IV. Chrysopidae. 



In tbis family tbe nervature of tbe wings is formed in 

 a peculiar manner, and we meet bere witb a great modifi- 

 cation, caused by coalescence. 



M forks in tbe forewing before origin of Rs; but in tbe 

 genera Ghrysopa, Anomalochrysa and Ankylopteryx M.y bends 

 upwards and coalesces witb M^ for a distance. Tbe cell at 

 tbe base of the median fork takes in these genera form of 

 an irregular triangle. As Mc Clendon^ and Tillyard^ ha ve 

 stated M^ and M2 run into tbe bind margin of the wing be- 

 fore its middle. Tbe straight nervure running througb the 

 middle part of tbe wing is formed, partly by M^ and partly 

 by tbe coalescing of bent branches from Rs. Tillyard na- 

 mes tbis nervure tbe pseudo-media (Psm). In the genus 

 Noihochrysa M^ does not coalesce witb M^, but it is con- 

 nected to M^ by a short crossvein. In tbe bindwing M forks 

 closer to tbe base than in tbe forewing, but in a regular 

 manner. M^ coalesces witb tbe basal part of Rs for a short 

 distance. Botb M^ and I/2 run into the bind margin of the 

 wing before its middle, and we find also bere a pseudo- 

 media. In botb pairs of the wings Cu forks before M. In 

 the bindwing Cu^ and Cu^ botb run directly into the hind-
