from vines on trees and against houses ; but always from above 

 and always ready to bite. 



, The species sings and where many of them are about, the air 

 is filled with an angry buzz that is quite unlike the preparatory 

 note of any other species known to me. 



Dr. Dupree, of Baton Rouge, told me that he had dissected 

 a female with partly developed ovaries and that the eggs seemed 

 like those of pipiens; but that would make this a species unlike 

 in appearance to any other of which we know that it makes 

 an Q.gg boat. As to the method of hibernation, nothing is known 

 save that we have never found it as an adult during the winter. 



The Brakeley records would seem to indicate a single brood 

 only, with a long life; but the occurrence of a male in late July 

 and of a female with developed ovaries a little later, are pointers 

 in another direction. 



Fortunately the species is not of serious economic importance, 

 though it is locally common. 



CULEX T^NIORHYNCHUS, WIED. 



The Small Salt Marsh Mosquito. 



This is a small black moscjuito with narrow white bands at the 

 base of the abdomen. The beak has a narrow white ring at its 

 center and the legs are ringed with moderate bands of white at 

 the bases of the tarsal joints; the last joint of the hind feet being 

 entirely white. In worn specimens this insect might be taken for 

 an undersized C. soUicitans, but can be separated at once from that 

 species by the absence of the longitudinal stripe on the abdomen. 



Description of the Adult. 



This is a small mosquito, ranging between 4 to 5 mm.,=.i6 to 

 .20 of an inch exclusive of the beak, which is about 2.4 mm. in 

 length. The head is dark brown with a few yellowish scales, 

 which sometimes make a diffused patch in the angle formed by 

 the eyes ; the proboscis is blackish brown with a creamy white ring 

 at about its center, slightly nearer the base. The palpi in the 

 female are brown, becoming blacker distally, the extreme tips 

 pure white; the terminal joint is small, almost rounded and cov- 

 ered with short, fine spines. In the male the palpi are shaped 

 something like those of C. soUicitans, but are not so robust and 

 the terminal joint is shorter; they are black in color, with narrow 

 white rings at the base of the two terminal joints, and there is a
