FAUNA SIMALÜRENSIS: 



The varieties virescetis Butler (Cat. Fabr. p. 259) and 

 niasiciis Jord. (Seitz, II, 2, p. 108) are not known to me. 

 The var. niasicus will resemble the most the new variety 

 squamosus by the density of the squamae on the fore-wings. 



2. Papilio Agamemnon Linn. 9- N*^. 4002. 

 Hab. Sinabang (Simalur). 



3. Papilio eurypylus Linn., nov. var. Heunii. (f. N^ 4003. 

 Hab. Sinabang (Simalur). 



The size, pattern and further habitus is that of P. evemon 

 Boisd., but the colour is darker 

 and the series of white spots 

 is narrower. The principal cha- 

 racteristic of this variety is to 

 be found on the underside of 

 tlie posterior-wing, where the 

 white spot in the cell is much 

 invaded by pure black. One 

 specimen from the island Nias 

 shows the same modification 

 though to a lower degree.

4. Papilio memnon Linn. 3 cT- Nos 4336—4338. 



Hab. Sinabang, Mata-n-amuren, Udjung Laukè (Si- 

 malur). 



These three male specimens are to be recognized from 

 all the other memnom in our collection, by the hind-wings, 

 these being covered with blue squamae as far as the cells. 

 Only near the outer-margin are blue-black conical spots 

 between the nerves. 



I have not bestowed a name upon this presumed variety, 

 P. memnon being so much variegated. Moreover some 

 transitional forms exist.
