CULEX INHIBITATOE Dyar & Knab. 



Culex inhiiitator Dyar & Knab, Journ. N. Y. Ent. Soc, xiv, 207, 216, 1906. 

 Culex inhibitator Dyar, Proc. Ent. Soc. Wash., vlii, 17, 1906. 

 OsiaiNAL Descbiption of Culex inhibitatoe: 



Antennae with the tuft near the outer third, dark; upper head tuft of four, short, 

 lower long and single; body hairy; lateral hairs in twos after the first abdominal 

 segment; tracheae narrow. Air tube long, 6X1, the pecten long and reaching one- 

 third, with five tufts, decreasing in length a little toward tip. Anal segment long, 

 but the gills short. 



Collected by Mr. Busck in a slowly running clear cold spring in the San Fran- 

 cisco Mts. of San Domingo. It was named " Melanoconion indecorabUis Theob." by 

 Mr. Coquillett, but that was described from Para, Brazil, and we do not believe it is 

 our species. 



The following is an abstract of the table :

5. Air tube four times as long as wide or over 7 



7. Anal appendages four, normal 8
