336 Appendix.

brown bands and brown plume-hairs. 
Thorax as in the 9 1 abdomen narrow, ornamented as in 
the 9 • Legs unbanded, traces of a pale knee spot; fore and 
mid ungues unequal, the larger one uniserrated, the smaller (?); 
hind ungues small, equal. 
Length. —4 • 5 mm. 
Habitat. —Bonny (Annett). 
Time of capture.— May. 
Observations. —Described from a single $ and 9 taken by 
Dr. Annett and in his collection. 
The abdominal banding of the seventh and eighth segments 
expanding laterally serves as a good means of identifying it at a 
glance. 
11. Culex humilis. n. sp. (Lutz MS.).

distinct genus.
