PARASITIC FUNGI. 



In addition to above the following have also been observed : — 



Melanotaenium endogenurn. On Galium verum, rough pastures, Lang- 

 ton : Downs above Lighthouse, in some quantity ; and about 

 the quarries, Swanage. This is a black fungus, and usually spreads 

 and destroys the plant before it can flower. 



Puccinea Thesii. On TJiesium humifusum, Downs above Lighthouse, in 

 some quantity; also in the quarries, Swanage. ("Rust Fungus.") 



Puccinea Malvacearum. On Malva sylvestris, Creech; Langton; Swan- 

 age. Gardeners know this as " Hollyhock Disease." 



Trochila ilicis. On fallen Holly leaves, Creech, and Studland Woods. 



Erysiphe (Oidium) Euonymi=japonicce. Enonymus " Mildew." Much 

 too frequent on these shrubs about Durlston and Swanage. For 

 description and illustration vide Proceedings B.N.S.S., Vol. III., 

 p. 81. 



Septoria Euonymi-japonicoz (" Spot Fungus "). On fallen leaves of 

 Euonymus, which is largely planted at Durlston. New to Britain. 

 While, however, the preceding fungus is a summer state, this one 

 matures during winter and spring. (See illustration and note by 

 Mr. J. F. Rayner F.R.H.S.) 



Note. — In preparing these papers for publication a good deal of matter 

 has been excised, in fact the section dealing with the Ferns has been omitted 

 altogether. On the other hand a few subsequent finds have been included.

The Significance and Possible Origin of the Colour 

 Pattern of the Puss Caterpillar. 



Joseph Neale, B.A., Bournemouth. 



(Read before the Zoological Section, January 14th. 1915.) 



STUDIES in outdoor rearing of Caterpillars in their natural 

 ^ habitats suggest that it may be of general interest to call 

 attention to the correlation of posture and colouring to environ- 

 ment in the Puss and Kitten larvae, and to enquire if there is any 

 hint of how their peculiar pattern has originated. 



The Puss, the largest and most striking of the group, will 

 serve as type of all. Its pattern is apparently unstable — two 

 specimens are seldom quite alike either in tone or distribution of 

 colour — the same batch of eggs will produce larvae with mark- 

 ings ranging from close approximation to Poplar and Sallow 

 Kittens as figured by South, to the typical V inula patterns accur-
