550 A Monograph of Culicidae. 



Observations. — Described from a perfect £ , partly dissected. 

 It cannot be placed in any known Aedlne genus, so a new genus 

 has been made for it. The abdomen is very long and thin, but 

 whether this character will occur also in the <j? remains to be 

 seen. 



The type is in the National Museum of Hungary, Budapest. 



Genus HAEMAGOGUS. Williston. 



The genus Haemagogus is now divided into three genera, 

 Haemagogus, Williston (Sen. St.) ; Gualteria, Lutz, and Cacomtfia, 

 Coquillett. 



Gualteria is easily told by the curious apical expansion of the 

 last few segments ventrally, and Cacomyia by the abdomen of the 

 $ having a large cluster of outstanding blunt spines on the 

 under side of the penultimate segment. 



Dr. Lutz places these in a separate sub-family Haemagoginae.
