694. Hidari irava, Moore. 



Hagen. Grose Smith. Staudinger. Snellen. Very common and 

 occurs throughout the year in ever following generations everywhere 

 where the cocoa-nut palm grows, on the leaves of which the larva feeds to- 

 gether with Amathusia phidippus, Johanssen (vide ante, p. 393). The 

 female always lays her eggs on young leaves, and the larvae are some- 

 times so abundant as to do appreciable damage to the palms by devouring 

 all the leaves. The larva is of a dirty green colour with subdorsal black 

 stripes and an ochreous head, and is hidden from view between two leaves 

 of the food-plant woven together. The pupa is reddish-brown. The but- 

 terflies are on the wing early in the morning and after sunset, and often 

 come to the lighted lamps. In the daytime they rest with folded wings 

 in dark places near houses. Once in 1892 all the cocoa-nut trees near 

 the Manager's house at Namoe Oekor were eaten up by the larvse, and 

 later hundreds of the butterflies took shelter during the day in the house. 

 None of them rested on the white-washed walls, but all on the dark 

 curtains and portieres. 



695. Hidari doesoena, Martin. 



H. doesoena, Martin, Einige neue Tagschnietterlinge von Nordost- Sumatra, pt. 1, 

 (Munich), p. 6, n. 4 (1895). 



The name given to this species by Dr. Martin is Dutch, and is 

 pronounced dusuna not desena. It has been described from six males 

 only taken in August near Bekantschan. 



696. * Hidari harmachis, Hewitson. 



Astictopterus harmachis, Hewitson, Ann. and Mag. of Nat. Hist., fifth series, 

 vol. i, p. 341 (1878). 



Hidari staudingeri, Distant, Ehop. Malay., p. 395, n. 3, pi. xxxv, fig. 25 (1886). 



Hewitson. Grose Smith. Hewitson described this species from a 

 specimen in his collection from Sumatra, and referred to another in 

 Dr. Staudinger's collection from Malacca. Mr. Distant described it as 

 a " new species " from a Malaccan specimen, also in Dr. Staudinger's 

 collection, probably the one Hewitson referred to. Distant also referred 

 to Astictopterus? harmachis, but failed to recognise it (1. c, p. 404). We 

 have not seen this species. 



697. Eetion elia, Hewitson. 



E. elia, de Nice'ville, Journ. Bomb. Nat. Hist. Soc. vol. ix, p. 396, n. 1 (1895). 

 Hewitson. Grose Smith. Butler. Kirby. Distant. Originally 

 described from Sumatra, where it occurs in our area at Selesseh and 

 on the outer hills from May to August.
