Culex pulcriventer Giles. Genitalia, male. Basal clasp seg- 

 ment enormously dilated, oval and with a peculiar internal patch 

 of long, halbertlike scales. Terminal clasp segment with the basal 

 portion somewhat enlarged, slender and 

 with a stout, curved apical spine. Harpes 

 very broadly dilated, excavated and 

 somewhat spoon-shaped. Harpagones 

 stout, curved, with an acute, recurved 

 apex. Unci slender, rounding gradually 

 to a rather acute apex. The setaceous 

 lobes appear to be represented by a ^- 

 pair of large, inflated organs densely /"^ 

 clothed exteriorly with numerous long, F-- i'ncUhiwin;;L'inilue^senVsof 



fine setae. [PL 14, ng. 2] teeth, much enlarged (Original) 



This species diverges widely from the normal type of Culex or 

 other allied American genera and it might well be referred to a new 

 genus. We refrain from erecting one because of our unfamiliarity 

 with the Indian fauna. 



Melaniconion atrata Theo. Genitalia, male. Basal clasp seg- 

 ment stout, tapering rapidly to a rather broad apex. Terminal 

 clasp segment rather stout, basal portion greatly enlarged, apical 

 portion slender and bearing a stout, subapical spine. Claspette 

 represented by a conspicuous subtriangular apical lobe and an inner 

 prominence bearing two stout, chitinous spines, the larger on a 

 well defined stalk. Harpes rather distant, stout, terminating in a 

 series of six or seven stout, chitinous spines. Harpagones rather 

 stout, ending in an acute point. Unci slender, approximate with a 

 broadly rounded apex. Setaceous lobes indeterminate. [PI. 15,

TAENIORHYNCHUS 



The study of male genitalia of the species at hand is not without 

 interest, particularly as the forms we have been able to secure, 

 appear to have considerable in common. One of the most striking 

 generic characteristics of this group, is the enormous straight, 

 ■^ickened, chitinous process terminating the claspette. Harpes 

 apparently absent. Harpagones with prominent apical teeth 

 varying in number from three to about five. The numerous fine 

 teeth along some portions of the margin of the unci, are another 

 feature apparently peculiar to this remarkable group of insects. 

 The setaceous lobes are fairly well developed and the seventh 

 segment bears submedian groups of stout chitinous spines. 



This genus presents some interesting diversities in the structure 

 of the male genitalia. The terminal clasp segments are normally 

 stout, curved, simple, but in the African species, Taenior- 

 hynchus aurites Theo., these organs are remarkable because 

 of the enormous, rounded, bladelike posterior lobe and the imique 

 compound hairs on its posterior border [pi. 16, fig. 2.] The
