on Artemisia, tlie cases very closely resemble the excreta of the larger 
grasshoppers and this is possibly a protective device.) The cases of 
C. corrosicollis , Jac., are common on long grass and those of C. Pusaensis , 
Jac., on “ Jhau” ( Tamarix gallica), and the little larvae can be readily 
reared. Donnisthorpe has described the life- history of the European 
Clythra quadri-punctata, L., in Trans. Ent. Soc., London., 1902, p. 11. 
We reproduce his summary :— 
“ To recapitulate the 
foregoing facts : The life- 
history of Clythra quadri- 
punctata is briefly as fol¬ 
lows :—When the beetle 
has emerged from the 
pupa in the nest, it 
escapes with caution 
‘ feigning death,’ and 
holding on to twigs, when 
attacked by the ants. It 
then seeks its mate, 
and copulation takes 
place. The beetles are 
generally to be found on 
birch shrubs, the young 
shoots and leaves of 
which they eat, biting the 
top shoots right through. 
The female then seeks 
a tree or shrub above 
or close to a nest of 
Formica rufa, and drops 
the eggs on to the ground 
beneath. The eggs are co¬ 
vered by a case,or capsule, 
which is placed around it by the female, and consists of her own excre¬ 
ment. This covering is placed in position with the posterior tarsi, the 
egg being held in the depression of the abdomen. The covered egg 
looks exactly like a small bract, and is exceedingly like the end of a
