 is well marked and the numerous smaller ones at its base are so well 

 divided that it is easy to see the connection between these and the

Culex viridiventer Giles. Genitalia, male. Basal clasp segment 

 very stout, broad, with a broadly rotmded apex. Terminal clasp 

 segment rather long, tapering gradually in a 

 double S-shaped curve to an acute apex. 

 This segment is remarkable because of the 

 series of irregular, coarse setae along the 

 middle of the ventral margin. Harpes stout, 

 terminated by a dense series of coarse, 

 chitinous spines, the outer ones blunt, the 

 inner acute. Harpagones rather slender, 

 tapering to an acute tip. Unci approximate, 

 tapering rapidly to an acute tip and remark- 

 able because of the series of stout, chitinous 

 teeth along the middle of the ventral 

 margin and the pair of stout teeth side by 

 side near the base. Setaceous lobes weakly 

 developed and bearing a series of fine, long, 

 curved setae. [Pi. 14, fig. i] 



This species presents remarkable features 

 in the serrations of the terminal clasp seg- 

 ment and the very pronounced ones on the 

 unci, reminding one somewhat of similar 

 structures occurring in Megarhinus. It might
