CHAPTER I. 

 SYSTEMATIC ARRANGEMENT. 



a. GENERAL CEASSIEICATION. 



The family CuUcida:, or mosquito, belongs to that section of 

 the order Diptera, or flies, in which the antennae, or feelers, are 

 long and many jointed. They are slender, long legged and nar- 

 row winged, of moderate or small size, and differ from all the 

 other similar flies by the venation which is as figured and de- 

 scribed on page 7. The fringing of scales is also peculiar, and 

 that will be illustrated for the various genera where they differ 

 sufficiently. 



The family is broadly divided into two series: The Cnliciiii, or 

 true mosquitoes, which have long beaks covering lancets, meant 

 for piercing or "biting," and the CorctJirini, which are of stouter 

 build and have nO' beak or lancets fitted for ])iercing or biting. 



The Culicini, or true mosquitoes, tliat occur in this State are 

 divided among seven genera, which are usually recognized with- 

 out much difficulty. 



1. Anopheles, in which the palpi, or mouth feelers, are long 

 in both sexes, reaching to or exceeding the tip of the beak. The 

 abdomen and body in general are slender, the legs long and thin 

 and the wings more or less spotted. When at rest the body is 

 held at nearly right angles to the surface and the hind feet are 

 directed high in the air. 



2. Ciilex, in which the palpi, or mouth feelers, are long in the 

 male, equaling or exceeding the proboscis in length, and short 

 in the female, not extending even to the middle of the beak. The 

 body is stouter than in Anopheles, the legs are not quite as long
