Carlisle larvte, not one of these was ichnenmoned, and were 

 very forward, being three-quarters fed when received end of 

 March, All emerged well, but the quantity at disposal being 

 small, most were spoilt in obtaining pairings and ova. 



Mr. Newman also exhibited {y) a long series of Notodonta 

 chaonia bred from ova from Perth parents, both of the typical 

 dark brown form. The series showed a great range of varia- 

 tion, a good percentage following the parents ; a large percen- 

 tage of intermediate forms, and about 15 % with the white 

 band on fore-wings well defined ; (A) a series from New Forest 

 parents, this form showing a strong contrast to the Perth race, 

 the ground-colour being much whiter and the white on fore- 

 wings much pronounced, bringing out the lunar spot con- 

 spicuously ; (t) a series from a pairing obtained from Perth 



9 and New Forest c^, the experiment producing a very 

 mixed series, the general tendency being to follow the dark 

 Perth 5 parent : very few (three or four) l)eing as light as the 



^ parent ; {k) a series from an Isle of Wight wild captvued 9 > 

 this form being quite distinct from that of the New Forest, 

 having a yellowish tinge, and the ground-colour being about 

 intermediate between the darkest Perth and lightest New 

 Forest forms. 



Mimetic Relation of Nychitona and Pseudopontia. — 

 Dr. F. A. DiXEY exhibited specimens of XycJutona medusa, 

 Cram., and Pseudopontia paradoxa, Feld., observing that a 

 former suggestion of his as to a mimetic relation between them 

 (see Proc. Ent. Soc. Lond., 1906, pp. Ixix-lxxi) had been con- 

 firmed by a letter lately received from Mr. S. A. Neave, at 

 present in the Congo State, who wrote that the two forms 

 " inhabit exactly the same localities and are barely distin- 

 guishable from each other on the wing."
