THEOBALDIA INORNATA (Wiil.) 

 (Syn., Citlea consobrlnus How. (not R.-D.)) 



This is a rather large species, which breeds in open grassy pools 

 and occasionally in artificial water receptacles. It is widely dis- 

 tributed throughout the United States. In the South the larvae and 

 adults are encountered usually only during the cooler months. In 

 New Orleans the larvae were sometimes found in abundance during 

 the winter, but they disappeared completely from March to Novem- 

 ber, and the manner of passing the summer is unknown. The larvae 

 were usually found associated with those of Culex restuans. In 

 Florida the writers have taken the species at Zellwood and Palm 

 Beach. 



THEOBALDIA MELANURA (Coq.) 



Theob aldia melanura breeds in small permanent collections of 

 water. It is rare and of sylvan habits but occurs over a wide range 

 in the Southern and Eastern States. The writers have taken the 

 species at Mound and New Orleans, La,, Wilson Dam, Ala., and in 

 several places in Orange County, Fla. It has now been recorded from 

 all the Southern States except Mississippi and Tennessee. 



Genus URANOTAENIA Lynch-Arribalzaga 



The members of this genus are very small, and some are brilliantly 

 colored. They are recognized as a group by the very short forks of 

 wing vein 2. The palpi of both males and females are short, but the 

 male antennae are plumose. The eggs are laid in irregularly shaped 

 rafts on the surface of permanent bodies of water in which there is 

 considerable plant growth. The larvae are commonly associated with 

 anopheline larvae and, when viewed in the water from above, some- 

 what resemble the latter in the shape and dark color of the head and 

 the position of the body. Three species are found in the United 

 States, and two of them occur in the Southeast, neither of which is of 

 economic importance. Hinman (61) has published some biological 

 notes on these two species in southern Louisiana. 



URANOTAENIA SAPPHIRINA (O.-S.) 

 (Syn., U. socialis Theob.) 



This mosquito breeds in grassy pools, swamps, and vegetation at 

 the margins of lakes. The adults are rarely seen on the wing but may 

 be found resting in hollow trees and in the grass or around the bases 

 of trees and stumps in swampy places. They are said to bite humans 

 on occasion, but their biting has never been observed by any of the 

 writers. The specific name comes from the median longitudinal line 

 of brilliant blue scales on the mesonotum. The species is a common 

 one and undoubtedly occurs throughout the South, although it has 

 not yet been recorded from all the States. 



URANOTAENIA LOWII Theob. 



(Syn., U. continent alis D. and K.) 



The larvae of this species occur in ground pools, chiefly the grassy 

 margins of lakes. The adults are rarely seen and are not known to 

 bite humans. The species has been recorded only from Florida and 

 Louisiana, In southern Florida it appears to be the predominant
