AMATHUSIIN A. 71 
except when disturbed by another of the same species. In that case they fly with 
lightning rapidity, and in a most erratic way, and once I saw a Discophora dash 
himself to pieces upon an obstructive bough, through which he was apparently 
trying to fly. This is quite true, though it sounds improbable. They fly so fast 
that they generally get broken in the net by the force of impact; you may strike at 
them a dozen times as they pass you without inducing them to change their route” 
(Journ. Boston Soc. Nat. Hist. 1890, 60). Mr. L. de Nicéville states that: ‘“ All 
of them affect shade, fying but little unless disturbed, and resting near the ground 
with closed wings, usually amongst dead leaves” (J. A. 8. Beng. 1885, 43). As 
observed in N. Borneo, by Mr. W. B. Pryer, ‘ One or two species of not common 
Morphine are almost the only butterflies found in the deep gloomy forest which 
covers by far the great bulk of the country. Thaumantis comes next, perhaps, in its 
preference for heavy forest’? (Ann. Nat. Hist. 1887, 45). 
Foop Prants or CatirPitLAr.—The caterpillar of Discophora Celinde feeds upon 
the leaves of the Cocoanut Palm tree, and that of Dise. indica upon the Bamboo. 
The larva of Amathusia phidippus also feeds upon the Cocoanut Palm tree. 
CHARACTERISTICS OF THE AMATHUSIINA. 
The differential characteristics, between the Amathusiine and the American 
Morphine, are as follows :— 
AMATHUSIINA. 
Forrewine.—First subcostal veinlet only emitted 
before end of the cell. 
Second subcostal veinlet four-branched. 
Cell short, very broad, not extending to 
half length of the wing. 
No median vein spur, but the median and 
submedian with a slightly projected, approxi- 
mating tumid angle, that of the submedian 
in Zeuxidia developed into a slight spur. 
Hiypwine.—Cell either partially closed or entirely open, 
Cell area rather narrow. 
Male furnished with glandular patches of 
scales and tufts of hairs on various parts of 
this wing. 
Bopy.—Robust, thorax woolly. 
Antenne long. 
Abdomen sometimes with a glandular patch 
of scales on the base beneath, or with lateral 
tufts. 
Anal claspers of male elongate, narrow. 
Morpu ine. 
Forew1ne.—First and second subcostal veinlets free 
and both emitted before end of the cell. 
Third subcostal veinlet three-branched. 
Cell very long, narrow, extending to nearly 
two-thirds the length of the wing. 
Median vein witha basalspur. Submedian 
slender, no basal tumid angle. 
Hinpwine.—Cell entirely open. 
Cell area rather broad. 
Male. 
present. 
Glandular patches or tufts not 
Bopy.—Somewhat slender, smoothly scaled, 
Antenne short. 
Abdomen. 
present, 
Glandular pateh or tuft not 
Anal claspers of male broad, thick.
