The harpagones are a pair of smaller clasping organs lying above 

 the harpes and within the base of the clasps. They are usually 

 strongly curved, terminated by a stout, somewhat recurved hook 

 and are attached to the rudimentary eighth segment in some cases 

 at least. These organs in the Anophelinae, if we have correctly 

 homologized the parts, and in certain Culicinae, bear conspicuous

terminal chitinous spines. They are usually divided in Culex proper 

 and in certain species there appear to be more than the normal 

 ntmiber of organs on account of this peculiarity. This tendency is 

 well illustrated in 

 Culex annul io- 

 r i s Theo., C. c o n - 

 color Rob. & Desv. 

 and C. tigripes 

 Grand. This process 

 seems to have gone 

 farther than in our 

 native species, so that 

 without the evidence 

 afforded by these ex- 

 otic forms it would 

 be difficult to pro- 

 perly homologize the 

 parts. 



The -unci, as we 

 have identified them, consist of a pair of processes on the 

 ventral margin and present considerable variations in struc- 

 ture. These organs are readilv seen in most of the Culicinae, while
