SYSTEMATIC ACCOUNT OF NORTH AMERICAN<br />

CULICIDAE<br />

The family Culicidae consists <strong>of</strong> two well defined sub-fami-<br />

lies. These are <strong>the</strong> C’jznobori~znc (Coretlzrinae <strong>of</strong> authors) and<br />

<strong>the</strong> Culicinae. The members <strong>of</strong> <strong>the</strong> former are readily separ-<br />

ated by <strong>the</strong> fact that <strong>the</strong> mouthparts <strong>of</strong> <strong>the</strong> females are not<br />

fitted for piercing. This sub-family is not treated fur<strong>the</strong>r in<br />

this <strong>handbook</strong>. In <strong>the</strong> Culicinae, <strong>the</strong> mouthparts <strong>of</strong> <strong>the</strong> females<br />

are elongated and fitted for piercing and sucking.<br />

SUB-FAMILY CULICINAE<br />

The sub-family Culicinae contains all those species which<br />

possess an elongated proboscis fitted for piercing. Most <strong>of</strong><br />

<strong>the</strong>m, especially our nor<strong>the</strong>rn species, are blood-sucking in habit.<br />

A few are not known to suck blood and some live on plant<br />

juices. The Culicinae are divided into two tribes--A#zopheZini<br />

and Culicini.<br />
