The anal branchiae are little more than four times longer than 

 wide, and about equal to the 5th, 6th and jih abdominal seg- 

 ments taken together ; each branchia has a median longitudi- 

 nal trachea with short lateral rami that may divide once or 

 twice ; small rounded areas are to be observed scattered 

 sparsely within the branchia, within each circle is a small 

 central circle. The brauchia are easily detached. 



The setae of the larvae are peculiar, inasmuch as they are 

 clothed with fine hairs. Figure 5 represents the basal part of 

 a thoracic tuft, while figure 2 illustrates a tuft from the 

 eighth segment. 



The larvae are fragile, especially in preservative fluids. 



In the pupae the respiratory siphons are small and compara- 

 tively inconspicuous, while the two anal branchiae are nearly 

 oval, slightly longer than wide, slightly and rather broadly 

 emarginate at apex, with a small, slender seta projecting back- 

 wards from the centre of the emargination ; margins at sides 

 are minute spinulo-denticulate, at apex minutely spinulose. 



As a whole the pupa is slender, the abdomen elongate, and 

 distinctly dorso-ventrally depressed. 



A new Culex near curriei. 



BY D. W. COOUILLETT. 

 Culex lativittatus, n. sp. 



So very similar to curriei that I am unable to detect any difference, 

 except in the stripe of brown scales in the middle of the mesonotum. In 

 the present species this stripe is very broad, covering more than one-fifth 

 of the width of the mesonotum, the borders almost parallel and well 

 marked. In curriei this stripe is much narrower, covering less than one- 

 ninth of the width of the mesonotum, its borders not well defined, usually 

 with a narrow line of brown scales on either side of it, but separated by 

 a stripe of yellowish white scales. 



Santa Clara and Alameda Counties, California. A large 

 series of both sexes received from Miss Isabel McCracken. 



This is evidently the species referred to by Mr. Ouayle in 

 the January number of the NEWS, under the name of curriei. 

 The latter appears to be a fresh-water species. Mr. Frederick 

 Knab informs me that the larvae of the two forms arc very 

 distinct.
