BORNEAN CICINDELIDAE, 191 
September. I took plenty of this form flying over and 
alighting on the boulders in the small streams which 
form the sources of the Lawas River in the Marapok 
Mts. Its quick flight and procryptic colouring made 
it extremely hard to see and follow. It is curious that 
the same effect of invisibility is obtained by Cicindela 
crespignyi Bat., which has similar markings except 
that a dull grey-green ground-colour takes the place 
of the glossy black of this Zherates. I have taken 
them both in the same locality and have thus had a 
good opportunity of comparing their respective powers 
of protection in real life.
