Fig. 15 Culex concolor, a portion of the harpes and 

 harpago with the peculiar basal, chitinous 

 processes, much enlarged (Original) 



nearly right angles. Harpagones enlarged at base, strongly angu- 

 late near the middle and with one very large_ stout, chitinous spine 



and numerous minor 

 ones. These latter 

 appear much like 

 long, fused, chitinous 

 processes. Unci slen- 

 der, tapering to a 

 broadly rounded 

 apex. Setaceous 

 lobes indeterminate 

 in the preparation . 



This species is close- 

 ly allied to C. t i g r i - 

 pes Grand., both 

 presenting a most in- 

 teresting stage, show- 

 ing the partial divi- 

 sion of the harpagones. In these two species the main chitinous spur 

 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 

 same spurs more strongly developed in such species as C . a n n u - 

 1 i r o s t r i s Skuse, 



Culex viridiventer Giles. Genitalia, male. Basal dasp segment 

 very stout, broad, with a broadly rounded 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 

 well be referred to a new genus and we 

 'iiarged refrain from erecting one because af our 

 unfamiliarity with the Indian faima.
