ANIMALS INJURIOUS TO FARM AND GARDEN PRODUCE. 9 



Fowler (op. cit.), quoting from Chapius and Candeze, states that 

 " when the time arrives for the change to the pupa the larva attached 

 itself to a point of the leaf." Most of the larvae I had pupated on 

 the under side of the leaves close to the mid-rib, others attached them- 

 selves to the glass disc covering the breeding cage, whilst a few 

 pupated on the floor and sides of the cage. 



The imagines appeared on July loth and nth; all appeared 

 very inactive, and if touched immediately fell off the leaves as if 

 dead, and remained in this state for some minutes before attempting 

 to walk again. I was unable to satisfy myself that the beetles 

 themselves fed upon the leaves.

Fowler (op. cit.) states from Chapius and Cancleze that the 

 larvae " are covered with a glutinous matter, which is secreted from a 

 retractile nipple placed on the upper surface of the anal segments ; the 

 softness and mobility of their integument enables them to. cover their 

 entire body with this substance ; it partly serves as a protection 

 against rain and heat, but its chief use is in the formation of the 

 cocoon in which the insect undergoes its metamorphoses ; when the 

 time arrives for the change to the pupa state the larva attaches itself 

 to a point of the leaf and thickens the glutinous matter which covers 

 it, and then contracts its body so as to gain in breadth what it
