeroporpa) comminutor, new species. 



Clasp-filament rather narrowly snout-shaped, the spine ap- 

 pendiculate. Outer division of lobe of side-piece slenderly 

 columnar, with a short inner arm, bearing a long filament with 

 hooked tip and a short blade-shaped one ; middle filament 

 blade-shaped, and a little basad of its insertion is a triangularly 

 expanded leaf, not as long as the filaments ; two blade-like fila- 

 ments and one round-tipped one on the outer aspect of the 

 lobe. Inner division of lobe of side-piece with the arms well 

 separated, the outer rather long, the inner short, each bearing 

 a stout filament with widened pointed tip. Second uncal plate 

 with long slender stem, the tip furcate, inner arm horn-like, 

 outer with bluntly triangular point ; below the middle of the 

 stem, a very large horn -like spine. Articulated plate small, tri- 

 angularly widened. Basal hooks long, recurved, but rather 

 stout, the points in the mount, only reaching back to the origin. 

 Basal appendages of good size, but triangularly expanded and 

 tubercular as if in process of reduction ; setse numerous, small. 



Adult with mesonotum bronzy brown scaled, the abdomen 

 with white basal segmental bands. Wing-scales rather broadly 

 ovate. Legs bronzy black.
