106 A TOUR AMONG THE ISLANDS 



by the natives was much more plentiful than on other 

 islands hitherto visited. 



Regarding butterflies, the most noteworthy feature was 

 the abundance of the large Hesperid Rhopalocampta 

 forestall, hitherto not encountered on the small islands ; 

 its near ally, the beautiful Rh. chalybe of Sanga Isle, was 

 not seen here. The single Papilionine (see table, p. 125) 

 was P. leonidas, whose Danaine model Meliyida petiverana 

 was also seen. Acraeines were so extraordinarily scarce 

 that I only caught one specimen, and only one other 

 species was seen. Nymphalines included Salamis, which 

 was very abundant, Pseudacraea eurytus forms hobleyi 

 and terra, Ps. lucretia, Euralia dubia, two Charaxes, 

 a Neptis, and H. misippus and C. cardui, neither of which 

 occurred on other islets of this group. 



A curious Lycaenid was found here, a large grey species 

 with angulated wings. ^ A feature of the island fauna was 

 the number of long narrow cases of the larvae of a Psychid 

 moth, attached to tree trunks. 



Glossina was almost absent ; the nine fly boys could only 

 catch four males and a female. 



The third island of this group, Dwasendwe, was 

 visited on February 10th. 



It is covered everywhere with forest or overgrown 

 plantations ; almost everywhere the shores are rocky ; on 

 the north-east there is a dense bank of ferns. The main 

 insular feature of Dwasendwe was the great abundance 

 of the Aletis larva first met with on Sanga ; these had 

 defoliated the food plants over a large area. 



Of butterflies, Acraeines were again very scarce, one 

 Planema and one small Acraea only were seen ; of Hes- 

 peridae the large Gamia bucholzi, with mottled underside, 

 was noted : a Lycaenid was found which was never met 

 with on any other island, and was apparently associated 

 with the '' Omukwakula" bushes on whose flowers it seemed 



^ Aslauga purpurascens, Lipteninae.
