80 THE ENTOMOLOGIST. 
I only found one which could in any way be regarded as a form 
intermediate between type and var. It would be interesting to 
know in how many of its many haunts this yellow form occurs 
regularly. 
The form has not been named, and the only named variety in 
this country appears to be Tutt’s ab. Nigra from a solitary example 
in the Dale collection. 
Brephos parthenias ab. flava, n. ab. 
Fore wings grey-brown without any trace of the reddish 
suffusion of the typical Parthenias. Hind wings a pale clear 
yellow without any trace of orange colour. Under surface pale 
yellow, markings as in the typical insect. Wimbledon Common : 
Type, ad captured March 27th, 1912, in my collection. 
MELANIC COSYMBIA (EPHYRA) PENDULARIA. 
By H. Worstey Woop. 
At a recent meeting of the London Natural History Society 
two collectors exhibited between them three examples of a melanic 
form of Cosymbia pendularia. Two of the insects were from the 
Oxshott district in 1915, the other from Haslemere in1911. The 
following is a description of this very distinctive form : 
Cosymbia pendularia ab. nigro-roseata, n. ab. 
Ground colour of all wings black, cross lines whitish, space 
between inner and outer cross-lines of fore wings reddish.
