PSYCHE 
[Februarj- 
1906). The correspondence of Anopheles and Ciilex (in the re.stricted sense) in claw 
structure does not indicate a closer relationship between these genera than with such 
forms as Aedes. Nor does the marked difference in the claw structure of Janthino- 
soma and Feltidia disprove the close relationship of these forms indicated by their 
•SO closely similar larva and male genitalia. While the presence or absence of teeth on 
the claws may be used with advantage in the definition of minor groups, if used as a 
])rimarv character it would result in quite arbitrary combinations. Indeed there 
is reason to doubt if it should be considered of even generic value. 
Since the publication of my article on the swarming of Culex pipiens the follow- 
ing additional references to the copulation and swarming of Culicidae or Chiron- 
omidae have come to my notice.
