Another most interesting portion OF this
work Is the rearing CT certain species to
work out their i.fe histories. No work OF
this kind has been done with the Pacific
coast beetles, except the twelve species
worked out by Mr.. Ksncald. Prof. Need
ham. OK Cornell university. Is working
out the life histories Of the dragon fiies
and Mr.. kincasi IL assisting him by rear
ing the local forms The dragon fy Is
very active animal in the water before he
crawls up on stick or straw and, break
ing from his swimming suit, starts of on
new career with very servlceahie wings.
Last year Mr.. hIncaid reared some iies
from tha larvai stage TO the adult. He
then collected the eggs and reared them
back 20 the larvae again. thus completing
the circle OF their life history.
Pests ON Forest Trees.
