Vol. XI] COLE AND LOVETT—LIST OF OREGON DIPT ERA 213 



Family CERATOPOGONID^ 



We follow Malloch in making this group a family sep- 

 arate from the Chironomidae. Here belong the "punkies" or 

 "no-see-ums" which are wicked biters and are so small that 

 an ordinary net will not keep them out. The thorax is large, 

 but does not project over the head as in the true Chirono- 

 midae. The species of Culicoides are especially bloodthirsty; 

 some of the other genera are said to attack insects, attaching 

 themselves to the body and wings. 



The larvae of most are aquatic or semi-aquatic, often being 

 found in decaying wood that is submerged.
