ERNEST GREEN has since then been so kind to describe 
as: Lecanium opimum nov. sp.') This scale infested several 
plants of Cassia fistula L. in my garden. The moths I 
reared were much larger than the measurements given by 
Dr. ZEHNTNER (l.c.), but agreed fairly well in size and 
„exactly in design and colour with the drawing given by 
Dr. KONINGSBERGER. It has been identified by Sir G. F. 
Hampson as Zublemma rubra HAMPSON. °) 
The caterpillar with its covering figured by Dr. KONINGS- 
BERGER (l.c. fig. 28) is an exceptionally small specimen, as 
most of those I found were nearly four times as large; 
but I also met with very small ones. I presume that, same 
as with many other insects and specially Lepidoptera, the 
abnormally small specimens are starvationforms. If a larva 
(caterpillar) has only a limited, insufficient amount of food 
at its disposition, it pupates all the same, but at an earlier 
date, and the forthcoming imago will be a pygmy. 
The figure given by Sir HAMPSON (Cat. Lep. Phal. Br. Mus. 
Vol. X PI. CLIV fig. 5) from a d specimen from Sikhim 
shows very little resemblance to my specimens. The expanse 
of wing is given there as 16—18 mm., whereas my biggest 
imago measured 28 mm. 
Sir Hampson, whose attention I drew to these facts, 
answered me, that his figure was not very good, but that 
the specimens I had sent agreed in the markings of the 
fore wing exactly with the specimen from Sikhim, and 
although the moths from Java were much larger, they 
represented without doubt the same species. 
On the accompanying Plate 5 fig. 1. and 2. are full- 
sized drawings of a d of Eudlemma rubra from Java. 
Evidently the caterpillar of this moth lives on different 
species of Lecanium, as it has been observed by others as
