630 MOSQUITOES OF NOETH AMEEIOA 



white. Fore and mid tarsi brown with apical white rings, hind tarsi with the apex 

 and the extremities of the segments distinctly ringed, except the distal of the fourth, 

 fifth snow white. Claws unidentate. Wings hyaline, clothed with intermixed brown, 

 straw yellow and colorless scales, the narrow long ones mostly transparent. Petioles 

 of the first and second fork cells about three fourths the length of their respective 

 cells. 



Oeiqinal Description or Aedes qtjatlei: 



This species is the salt marsh form of the Pacific Coast, as shown by Quayle. 

 The types of curriei were from diverse localities, but the North Dakota specimen 

 must be regarded as the actual type in restricting it. This form has never been 

 bred; it cannot be the same species as the Calif ornian salt marsh species. It may 

 be conspecific with the specimens from New York mentioned above under A. gross- 

 becki, but this has yet to be proved. 



The following is an abstract of the table : 



1. Air tube with the tuft beyond the pecten 8 



8. Pecten of the air tube with evenly spaced teeth 13 



13. Comb scales more numerous to many in a patch 21 



21. Anal segment not ringed by the plate 31 



31. Tube three times as long as wide or less 32 



32. Anal plate covering more than half the segment; anal gills 



moderate 33 



33. Comb scales bluntly ended, the median spine resembling the others. 40 



40. Antennae normal, short, stout 41 



41. Antennas spinulated 42 



42. Anal gills very short, bud-shaped quaylei 



Obiginai Descbiption or Cuiex lativittatus: 



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-flfth of the width of the mesonotum, 

 the borders almost parallel and well marked. In curriei this stripe is much nar- 

 rower, 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. Quayle 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 are very distinct. 



Description of Female, Male, and Labva op Aedes onondaqensis: 



Female. — Proboscis moderate, subeyliadrical, uniform, labells conically 

 tapered ; vestiture of blackish-brown scales, blacker on the labellse ; setse minute, 

 curved, black. Palpi short and stout, about one-fourth as long as the proboscis ; 

 vestiture black with a few white scales intermixed ; setse rather long and black. 

 Antennse moderate, with the joints subequal, rugose, pilose, blackish, the second 

 joint a little longer, with a yellow base; tori subspherical, with a cup-shaped 

 excavation, largely shaded with blackish, the inner half covered with small, flat, 

 sordid white scales. Clypeus rounded-triangular, prominent, black, nude. Byes 

 black. Occiput rather broad, black, densely covered with narrow, curved, coarse 

 scales, nearly pure white in a broad median zone, brown laterally, a patch 

 of flat blackish ones on the sides, many erect, broad and rather short, white 

 forked scales centrally, a few black ones laterally. 



Prothoracic lobes narrowly elliptical, remote dorsally, clothed with narrow 

 coarse dark-brown scales at tip, whitish ones below, and with short brown bristles. 

 Mesonotum black, densely clothed with coarse, narrow, curved, dull-yellowish 

 scales laterally, golden-brown ones in a broad median stripe, a marginal stripe 

 of the same color from anterior angles to near root of wing, a short stripe 

 behind on either side of antescutellar space ; scales paler in the region of ante- 

 scutellar space j bristles dark brown. Scutellum trilobate, luteous, clothed witli 

 coarse creamy white scales, each lobe with a group of about twelve pale
