950 Mr. J. C. Kershaw and Mr. Frederick Muir on the 
as the African species A, puncticosta and confinis. The bare 
ege-case also places it with these species, but its simple 
nature and the absence of any eggless membrane to act 
as attachment to the leaf indicate an affinity to the genera 
Cassida and Laccoptera. 
The larva and imago generally feed on the under-side of 
the leaves. If the pupz be kept in a light-proof box the 
bright or metallic colours do not appear in the imago. 
2.—Aspidomorpha micans, Fab. 
This species generally lays its eggs in batches of two, but 
sometimes three and even four eggs are placed together. 
Each egg is attached to the usual shaped Cassidid egg- 
membrane which has a slight thickening longitudinally, 
a midrib, and is doubled back over the egg. In captivity 
the first egg is sometimes attached direct to the leaf, but 
more often an eggless membrane is first attached to the 
leaf and the eggs laid in it. The second egg is placed to 
one side—+.e. the right—of the first, the third is placed 
upon and between the first and second, and the fourth, if 
present, to the leaf of the first. In captivity the egg-case 
is sometimes partly covered with excrement, but we have 
never found one so covered in the field. 
During the larval and pupal life the skins are carried on 
the long posterior spikes, but no excremental matter is 
attached to them; occasionally during the first instar 
small pieces of excrement are carried at the end of these 
posterior spikes. 
A pair in cop. at 10 a.m on the 5th September produced 
two egg-cases by 4 p.m. These remained in the egg state 
seven days, in the larval state nineteen days, and in the 
pupal state six days. 
Both by the egg-case and larval appendage this species 
falls into the African Aspidomorpha group. 
3.—Laccoptera chinensis, Fab. 
The egg-cases of this species contain two, three and 
sometimes four eggs, and are generally, but not invariably, 
covered with excremental matter. This covering is variable 
in size, sometimes covering the entire case, at other times 
being only a small patch in the middle of the membrane. 
The first egg is attached direct to the leaf and the 
membrane turned back in the usual way. 
Soon after the larva hatches it attaches a small piece of
