110 A TOUR AMONG THE ISLANDS 



were so close that the spiders on those between others 

 were quite starved and their bodies very shrunken. 



Mantidae were not noticeably conspicuous ; the large 

 " Amajansi " grasshoppers were, and the beautiful king- 

 fishers which feed on them were also abundant. Acraeine 

 butterflies were not so abundant as on Ziro, indeed here 

 they were almost absent ; Lycaenidae were relatively so 

 abundant as to be the main feature of the butterfly fauna. 

 Of Hesperidae the large Gamia bucholzi was noted, and 

 Fiske found a shady bank where large numbers of a 

 Hesperid new to me were to be seen ; ^ it seemed to be 

 associated with a plant, probably of the Arum family, 

 which carpeted the ground here. Glossina only averaged 

 62 per boy-hour. 



We visited Lukalu Isle on February 16th, and found it 

 very interesting. About half a mile long, but narrower, 

 its greater part is a grassy plateau rising slightly in the 

 centre, with large beds of bracken on the slopes ; at the 

 east end are some high rocks with caves, and here are a 

 few big trees. One of these was like the common tree ^ 

 called " Ekirikiti " by the Baganda, but the spiky flowers 

 instead of being scarlet were of a rosy pink tint which I 

 had not seen before. 



From the eastern end of the isle stretches along the 

 south shore a narrow strip of dense bush ; the north shore, 

 however, is very different, there being a belt of thick cane 

 growing on sand, on which were marks showing that 

 crocodiles had lain there, and hippos had made tunnels 

 through the cane thicket. 



Five Enswa-swa were seen. The only birds that attracted 

 attention were a coucal and a grey plaintain eater ; the 

 " Kunguvu *' flycatcher was not seen. No Nephila spiders 

 were seen ; of butterflies Lycaenidae predominated ; 

 Lachnocnema bihulus was caught ; Acraea encedon was 

 in great variety ; the only Nymphaline seen was Precis 



^ Andronymua lemider. - Erythrina tomentosa.
