mosquito a peculiar and very characteristic awl-like 
appearance (Fig. 20). 
^4. The attitude adopted by Ano'phelines is, as a 
rule, characteristic. When an Anofheline rests upon 
a wall, its body projects so as to form a distinct angle 
with it. In some cases the angle assumed is almost a 
right-angle. In the case of almost all other mosquitoes 
the body is held either parallel with the wall, or what 
is more frequent, the tail approaches the wall, giving 
the^insect a ‘ hunchbacked 5 appearance. This differ¬ 
ing. 20. Shewing distinction between resting attitude of 
an Anopheline {left) and Faeniorhynchus {right) 
ence is readily seen by any careful observer, and is a 
practical and useful distinction. A characteristic of 
an Anofheline is that it rests by preference on the first 
two pairs of legs only, and keeps the last pair stretched 
out stiff and straight , or they slowly oscillate to and fro. 
Many mosquitoes wave the hind legs, notably Stegomyia , 
but they are held with the tarsi curved upwards.
