the scale, gradually receding towards its apex, and finally drying 
up. Sometimes there are as many as 300 eggs under one scale, 
and these, if watched carefully, may be seen to split at one end 
and the larva to escape. This latter is active and wanders about 
for a time, finally thrusting its proboscis into the orange, and re- 
maining fixed for life. It soon begins to grow and to secrete “lac” 
for its protection. The female appears never to lose her proboscis, 
but the pupa of the male is without it.

The various stages of the insect can be well seen with 1 in. objec-

ference to the diagrams will teach more than a description of the 
various organs, and to these, therefore, the reader is referred.
