CHIRONOMID MIDGES OF CALIFORNIA. 



I. CIIIRONOMINAE, EXCLUSIVE OF TANYTARSINI 



(=CALOPSECTRINI) 



By James E. Sublette l 



The nonbiting midges of the family Chironomidae occurring in 

 California have been reviewed by Wirth and Stone (1956). Only 

 the Clunioninae (Wirth, 1949) and the Tendipedini (Townes, 1945) 

 have been adequately treated. The Chironominae exclusive of Tany- 

 tarsini are dealt with here. Of the 71 species of Chironomini report- 

 ed here as occurring in the State, 47 were not previously listed. The 

 Tanytarsini of California will be incorporated in a revision of the 

 Nearctic species which I now have in progress. A projected sec- 

 ond part to this paper will include the remaining subfamilies ex- 

 clusive of Clunioninae. 



Genitalia mounts were made of all male specimens studied. The 

 genital capsule, after KOH clearing, was mounted in "Permount/' 

 a synthetic mounting resin, on a small celluloid strip following the 

 technique used by workers in the British Museum (Natural History). 

 The technique was modified by using a cover glass on the mount. 

 The celluloid strip was then pinned under the locality label on the 

 specimen pin. In some instances accessory slides were made of 

 antennae and legs. 



The terminology of wing venation used follows Townes (1945) 

 for consistency although Freeman (1955) favors the Tillyard mod- 

 ification of the Needham-Comstock system.
