ORDER X. STREPSIPTERA,Kirby. J^A^^em, Lat. 



Two naked membranous wings, accompanied by two balancers, 

 longitudinally folded, forming nearly the quadrant of a cir- 

 cle ; metamorphosis incomplete ; anus styliferous. 



This order was established by Mr Kirby, and afterwards adopted by Latreille, who 

 changed the name, without any very good reason, to Rhipiptera. On each side of 

 the anterior extremity of the trunk, near the neck and exterior base of the first pair 

 of feet, are inserted two small crustaceous moveable bodies, in the form of small 

 elytra. They are narrow, tortuous, elongated, dilated and clavate, and termi- 

 nate at the origin of the wings. These bodies Latreille considers as a kind of pois- 

 ers or balancers, while others consider them as a species of elytra or wing-cases. 

 The mouth is composed of a labrum, two mandibles, and two jaws, bearing minute 

 palpi of one joint, and a lip without palpi. The eyes are large, hemispherical, gra- 

 nulated, and slightly pedunculated. The antennas are approximated at the base, up- 

 on a common elevation, and are composed of three joints, of which the first two are 

 very short, the last long, and divided into two branches. The mesothorax is pro- 

 longed like a scutellum ; the abdomen cylindrical, and of eight or nine segments ; 

 and the feet are almost membranous, compressed, of four joints, without hooks at 

 the end. The four anterior ones are approximated before, and the other two thrown 

 backwards. The wings have slight longitudinal nerves, and fold longitudinally like
