segment rather slender, strongly curved at the apical third and bear- 

 ing a long, slightly curved apical spine. Claspette an inconspic- 

 uous tubercular setose basal enlargement with a stout, chitinous 

 spine at its ventral margin. There is also a large, setaceous sub- 

 apical lobe on the ventral segment. Harpes quite long, the setose 

 basal portion extending to the middle of the basal clasp segment; 

 apical portion smooth, bladelike and usually with a pronounced 

 angle on its posterior "edge. Harpagones stout, curved and termi- 

 nating in a stout, recurved, chitinous spine. Unci fused, expanded 

 anteriorly, gently tapering posteriorly to obliquely rounded dentate 

 apexes separated by a broadly excavated space. Setaceous lobes 

 well developed and bearing six or seven stout, chitinous spines. 



The structure of these organs appears to be somewhat variable 

 in this species, this being particularly true of the claspette, which 

 appears to be rudimentary in .some individuals and also of the 

 terminal portion of the harpes, which is apparently quite variable 

 in length. [PI. 9, fig. i] 



Female. Lobes scarcely four times as long as broad, wider at 

 the basal third and rotmding gently therefrom to the somewhat 

 acute apex bearing a few stout setae. Ventral plate as wide as a 

 lobe, deeply emarginate apically and with a sinuate lateral margin. 



Culicada annulifera Lud. Genitalia, male. Basal clasp seg- 

 ment moderateh^ stout, gently curved with broadly rounded apex. 

 Terminal clasp segment slender, gradually curving at the apical 

 third to a long, rather stout terminal spine. Claspette a conspic- 

 uous tuberculate basal lobe bearing numerous stout setae. There 

 are also two stout subapical setae internally. Harpes slender, 

 basal portion setaceous, apical naked, slender and tapering to an 

 extremely acute tip. Harpagones stout, slightly expanded at the 

 apex and with an almost recurved, acute apical spine. Unci 

 slender, approximate, tapering to an acute apex. Setaceous lobes 

 well produced, with five or six stout apical spines. 



Culicada confirmatus Theo. Genitalia, male. Basal clasp seg- 

 ment stout; long, with a broadly rounded apex. Terminal clasp 

 segment rather stout, slightly swollen near the middle and with 

 a long, stout terminal spine. Claspette an inconspicuous basal 

 setaceous lobe bearing a very large, chitinous spine somewhat 

 swollen near the base and tapering gradually to a very fine, recurved 

 point. Harpes with basal portion setose, slender, apical part 

 smooth, falcate and with a slight, recurved, blunt tip. Harpagones 

 stout, curved and with a strongly recurved, acute tip. Setaceous 

 lobes well developed, each with about eight stout, chitinous spines. 

 Unci slender, approximate, rounding gradually to an acute apex.

Culicada cantator Coq. Genitalia, male. Basal clasp segment 

 stout, rather long, with conspicuous apical lobe. Terminal seg- 

 ment slender, curved, and with a long, rather stout apical spine. 

 Claspette a rather conspicuous, basal, setaceous lobe bearing one 

 very long, stout, recurved spine, a shorter and numerous smaller 

 ones. Harpes with basal portion rather stout, setaceous, a few
