MTIOMU ISLET 121 



The beetles were on the Ipoinaea creeper, much of which 

 was stripped of leaves by the activities of them and their 

 larvae. One was brown in colour with rough surface ; ^ 

 the other smooth light brown, with very variable and 

 irregular black spots. ■^ 



On March 5th Fiske went to Entebbe on business, and 

 planned to meet me with supplies at the old camp on 

 Bulago on the 7th. 



I went to visit the small islets lying off the coast of 

 Damba, close to the camp. The first, Mtiomu, of spongy 

 brown rock, measures about 100 by 20 yards, and has a 

 fine sand spit at the southern end ; in the water at the 

 north end is a great grove of ambatch, which sheltered 

 abundant cormorants and weavers. For such a small 

 island the vegetation was extraordinarily varied ; except 

 for " Oluzibaziba " all the familiar bushes and flowering 

 plants of the lake shore were represented, so that several 

 species of butterflies might have been expected ; but 

 only T. telicanus, the cosmopolitan Lycaenid, was found. 

 Sunbirds and wagtails were seen, and particularly interest- 

 ing was the presence of the *' Nightingale flycatcher." A 

 small brown lizard was very abundant. Nephila spiders 

 were absent, also Olossina. 



Of Hymenoptera, several species of bees and Scoliidae were 

 seen, and also the black and yellow Sceliphron spirifex. 



The insular feature of Mtiomu Islet was the great 

 abundance of two large, conspicuous, aposematic beetles ; 

 one a black and canary yellow species of Cetoniidae,^ 

 evil smelling, and freely exposed on the flowers, the other 

 a Longicorn,* black with transverse red bands, which 

 fed on the green bark of sundry shrubs. 



Both of these are common insects, but were never 

 found elsewhere in such numbers. 



The adjoining Islet Tokwi is much smaller, consisting 



^ Anpidomorpha near moufletti. ^ Aspidomorpha near signatipcnnis 

 ' Pachnoda sinuata. * Ceroplesis signata {Lamiidae).
