134 A NATURALIST'S WANDERINGS 



country at Kotta-djawa. My favotiTite resort was the sunny 

 pathways, bordered by second growth forest of some size, 

 where many attractive Mussajndas, euphorbiaceous trees and 

 shrubs, and thick clumps of the aromatic and brightly Varie- 

 gated Lantana, were always in flower. 



The Lantana was one of the greatest favourites of most kinds 

 of insects ; beetles, bees, and butterflies were always present by 

 scores ; and I observed that they visited the different coloured 

 florets quite indiscriminately. Of the last the swallow-tailed 

 species — PapiNo brama, theseus, arycles, arjuna, and a lovely 

 black-and-white species which is known as Papilio saturnus 

 — were specially abundant, but difScult to secure, as they were 

 greatly persecuted by all the other species feeding on it — the 

 Pieridse and the dragon-flies being their worst enemies. 

 They constantly sailed round and round in a timid way, as if 

 watching for an opportunity to swoop in, but were often so 

 driven off that for half an hour at a time I have seen them 

 unable to make one successful visit. The beautiful tailed 

 Loxuras and Aphnasus were also in abundance, while Hypolymnas 

 anomala frequented the thick jungle, floating out at intervals 

 into the open. "This species offers the most remarkable 

 case known among butterflies of a reversal of the usual sexual 

 colouring, the male being always dull brown and the female 

 glossed with rich blue . . . The brilliant blue gloss causes the 

 female to resemble or mimic Euplsea niidamus" (Wallace). 

 Mr. Butler has shown me in the British Museum, however, 

 males with nearly as much blue as the females. It is 

 singular that no male of this species is yet known from Java. 

 Specimens in the British Museum, named by Mr^ Wallace as 

 males of Anomala, are not from Java. Undoubted males from 

 Malacca and Borneo have broad patches of blue towards the 

 border of the front wings. The female Anomala from Java has 

 more blue than the specimens of the same sex from Borneo, 

 and it is not improbable that the Java male may have more 

 blue than the Bornean. What appears to be a female, named 

 Hypolymnas wallaceana by Mr. Butler from ' India,' corresponds 

 with the male H. anomala (of Wallace's description) in the 

 British Museum from Borneo. The Euplsea which these species 

 mimic is common to Indo-Malasia.
