REPORT OX MOSQUITOES. 315 



The abdomen is blackish brown, with the pale yellowish bands 

 narrow in the female and broader in the male. 



Habits of the Adult. 



The habits of this species are practically like those of pipiens. 

 It winters in the same way and under the same conditions; its 

 biting methods are much the same. and. in fact, so far as the 

 adult is concerned everything that has been said of pipiens 

 applies to this form as well. It seems to occur throughout the 

 State, but is not quite so- common as its better know ally. When 

 the specimens are rubbed or have been in alcohol, there is no way 

 of detennining them positively as distinct from pipiens. 



Description of the Larva. 



In general apearance this larva resembles Culcx pipiens so 

 closely that the figure on page 310 serves for both species; some 

 of the details, however, depart so widely from that species that 

 it is at once recognizable. It differs from C. pipiens as follows : 

 Antenna (fig. 97, 6 and 7) pale brown, whitish at the basal 

 half with the tuft well below the middle ; the hairs composing the 

 tuft are shorter, only ten tO' fifteen in number, and are situated 

 on a comparatively small offset. The surface is covered with 

 hair-like spines and the apex is one long and two shorter 

 spines, a few short hairs and a small joint. The mentum (fig. 

 97 J 5) is peculiarly shaped, almost square in form, rounded at 

 the apical margin and excavated inwardly at the base. Each side 

 has three or four teeth, the central ones largest ; the anterior mar- 

 gin has from seventeen to twenty-three small, evenly shaped 

 teeth. The anal siphon is similar tO' that of C. pipiens, both 

 species varying in length somewhat ; but there are a few more 

 spines to the lateral row in restuans. The anal gills are long, 

 not pointed and with circular spots scattered over the surface. 



Habits of the Early Stages. 



Eggs are as in pipiens, to all appearance. Both species occur 

 in my pails and I have frequently examined the egg boats to 

 determine, if possible, whether any superficial differences exist, 

 but have never found any. In general appearance and habits the 

 larv?e are also similar ; but restuans is not fecund in really foul 

 water, in my experience. In life the two species are readily dis- 

 criminated by the antenna?, which, are always prominently spread 

 out, SO' that the position of the tuft is readily noted. The wrig-
