NSADZI TO KOME 101 



every blade had been eaten by caterpillars of a Noctuid 

 moth,^ whose green and black colours harmonized abso- 

 lutely with those of the grass. These caterpillars were 

 hurrying about in all directions looking for more food, 

 and numbers of a brown " Ichneumon " were seen 

 depositing eggs in them. While piercing the larva with 

 its ovipositor the ichneumon grasped it firmly in its 

 mandibles, a habit which is shared by the stinging fossors, 

 who have adopted a somewhat more advanced kind of 

 parasitism. 



On Nsadzi were found, firstly by Fiske, the footprints 

 of a large Situtunga buck ; the importance of this has 

 been alluded to in the chapter on Glossina. 



We moved from Nsadzi on February 5th to a new 

 base on the east end of Kome, whence we intended to 

 examine the small islands of that neighbourhood. 



It was a most lovely voyage on a calm and clear day, 

 with much cloud of varied type and deep purple shadows. 

 We left Nsadzi at 7 a.m., and travelled past the tips of 

 the several peninsulae jutting out from the north shore of 

 Kome, and then down the beautiful channel between 

 Damba and Kome, where blue, pink and white water 

 lilies were in full flower. A small cloud funnel was seen, 

 giving warning of a short storm which came from 

 the east at about 4 p.m., and burst on us while we were 

 on Sanga Islet, but only lasted for half an hour. I was 

 much interested in this, because while I had been encamped 

 on Damba in 1911, only a few miles from Sanga, which 

 could be plainly seen (see map), I had never had an 

 afternoon storm there, but had noticed that the end of 

 Kome often caught rain which missed my camp. 



Sanga Islet was examined this day, and was found to 

 be amazingly interesting. It only measures about 100 

 by 60 yards, is very rocky and well covered with forest, 

 and shows abundant evidence of insularity.
