NOTES ON THE CRAMBUS FROM DEAL. V4 
viz., in the unicolorous wing, i.¢., no dark streak or shading, 
as in the Preston insect, and the first line showing only as 
a dot or spot on the central nervure of anterior wing, which 
is a frequent character in the Deal insect. There could be 
no doubt that our Blackheath and Deal insect was Hibner’s 
C. contaminellus. We then turned to Herrich-Schiiffer’s magni- 
ficent work, published about 1854 or 1855. ‘There the Preston 
C. contaminellus was clearly and well shown, its dark streak of 
blackish-brown shading running from the base, and filling up 
the space between the median and submedian nervures to what 
represents the first line (but which is a shading rather than a 
line), and which dark streak continues less directly to the second 
shade-line. 
It is thus very evident that both forms are known to con- 
tinental authors as Crambus contaminellus. Certainly to me 
they look two distinct species, but whether that is so, or that 
they are only two widely-divergent forms of one species, further 
investigation and a knowledge of the respective life-histories 
only can prove. Of course, if two species, Hubner’s figure, 
as representing the Blackheath and Deal form, must stand by 
priority as Crambus contaminellus, and a new name be found for 
the Preston form. 
With Mr. Stainton’s continental specimens he had one 
from Zeller; this was not so strongly marked as the Preston 
insect, but more nearly approached that form than the Black- 
heath, although it wanted the characteristic dark shade between 
the nervures. 
The figure given (Hntom. 53) of these is not good or 
characteristic of the Blackheath insect; the first line is much 
too oblique, and it is not bifurcate as there shown. I therefore 
append sketches to better explain my meaning. 
No. 1.—Anterior wing of male Blackheath contaminellus, male, 
picked, as showing the lines in their most distinct form. Colour, 
unicolorous warm brown. 
No. 2.—Anterior wing of ditto, female, picked, as showing narrow 
wing, produced tip, and broken first line. Colour, unicolorous grey. 
No. 3.—Anterior wing of Preston insect, showing streak. Colour, 
varied shades of warm brown and black-brown. 
All life-size. 
There is one very strong character in the Preston insect, to 
which I called Mr. Stainton’s attention, and he said at once that
