8, Var. nigro-varleyata, n. 



In this form the white on tlie fore wings of var. varleyata is obliterated, 

 the wings becoming entirely black. In the hind wings the white remains 

 (up to now), but is reduced iu area. 



I have bred five or six specimens the last year or two from 

 Huddersfield motlis, but it had previously been bred by Mr. L. W. 

 Newman iVom Ii\rnsley-bred motlis, and later by Mr. A. "VVhitaker also 

 from Barnsley-bred moths, but I know of no specimen having been 

 taken wild, or bred from a wild larva. 



9. Yar. lutea- varleyata, n. 



In this form the white parts of var. varleyata are replaced by yellow of 

 various shades. 



In my own specimens bred from Huddersfield moths, the shade is a 

 deep cream colour, but Mr. Kaynor has, by crossing wltli A'ar. lutea, 

 obtained a stronger yellow. The finest sjiecimen I know of is one in 

 which the yellow is very deep, and was either captured, or bred from a 

 wild larva, near Bradford. 



10, Yar. sparsata-hazeleighensis, n. 



This form is the var. Jiazeleiy/iensis, with the pale parts densely spotted or 

 blotched with intense black. 



I have bred several from wild Huddersfield larvae, the two finest — 

 both large females — having the hind wings almost entirely black. I do 

 not know the form from anywhere else.

Three British species of Eitmerus were described by Yerrall in his 

 volume viii. of " British Flies " published in 1901, and these include one 

 {E. sti'igatus Fall.) which has been found suiRciently destructive in the 

 larval stage to certain plants of economic importance to be classed as an 

 insect pest. On the Continent the larvae of what was considered to be 

 this insect have been recorded (more usually under the name of one or 

 other of its synon3'ms — aencns Mcq. or lunulatus Meig.) as living in
