Culicada trichurus Dyar. Genitalia, male. Basal clasp seg- 

 ment stout, arcuate, with distinct terminal lobes. Distal segment 

 rather slender, slightly swollen, at basal third, curved, and with a 

 long, rather stout, terminal spine. Claspette a distinct, basal, 

 triangular, setaceous lobe bearing several very long, stout 

 spines. Harpes with basal portion strongly curved, thickly set- 

 aceous; apical part smooth, very irregular, apparently convoluted 

 apically and terminated by a very long, slender spine. Harpagones 

 stout, curved, with a strong, recurved spine. Unci slender, some- 

 what separated and tapering, with the apex oblique, serrate, and 

 the acute tip with a prominent tooth. Setaceous lobes well de- 

 veloped, widely separated and bearing numerous stout, chitinous 

 spines. 



Female. Lobes a little over three times as long as broad, curving 

 on both sides to the somewhat broadly rounded apex bearing a few 

 stout setae. Ventral plate a little broader than a lobe, reaching 

 about to the middle, very slightly emarginate apically. This organ 

 has a somewhat characteristic series of transverse rows of moderately 

 stout setae besides the larger apical and subapical ones observed in 

 most species. 



Culicada impiger Walk. Genitalia, male. Basal clasp segment 

 stout, slightly curved, with a distinct apical lobe. Terminal seg- 

 ment rather stout, slightly swollen at basal third and with a long, 

 rather stout apical spine. Claspette a basal, internal lobe bearing 

 a pair of long, stout, curved spines. Harpes with basal portion 

 stout, setose, with two large, internal spines and a larger, terminal 

 one; terminal portion subapical, smooth, basal part simple, bearing 

 a terminal, falcate structure with an acute, recurved tip. Harpa- 

 gones stout, curved, with a strong, recurved hook, also conspicuous 

 internal setae. Unci contiguous and broad at base, apical portion 

 distant, obliquely rounded and terminated by an acute spine. 

 Setaceous lobes medium, bearing numerous stout, acute spines. 



Female. Lobes a little over three times as long as broad, tapering 

 or curving gradually from near the base to the rather broadly 

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

 lobe, extending to the basal third and deeply emarginate apically. 



Culicada lazarensis Felt & Young. Genitalia, male. Basal clasp 

 segment stout, slightly curved and with a distinct apical lobe. 

 Terminal segment slender, curved, and with a stout, long apical 

 spine. Claspette a conspicuous basal lobe bearing numerous small 

 setae. Harpes, basal portion setaceous, with several stout, internal 

 spines at basal third; apical part simple and bearing a rather 

 broad, nearly straight, falcate blade with an external recurved hook. 

 Harpagones stout, curved, and with a strong, recurved hook. Unci 

 approximate, broad at base and tapering apically to widely sepa- 

 rated, rounded tips. Setaceous lobes large, well separated and bear- 

 ing numerous strong spines. 



Culicada puUatus Coq. Genitalia, male. Basal clasp segment 

 slightly curved, with strongly developed apical lobe. Terminal 

 segment rather stout, slightly swollen at the basal third and with a
