Fig. 8. Transverse section through the 

 mid-gut of a larva of Lithophane lapidea 

 infected with a cytoplasmic polyhedrosis. 

 Note the polyhedra filling the lumen of the 

 gut. (Magnification: X 650.) 



Fig. 9. Larvae of Phlogophora meticulosa killed 

 by a cytoplasmic polyhedrosis. Note the accumu- 

 lations of polyhedra showing through the skin.

Fig. 11. Part of a section through a cytoplasmic 

 polyhedron from a larva of Arctia caja. Note the 

 apparently composite virus particles. (Magnifi- 

 cation: X 57,000.) 



Fig. 10. Section through a cyto- 

 plasmic polyhedron from a larva of 

 8. ligustri; it is not easy to see the 

 virus particles (compare Fig. 19).
