CULEX SALINARIUS 373 



two filaments below middle and a spine on other side. Palpus small, tapered, 

 with fovir rather long irregular apical digits. Thorax rounded, wider than long; 

 abdomen moderate, anterior segments shorter; lateral hairs in fours on first 

 abdominal segment, in threes on second, in twos on third to sixth ; subdorsal 

 hairs very long, in twos or threes on fourth to seventh segments ; tracheal tubes 

 rather broad; skin pilose. Air-tube long, slightly tapered, six times as long as 

 wide ; pecten reaching about one-third ; single teeth broad with four to six 

 branches ; four two-haired tufts on posterior margin beyond pecten, the one 

 before the last moved laterally out of line. Lateral comb of eighth segment of 

 many spines in a triangular patch ; single spine elongate, widened at tip, with an 

 apical fringe of spinules. Anal segment longer than wide, ringed by the plate ; 

 dorsal tuft a group of long and short hairs on each side; a single lateral hair; 

 ventral brush well developed, confined to the barred area. Anal gills moderately 

 long, slightly longer than the segment, with ensiform tips. 



The larvae live in ground-pools. Mr. Knab got them in small puddles, in foot- 

 prints in a muddy roadway, in a shallow puddle of discolored water, and in 

 some pools near a beach ; Mr. Jennings got them in a swamp near the sea. 



Southern Mexico and Central America. 



Tehuantepec, Mexico, July 3, 1905 (F. Knab) ; Santa Lucrecia, Mexico, June 

 19, 1905 (F. Knab) ; Salina Cruz, Mexico, July 9, 1905 (F. Knab) ; La Boca, 

 Canal Zone, Panama, N"ovember 19, 1907 (A. H. Jennings). 



Our typical specimens came from southern Mexico, and we later obtained 

 others from Panama. In our first description, we included specimens from St. 

 Vincent, Barbados, and Martinque, with some doubt, as the larval sldns had been 

 injured. We now separate the specimens from Barbados under the name Culex 

 caraibeus, and have referred the St. Vincent specimens to Culex similis; the 

 Martinique specimens appear to be another species, but, as we have male adults 

 only and the larval skins are damaged, we have been obliged to leave the species 

 undetermined, although excluded from Culex factor. The specimen recorded by 

 Mr. Busck (Smiths. Misc. Colls., quart, iss., lii, 70, 1908) proves to be really a 

 specimen of Culex revelator, with abnormal markings, and will be found r\is- 

 cussed under that specific heading.
