Family Polysixechotid,e 



The family Polystoechotidas was established to receive the genus 

 Polystoeckotes, of which only two species, both 

 American, are known. These are larger in- 

 sects than are the members of the allied 

 families, measuring in wing-expanse from if 

 inches to 3 inches. They are nocturnal in 



habits (Fig. I2o). Fig. 120. — Polystcecholes punctatus.

 ica by a single genus, Lomamyia, of which only two species are known.

The family Ascalaphidas is quite closely allied to the 

 Myrmeleonidas ; but the members of this family can 

 usually be distinguished from myrmeleonids by the greater 

 length of the antennas. The larvae resemble ant-lions in 

 form of the body and possess the same type of mouth- 

 parts (Fig. 121). 



Family Coniopterygid^e 



The Mealy-winged Neuropterons 



The Coniopterygidas is a family of limited extent; and it includes 

 only small insects, the smallest of the Neuroptera; the described Amer- 

 ican species measure only 3 mm. or less in length. They have the body 

 and wings covered by a whitish powder.
