yellow with deep shining black (as if varnished) spots. The males 

 are very fond of flowers, on which they settle with closed wings like 

 an Euplcea. It is almost certain that all the species of Delias feed 

 in the larval state on Viscum and Loranthus which are found everywhere, 

 and as there are species of Loranthacege occurring also on Rhizophores 

 (Mangrove trees) on the sea beach, the strange fact which haa 

 been observed by Dr. Hagen that D. parthenope, Wallace, is the only 

 butterfly found in the Mangrove forests, is explained.

Hagen as hageni and simanabum. Both D. hageni and D. danala, 

 de Niceville, occur only at the elevation of Soengei Batoe and on the 

 Central Plateau ; they are most numerous from June to August, during 

 the other months of the year but few specimens have been obtained. 



531. Prioneris clemanthe, Doubleday. 



Hagen. Rare in our area, a few specimens only from near Selesseh 

 including one of the excessively rare females. Like Hebomoia burneensis, 

 Wallace, it is more common on our western boundary, as the Gayoe 

 collectors have brought in males in large numbers. Flies from January 

 to June, but is most abundant in February. 



532. Prioneris hypsipyle, Weymer. 



P. hypsipyle, Weymer, Stet. Ent. Zeit., vol. xlviii, p. 12, n. 10, pi. i, fig. 1, male

Hagen as hypsypule [sic]. My female differs from the male only 

 in the forewing being blunter, less produced at the apex. Dx*. Martin
