368 INSECT MISCELLANIES. 



use among collectors ; since we can by their means 

 more readily remember the different plants on which 

 several species were found, besides avoiding the 

 risk of one species devouring another, an incident 

 not uncommon among the caterpillars of moths, as 

 we have recorded in a former page. The collec-

 reach. The net which we have had constructed con-

 procured by mere inspection of water-plants, particu- 

 larly the under-sides of their leaves, at the edges of 

 ditches, ponds, canals, rivers, and lakes, and when 

 the water is clear, by examining the bottom of the
