694. Hidari iraya, 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 wiug 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 larvae, 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.

(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.

Hidari standingeri, Distant, Rhop. Malay., p. 395, n. 3, pi. xxxv, fig. 25 (1886). 
Hewitson. Grose Smith. Hewitson described this species from a 
specimen m 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.

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.
