The following varieties are paler than the type : — 
Cymatophora or F. a scotica Tutt and flavistigmata Tutt ; 
Tapinostola fulva Hb. ^ ochracea Tutt and 8 pallida St. ; 
Xylophasia Zollikoferi Frey a pallida Tutt ; X. rwrect F. a 
urgentea Tutt, /3 ochrea Tutt and 8 fiavo-ruga Tutt ; Miana fasciun- 
cula Haw. /5 cana Stdgr. 
Some of the following varieties do not fall into either of the 
above groups, whilst the position (so far as can be learned from 
the description) of others is somewhat doubtful : — ■ 
Acronycta menyanthidis Vw. /? scotica Tutt (pale ?) ; Tapinostola 
fulva Hb. e pygmina Haw. (pale ?) ; Apamea gemina Hb. a 
rufescens Tutt_, intermedia Tutt and a remissa Hb. ; Charoeas 
graminis L. agramineus Haw., ^ tricuspis Esp., 7 rw/<x Tutt 
and 8 rufo-costa Tutt. 
From these lists it will be seen that considerably more than 
half (28 to 18) of the varieties mentioned are melanochroic (in the 
sense in which that term is used), thus supporting the statement 
made above, that in North British specimens there is usually a 
tendency to a darkening of the coloration. 
We look forward with interest to the continuation of Mr. Tutt's 
valuable work.
