being very local in this country. It used to be abundant at 
Birchwood. I have never seen it from North of England, but it 
is plentiful in Scotland. Biundularia appears to be common 
throughout England; and near Manchester assumes a smoky 
appearance, and is sometimes very dark, but not at all like true 
crepuscularia.” Mr. Doubleday writes again:—“‘ Feb. 5th, 1863. 
There is still a mystery about them. I am firmly of opinion we 
have two species in Britain. Here (Epping) we have nothing but 
biundularia ; they never have the ferruginous tint of crepuscularia. 
About Warrington biundularia occurs; but they get a dark 
smoky variety, totally unlike the Scotch crepuscularia. In the 
New Forest, Birchwood, &c., both species occur ; but crepuscularia 
is always out three weeks or a month before biwndularia.” 
“Feb. 23rd, 1863. Ihave always considered the peculiar rusty 
freckling as one of the most striking characteristics of crepuscu- 
larva, which seems to be a very local species in this country.” As 
Mr. Hellins says, in reply to a letter of mine reviewing the above 
extracts, ‘The Tephrosia question is evidently full of puzzles.” 
I will only add at present that, although I can see a difference 
between the double-brooded (crepuscularia) and the single-brooded 
(biundularia), itis not at all the same difference as Doubleday 
found between ‘‘ the pale” and “the dark” Tephrosia. I should 
say that crepuscularia is smaller, and has the second line followed 
by a more decided band of brown, while biundularia has blacker 
and more continuous lines, especially on the under side and on 
the hind wing. I should also say that the larva of crepuscularia 
is paler, almost putty-coloured, with yellowish spots on the 
claspers, while biwndularia is redder and darker, with white spots 
on the claspers. But we want more definite differences than 
these; and they will, I think, be found in the egg state, if at all. 
I should be much obliged to Mr. 'l'utt, or any other entomologist, 
if he will send me eggs of the March and July Tephrosia, 
especially the latter—G. A. SmaLtuwoop; Willington, Burton- 
on-Trent, May 15, 1886. 
Wuatr is CRAMBUS CONTAMINELLUS, Hiibner?—So much 
labour has been expended the past four months on this insect 
that I will not weary the readers of the ‘Entomologist’ with 
speculative matter, but simply place before them the following 
very interesting and conclusive extract of a letter from Mr. W. 
H. B. Fletcher, of Worthing, written to me last month :—
