The widely ranging species territans varies somewhat in general color and 

 considerably in the thoracic ornamentation and the width of the white abdom- 

 inal bands, but does not divide into specific forms. The forms described by 

 Adams, Grossbeck, and Ludlow appear to us to be variations only, and we ac- 

 cordingly quote them in the synonymy ; we have bred all the extreme forms from 

 identical larvae and the male genitalia agree. We have before us colypes of 

 Culex saxaiilis Grossbeck. There is a slight local alteration in the male geni- 

 talia of specimens from California and Mexico, indicating the beginnings of 

 geographical races. In the specimens from California, the harpagones exceed 

 the harpes considerably, while the tips of the lateral filaments of the side-pieces 

 are narrowly appendieulate ; in the Mexican specimens the harpagones are also 

 long, but the filaments have rounded tips. In the Mexican form the basal ap- 

 pendages are united by a distinct chitinous band. We think these incipient local 

 races scarcely worthy of diflEerential names. 



At our suggestion Mr. F. W. Edwards has examined Walker's type of CvJex 

 territans in the British Museum and informs us that it is identicad with Cidex 

 restuans Theobald; therefore Coquillett's identification, which we use, is in 

 error. The present species must, therefore, be called Cidex saxaiilis, while 

 G. restuans will become a synonym of Cidex territans. This information 

 reached us too late to make the necessary changes in the present work. 



CULEX BAHAMENSIS Dyar & Knab. 



Culex iahamensis Dyar & Knab, Journ. N. Y. Ent Soc, xiv, 206, 210, 1906. 

 Obiginai. Debcbiftion of Ctxlex basamensis : 



This very peculiar species was collected by Dr. T. H. Coffin in the Bahamas, but, 

 although he preserved pupae, he obtained no adults. The skin is glabrous, but 

 curiously enough, the air tube is pilose outwardly. The lateral hairs in threes 

 on the third and fourth segments, in twos on the fifth and sixth. There are but a 

 single pair of anal gills, a character only paralleled in Wyeomia. The six tufts of 

 the air tube are arranged in a line along the posterior margin, three of them within 

 the pecten. 



The following is an abstract of the table : 



1. Antennae with the tuft outwardly placed, the part beyond slender. 5 



5. Air tube four times as long as wide or over 7 



7. Anal appendages only two bahamensis 



DESCBIPTION of LaBVA of CtTLEX BAHAMENSIS (AdTILT UnKNOWN) : 



Larva, Stage IV (plate 107, fig. 359). — Head rounded, widest through eyes, 

 narrowed before, a notch at insertion of antennae, front margin arcuate. An- 

 tennae large, stout on basal two-thirds, well spined ; a large tuft from a notch at 

 outer third; two long setae some distance before tip, a long seta, a short one.
