Distribution.—This insect has a wide distribution. Dr. Modig- 
liani reports it from Sumatra: Siboga, Baligha, Pangherang- 
pisang and Pedang (ref. 6). Nothing about the food-plant of this 
insect in these localities is mentioned. In India it is a pest of 
the Rice plant. 
Weise has sunk Motschulsky’s species cyanipennis as a 
synonym of armigera, Oliv. (ref. 7). .Comparing Motschulsky’s 
description (ref. 2) with Olivier’s, and also Baly’s, I find no 
reason why cyanipennis, Mots. should be considered as a synonym 
of armigera, Oliv. Motschulsky writes: ‘‘ Corslet assez lisse, sans 
epines dorsals; elytra fortement ponctuees avec quatre efines sur 
leur milieu.’’ Olivier in his description of armigera says: ‘‘Le 
corcelet est armee de cinq epines de chaque cote; la quatra 
anterieures ont une base commune; la cinquieme la plus courte 
de toutes, est places un peu au-dila. Les elytres sont d’un bleu 
fonce luisant; elles sont des points enfonces et un grand nombre 
d’epines.’’ Baly’s description of aenescens (ref. 4) runs as fol- 
lows:—‘‘ Thorace rugoso-punctato lateribus anti medium spinis 
quatuor, basi connatis et pone medium spina unica armatis; ely- 
tris anguste oblongis, fortiter seriato-punctatis, spinis validis 
triseriatium dispositis instructis.’’ . 
From the above it is evident that cyanipennis, Mots., cannot 
be a synonym of armigera, Oliv.; cyantpennis has no spines on the 
thorax and only four spines on the elytra. In his description 
I have italicised these portions. Avmigera, Oliv., and aenescens, 
Baly, the descriptions of which agree well, both have five spines 
on the thorax and a great many on the elytra. In the absence of 
any reason from Weise for sinking cyanipennis, Mots., I consider 
it necessary to point out that Motschulsky’s description does not 
warrant it. ‘The type of cyanipennis is supposed to exist in the 
Museum of the University of Moscow.
