DESCRIPTION OF CRAMBUS CANTIELLUS. 53 
With this series for comparison, I find that all the differences 
pointed out by me (Entom. 28) hold good, but that No. 3 wants 
modifying, as C. contaminellus does vary in its ground colour, 
though within very narrow limits. 
Still the differences are so great that no one, having seen the 
two species side by side, could possibly confuse them, and the 
mystery to me is how the new species has escaped detection so 
long. I am pleased, therefore, to confirm my previous opinion 
as to the novelty of the species, and beg to append the following 
description :— 
Exp. 83’’—11”. Head and palpi grey, the palpi very 
distinctly dusted with dark grey. Antenne simple in both sexes, 
but in the males thickened towards the base. Thorax and 
abdomen pale grey, the thorax in some examples much dusted 
with dark brown scales, and varying in depth of colour according 
to the colour of the anterior wings. Anterior wings variable in 
breadth and narrow for a Crambus, very acute at the tip, the 
female having the tip much prolonged. Colour very variable ; 
in males, generally pale grey, but varying to deep mahogany- 
brown and black; the females are much paler, and consist of 
two forms, pale straw-colour (which seems rare) and very pale 
grey (the type). 
The anterior wings have two dark transverse lines; the one 
nearest to the thorax, commencing just below the centre of the 
costa (not on it), is produced obliquely towards ss 
the thorax, till about half-way across the wing, 2 ee SZ 
when it is continued at a much more acute , de OT 
nterior wing (about 
angle (still pointing towards the thorax), until twice the natural 
it reaches the inner margin very near the thorax. °°” 
At the angular point of this line a very smali longitudinal line 
commences, and is continued for a short distance towards the 
hind margin. The second line is a doubly angulated line before 
the hind margin. It commences on the costa, about one-third 
from the tip of the wing, is sharply elbowed as soon as it 
commences, the elbow pointing towards the hind margin, and is 
again sharply elbowed in the opposite direction just above 
the anal angle. ‘The fringe of the fore wings is dark gray (not 
glossy); at the base of the fringe are a series of minute black 
dots running round the whole of the hind margin. Posterior 
wings grey, with very pale fringes.
