Female. Lobes about four times as long as broad, tapering 

 abruptly beyond the middle. Apex rounded, with a few some- 

 what stout hairs. Ventral plate about two thirds the width of a 

 lobe, deeply emarginate apically. 



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

 ment stout, slightly tapering and rounded apically and with a 

 small apical lobe. Terminal segment rather slender, curved, and 

 with a slender, long, apical spine. Claspette a conspicuous, setace- 

 ous lobe at the basal third^ Harpes with basal portion stout, 

 slightly enlarged at distal third, where there are several stout, 

 internal spines; apical portion slender, tapering gradually to a 

 rounded point and strongly bent outwardly at the basal fourth. 

 Harpagones stout, strongly curved and ending in a stout, recurved 

 spine. Unci broad, approximate, rounded apically. Setaceous 

 lobes approximate, moderate in size and bearing about eight stout, 

 chitinous spines. 



Female. Lobes rather stout, nearly five times as long as broad, 

 gently rounded exteriorly to a somewhat acute point. Apex with 

 a number of somewhat stout hairs. Ventral plate as wide as a 

 lobe, extending to basal third and slightly emarginate apically. 



Culicada subcantans n. sp. Genitalia, male. Basal clasp seg- 

 ment stout, sides nearly parallel, tapering somewhat distally and 

 with a well developed distal lobe. Terminal segment slender, 

 slightly swollen near the middle and with a long, slender, apical 

 spine. Claspette a slight basal lobe bearing a very long curved, 

 chitinous spine and a few large setae. Harpes with the proximal 

 portion stout, and at the basal third several large, internal spines; 

 distal portion a very long, slender, halbert-like blade, with a 

 slightly recurved, acute tip. Harpagones evenly rounded, termi- 

 nating in a stout, recurved tooth and with several smaller teeth. 

 Unci approximate, rather broad, apex acute. Setaceous lobes 

 well developed and bearing numerous large, chitinous spines. lPI. 7,

Female. Lobes stout, about four times as long as broad, gently 

 rovinded exteriorly to a rather broadly rounded apex bearing a 

 number of stout setae. Ventral plate as broad as a lobe, extending 

 slightly beyond the basal third; apically, strongly emarginate and 

 with a slightly sinuate lateral margin. 



Culicada cantans Meig. Genitalia, male. Basal clasp segment 

 rather stout, slightly broader apically and distinctly lobed. Basal 

 portion with a conspicuous triangular internal lobe on the ventral 

 margin. This is clothed with coarse setae and tipped with a brush 

 of long hairs, those from the lobe of one side intermingling with 

 those from the lobe on the other. A pair of very characteristic 

 long setae arises from just before the apex of the basal segment. 

 Terminal segment slender, slightly curved, swollen near the middle 

 and bearing a long, slender, rather stout apical spine. Claspette 

 represented by a dark, triangular elevation at the base of the tri- 

 angular lobe described above. A stout, curved spine arises at its 

 larger lateral end and many smaller fine setae spring from along
