in Langkat, and Kotta Lembaroe iu Deli. It settles on trees not 

 very high from the ground with widespread wings, and behaves on 

 the wing like an Euthalia. 



180. Hypommnas bolina, Linnaeus. 



Snellen. Hagen as bolina and jacintha. Wallace. Staudinger as 

 bolina, var. jacintha. Distant. Extremely variable in the female sex, 

 many of them being of the form named jacintha by Drury. But none 

 of the forms described by Cramer from Java which are more or less 

 richly marked with oehreous on the upperside, such as iphigenia, melita, 

 alcmene, antigone, and proserpina are found in Sumatra. In Deli it is 

 rather rare, and prefers low elevations, not being found higher than 

 Namoe Oekor. It is more plentiful near the sea, as at the Saentis 

 Estate and at Mabar Dr. Martin could obtain one or two specimens 

 nearly every day. Only in December, 1892, and January, 1893, it 

 appeared in large numbers and all varieties of the female near Bindjei, 

 but in the following year there was not a single specimen to be seen. 

 It does not frequent forests, but is found on roads, in gardens, and 

 near houses. 



181. Htpolimnas anomala, Wallace. 



Grose Smith. Snellen as antilope. Hagen. Semper. The H. anti- 

 lope of Cramer described from Amboina appears to be a distinct species, 

 and is recorded by Wallace from Amboyna, Ceram, and Bouru. In our 

 area H. anomala becomes year by year more scarce, in correlation with 

 the disappearance of the foi'ests. It does not occur at higher elevations 

 than Bindjei. Is a highly mimetic insect, as the males very closely 

 resemble on the wing the brown species of Euploea, such as E. moorei, 

 Butler, and also settle near forest roads like Euploeas with folded wings. 

 The female is trimorphic ; the first form has the upperside richly 

 glossed with blue, and mimics the male of Euploea Knnaei, Moore ; the 

 second form is dull brown, lacking the blue coloration altogether, is very 

 similar to the male, only duller and larger, and mimics the brown 

 Euploeas ; the third form has along the outer margin of the hindwing on 

 both the upper and undersides a series of marginal white streaks be- 

 tween the veins, and may be taken on the wing for E. pinwillii, Butler. 



182. Hypolimnas misippus, Linnasus. 



Snellen. Hagen. Distant. The female in Sumatra is of the 

 form of diocippus, Cramer, and is a beautiful mimic of Danais chri/sip- 

 pus, Linnaaus. The form which mimics Danais klugii, Butler, and 

 occurs in India and Africa, is not found in Sumatra, neither docs it
