Polyhedral diseases are known to occur .in. nature in the caterpillars 

 of the following Lepidoptera : — Hemileuca niaia, Dru., Apantesis 

 virgo, L., Cirphis {Leucania) unipuncta,, Haw., Agrotisunicolor (Noctua 

 chndestina, Harr.), Phytometra {Autogmpha) hrassicae, Riley, Lymantria 

 [Porthetria] dispar, L., L. monaclia, L., Hemerocampa {Orgyia), leucosti- 

 gma, S. & A., Malacosoma americana,~F., M.disstria, Hb., Bombyx 

 mori, L., Phryganidia californica, Pack., and Colias philodice, God. 

 Several forms of disease can he distinguished, each of which is characr 

 terised by a special type of polyhedra. The size of the polyhedra 

 varies very considerably in different species of insects, but there is a 

 marked similarity in shape. Wilt disease of gipsy moths, army worms, 

 etc., is caused by a filterable xiirus and it is beUeved that the polyhedra 

 arise as a reaction against the invasion of this virus. The latter 

 disintegrates the nuclear material of certain tis;Sue cells in such a way 

 that polyhedral bodies are .synthesised frpni the .disintegrating proteins. 

 The polyhedra are therefore not living organisrps wMch are responsible
