Fig. n.—Mantispa inlerrupla. 

 of hind wing. 



Part 



the media fuses with that 

 of the radius for some 

 distance; and, in the an- 

 terior wing, Fig. 10, the 

 media dips down and then 

 fuses with the radius again 

 thus forming a small tri- 

 angular cell. After the 

 media is finally free it 

 divides into the typical 

 number of branches. 



CHRYSOPID^. 



In the Chrysopidce we find a great modification by coales- 

 cence. 



In the anterior wing of Chrysopa plorabunda, Fig. 12, the 

 veins in the middle 

 run zigzag and fuse 

 at their angles, 

 forming a reticular 

 structure without 

 the interposition of 

 true cross veins. 

 The so-called 

 ' ' cross vein ' ' of 

 the " third cubital 

 cell " (ra 3 + 4 ) behaves in a very peculiar manner : ra 3 + + runs 

 obliquely forward and coalesces for some distance with n£ + 2 , 

 and then separates from it again. 



The hind wing, Fig. 13, resembles Myrmeleon, save that rs 

 and m coalesce for some distance. 



12. — Chrysopa plorabunda. Fore wing. 

 Where veins have coalesced I have 

 represented them slightly separate 

 for clearness of interpretation.
