Culc.v comitatus has the same habits as its congener, quin- 

 quefasciatus. The larvse occur in all sorts of artificial accum- 

 ulations of water, and the adults frequent houses and attack the 

 inmates at night. 



Type No. 12201, U. S. Nat. Mus. 



Culex restuans Theobald. 



The genitalia (fig. 5) have the harpes with a distinct, though 

 short hasal projection (fig. 5, &). Harpagones divided into 

 three plates; first plate (fig. 5, c) narrow, rather short, with 

 rounded pointed tips ; second plate broad, short, the tip broadly 

 rounded, with small reversed teeth near the middle and a large, 

 sharp, angular spine projecting outward from near the base; 

 third plate (fig. 5, /) essentially as in pipiens, but shown fore- 

 shortened from side view in the figure. 



The genitalia agree with those of quinquefasciatus in the 

 number of divisions of the harpagones, but are readily distin- 

 guished by the peculiar form of the second division, with its 

 large lateral tooth. 



This species agrees with the foregoing ones in the vestiture 

 of the mesonotum, which consists of the ordinary narrow, 

 curved scales, which cover the surface rather completely. In 

 all of the following the vestiture is of minute, hair-like scales, 

 not covering the surface. The dentation of second division of 

 the harpagones allies the species with the next group, typified 

 by Culex similis Theobald. This species, therefore, stands by 

 itself, allied to both the pipiens and similis groups, but more 

 closely to the former. 



Culex salinarius Coquillett. 



The genitalia (Plate in, fig. 7) have the harpes with a long 

 curved arm from the outer base (fig. 7, b}. Harpagones 

 divided into two plates ; the outer one (fig. 7, d} a broad plate 

 with a series of long teeth, which lie nearly in a plane, a large 

 tooth above, partly separated, and an upcurved one below are 

 separated by a row of smaller, more even teeth ; inner plate 

 concave, tapering to a rounded tip (fig. 7, /). 



The species is especially characterized by the absence of the 

 long lateral tooth of the outer plate of the harpagones, which 

 is present in the two following species. 



This species, together with the following ones, similis Theo- 

 bald, factor Dyar and Knab, and pro.vimus Dyar and Knab, 

 form a distinct group, separate from the pipiens group. We 

 should not discuss them in this connection, except that the simi- 

 larity of coloration of the adults has led to confusion. The
