It will be seen that Lutz bases his primary divisions on 
larval characters, which is not allowable in a table for adults. 
The Anophelinae should be separated on some adult character. 
The palpal character heretofore used is weak; but some other 
may be found, perhaps in the very long slender legs, or elongate 
thorax. The Megarhininae are separated by Lutz on the 
curvature of the proboscis, which will not hold. By Theobald, 
the venation is used ; but the character seems to me a weak one, 
as it consists in the relative degree of stalking of two pairs 
of veins only. I am inclined to throw the Megarhininae in with 
the Culicinae, where they fall near to Psorophora and Lutzia, 
the larvae of these three genera being exclusively predaceous. 
The really strong character in Lutz's table is the presence or 
absence of setae on the metanotum; the scales do not count. 
I think, and am supported by larval characters, that the 
rest of Lutz's subdivisions, based on the palpi, are weak and 
should be dropped. We have really only three subfamilies 
of the Culicidae, definable on sound characters both as adults 
and larvae. 
i. ANOPHELIN^B. Adults 1 : metanotum nude; palpi long in 
both sexes. Larvae with sessile air tube; dorsal fan-tufts for 
attachment to the water film. 
Genera. Anopheles, Cellia, Cycloleppteron, etc. 
n. CULICIN^. Adults: metanotum nude ; palpi only rarely 
long in the female, usually long in the male, occasionally short 
in both sexes. Larvae with an elongate air tube; no fan-tufts 
for attachment to the water film ; anal segment with a ventral 
brush or rudder. 
Genera. Megarhinus, Psorophora, Lutzia, Culex, Grab- 
1 Some good adult character for the separation of the Anophelinae can 
surely be found.
