MAUNGWE 107 



to be ovipositing. Although this bush was abundant on 

 the neighbouring island, Dwanga Mto, this Lycaenid had 

 not been seen there.i It is a large white species 

 with fine hair-like wavy lines on the under surface. On 

 this island was found in a spider's web a second specimen 

 of the West African Lycaenid, first caught on Dwanga 

 Mto. Dwasendwe was markedly a " sj^ider island " ; and 

 Glossina was absent. 



On February 13th we moved camp to Kerenge Isle, 

 one of a group lying further eastwards. Fiske and I 

 started at 6-30 with four paddlers in the small canoe, as 

 we intended to visit sundry islets en route, leaving the big 

 canoes with kit and men to find their more laborious way 

 in their own time. 



At daybreak there were very threatening clouds, with 

 thunder to the south-east, and it seemed as if we must 

 get caught by a storm. The canoe men paddled furiously 

 to get to our first islet, and the small canoe seemed to 

 leap out of the water at every stroke, so that the un- 

 fortunate Fiske in the bows got very splashed, as there 

 was som^e swell from the distant storm. After one and a 

 half hours' paddling for the distance of six miles, we safely 

 arrived at Maungwe, a rock spit only about 80 by 30 

 yards in size, thickly covered with ferns, herbs, low bushes 

 and Ipomaea creepers with a few fig trees, on a fork of 

 one of which was an enormous nest, possibly of a heron 

 or a bird of prey. A very common weed, with 

 dull mauve flowers (Erlangea tomentosa, called by the 

 natives " Obutwatwa "), grew very tall and in dense 

 masses which sheltered a small bird with the habits of a 

 flycatcher, brown, with white throat and belly and brown 

 chest, which was subsequently found on minute islets 

 only, nearly always in masses of the " Obutwatwa." 

 It had a very sweet voice, and its song resembled part of 

 a nightingale's repertoire, so I dubbed it for reference
