(2) A flap may be cut out of the edge of the leaf and folded over, 



pupation taking place inside the flap. 

 Fig. XVI shows this. 



(3) A single leaf may ho rolled up longitudinally, the cocoon 



being placed inside the roll. 



One-half of the leaf may be thus rolled up, or in the case of a 

 large leaf only a portion of the edge rolled, in, or, finally, 

 in the case of a small leaf both sides may be rolled in 

 towards the midrib, the larva pupating along the midrib. 



To make the shelter secure, the hollow end of the roll is some- 

 times closed by having the surface of another leaf fastened 

 tightly over it. 



Fin-. XXI shows a leaf with both sides rolled inwards and 

 Fig. XXII a leaf with only one edge rolled in. 



(4) The surfaces of two leaves which overlap one another, may be 



joined together, pupation taking place between them. 

 Fig. XXIII shows this. 



(5) Several small leaves may be tightly bound together in a 



variety of ways, the cocoon being made inside them. 

 Fig. XXV shows this. 



43. When pupation takes place on the leaves of the plant on which 

 the larvae feed, the methods of constructing the shelter for the cocoon 

 and the ordinary larval shelter are practically identical, and sometimes, as 

 noticed abova, pupation takes placa in the larval shelter, all openings of 



course being closed up. 



44. The cocoon is of white silk, somewhat roughly woven, the threads 

 being further apart than is the case in the cocoon of Pyramid* 



45. When the larva pupates in the soil, a pupal chamber is made of 

 silk and bits of earth bound together. 



Fig. XXVI shows two such chambers. 



46. It is perhaps as well to draw attention here to the fact that 

 Pyramid has been called the " Teak Leaf-roller." This appears to be a 

 misnomer, due I believe to a confusion of Pyramid with Hyblced. 

 Pyramid does not appear to merit the appellation, either on account of 

 the habits of the feeding larva, or on account of the way in which 

 the pupal shelter is constructed, whereas the name might well be 

 applied to ITyhhra for both reasons.
