MOSQUITO FAUNA OF PANAMA BUSCK 69 



this nor the following species were secured by Mr. Jennings and the 

 writer during our visit to Taboga Island, six weeks previously to Mr. 

 Jennings' last visit. As our investigations were careful and covered 

 practically every water accumulation on the island, including the 

 above-mentioned tub. this can only be explained by the periodicity of 

 the activity of these mosquitoes. On Air. Jennings" second visit he 

 failed to secure several of the species I took during my stay on the 

 island, which is not so large, but that it can be thoroughly explored in 

 a few days. 



CULEX REVELATOR Dyar and Knab 



Bred by Air. Jennings from an old rain-filled boat on Taboga 

 Island. 



CULEX HESITATOR Dyar and Knab 



Bred from a small swampy stream near Las Cascadas. 



CULEX ELEVATOR Dyar and Knab 



The larvse of this species are dark prettily marked with black, 

 "zebra-striped." They were taken in a slow-running spring, full of 

 leaves and small fishes, which evidently did not seriously interfere 

 with the mosquito larvae : it was also bred from the edges of a small 

 stream full of fishes, near Tabernilla. 



CULEX TiENIOPUS Dyar and Knab 

 A single adult specimen was taken. 



CULEX CORRIGANI Dyar and Knab 



Bred from small larvae with very long, slender tubes, taken in 

 bamboo- joints near Tabernilla. 



The species is named in honor of my friend. Air. J. Corrigan, 

 Sanitary Inspector at Tabernilla, whose efficient work has made that 

 place one of the healthiest settlements in the Canal Zone. His con- 

 stant courteous attention to my needs greatly facilitated my work 

 and made my sojourn in Tabernilla very pleasant. 



CULEX JENNINGSI Dyar and Knab 



Bred from larvae taken in water in the leaves of bromelias, Til- 

 laiidsia sp., in a tree in the native village near Tabernilla, associated 

 with Phoiiioniyia scotiiiouius and Wycomyia circinncincta, and with 

 these was preyed upon by the larvae of Megarhinus siipcrhus. This 

 species is named in honor of my friend, Air. Allen H. Jennings.
