scales, and its extremely short female palpi, are distinctive. As I have

O'Reili.ia, nov. gen. 



Head clothed with curved, forked, and flat scales, much as in Culex; 

 scutellar scales flat; wing scales usually symmetrical, very broadly truncate, 

 and notched; palpi extremely short in the female. 



The genus is named after Gen'l Robert M. O'Reilly, Surgeon-General, 

 U.S.A., whose broad interest in all scientific study in any way connected 

 with Medical work has made possible many researches, and among them 

 the continuance of this mosquito work.

 are white; a couple of bristles between the eyes: white rim around the 

 eyes ; white flat lateral scales ; antennas dark, verticels and pubescence 

 light, basal joint testaceous with a few small, white, flat scales; palpi
