Our most common species in the Summer time, breeding in all the 

 swamps especially if cold and clear. It seems entirely harmless as we 

 have never been bitten by a specimen. The adult is in fact seldom 

 seen, being of retiring habits. It may be obtained by sweeping the 

 bushes. 



The species occurs throughout the United States. We may men- 

 tion Springfield, Mass. (Knab), Ithaca, N. Y. (Johannsen), Lahaway, 

 N. J. (Brakely), Baltimore, Md. (Dyar and Caudell), Baton Rouge, 

 La. (Dupree), Stanford Univ., Cal. (MacCracken) , Kaslo, B. C. 

 (Dyar and Currie). 



Culex simulator, new species. Fig. 46. 



Antennae with the tuft at outer third, dark ; upper head tuft double, 

 lower single ; body smooth ; lateral hairs single on the second abdomi- 

 nal segment, double on the third to sixth ; tracheae narrow. Air tube 

 7x1, slightly flared at tip, with five tufts on the posterior margin; 

 pecten very long, reaching one-third ; lateral comb of the eighth seg- 

 ment scarcely over two rows deep. Anal segment long. 



Taken by Mr. Busck in Arima, Trinidad, in the primeval woods. 

 No adults were obtained. 



Culex gravitajtor, new species. Fig. 47. 



Antennae with the tuft before the outer third, dark ; hairs single ; 

 body glabrous ; lateral hairs in threes on abdominal segments 3 to 6 ; 

 tracheal tubes narrow, angulated within the segments. Air tube 

 six-and-a-half times as long as wide, with long pecten reaching to 

 one-third. Anal gills small. 



Collected by the junior author in a large Bromeliaceous plant con- 

 taining water between the leaves, growing in a ticket in a valley 

 above Cordoba, Mexico. In spite of careful atteWBn no adults were 

 bred. Some of the larvae lived two months after being collected; 

 they probably died of starvation. 



Culex decorator, new species. Fig. 48. 



Antennae with the tuft beyond the outer third, dark ; head hairs, the 

 upper tuft triple, the lower single ; lateral hairs double on the second
