Genus Psorophora. 159 



last volume, the life-history of Psorophora ciliata, Fabr., has been 

 worked out by several observers. It is incorporated here under 

 the name of that species. 



Several naturalists still confuse this genus with Mucidus. If 

 they examine the scale ornamentation, they can be separated 

 at once. No Mucidus has yet been found outside Africa and 

 Asia. 



Coquillett has wrongly referred fulvus, Wiedemann, to this 

 genus. Coquillett has also identified Fabricius' cilipes as a 

 Psorophora.

Observations on habits, etc. — In New Jersey this large 

 mosquito occurs from June to early October. The bite is not 

 very poisonous, but it bites through clothing, even " coat, vest,. 

 and two shirts to the skin." Smith records that it prefers 

 horses to man. It may occur indoors. Its flight is heavy and 

 slow.
