Behaviour of Goleoptera in time of Floods. 385 
a moment to dry it. When Gnypeta labilis was flooded off 
a piece of grass, it remained standing on the water with 
the abdomen curled up over the body. In this attitude it 
was blown along at a surprising speed by a very slight 
breeze. It also took flight directly from the water. 
As might be expected a great many species of Coleoptera, 
which must only very accidentally find themselves in 
water, are quite helpless when they get there; among 
them I may mention, Bhizohius litura, Hypera nigriros- 
tris, Apion, Oxytelus, etc. Drusilla canaliculata lay 
motionless for some time, then after some trouble cleared 
itself of the water enough to swim, keeping the antennae 
raised and constantly moving. Myrmedonia collaris be¬ 
haved in much the same way, floating to the top in the 
form of an S with the underside of the abdomen upper¬ 
most, and remaining in this position for some minutes.
