20 Mr. James Edwards’ Synopsis of 
claval suture, whitish; occasionally all the nerves are pale. Frons 
punctato-rugulose, distinctly impressed across the top. Crown 
about as long as the pronotum, longitudinally striate, reflexed at 
the apex, its middle keel exceedingly fine. Pronotum rugulose in 
front, transversely striate behind. Elytra coriaceous, a little longer 
than the abdomen, transversely rugulose, nerves raised. Breast 
and abdomen black. Legs pale. Length, 5—6 mm. 
2. Upper side dirty greyish or greenish yellow, more or less 
closely speckled with black, and frequently having a few pale spots 
arranged in an irregular band-like manner across the elytra, the 
nerves sometimes chequered with black and pale. Crown about 
one-fourth longer than pronotum. Elytra as long as the abdomen, 
the apical areas sometimes filled up with fuscous, so as to give that 
part a chequered appearance. Length, 6—8 mm. 
Common everywhere. 
Var. a. Upper side reddish yellow. (9). 
Var. 6. Upper side varying in colour from red-brown to almost 
black. (9). 
On the salt-marshes at Wells, Norfolk, in August, 
1883, under Obione portulacoides, I fell in with what I 
can only regard as a remarkable race of this very 
variable species ; the males are distinguished by having 
the upper side very pale yellow-brown with a greenish 
tinge, and exceedingly finely irrorated with fuscous, and 
the shape of the crown in extreme examples is decidedly 
sublunate; the range of variation in the females, how- 
ever, extends to the ordinary speckled form. Both sexes 
appear distinctly narrower than typical nervosus, but I 
have not been able to discover any structural differences 
on an examination of the male genitalia. 
A. carinatus, Stal (=variegatus, Fieb.) has been 
recorded as British, but a specimen lent to me by 
Mr. Douglas, and labelled by Dr. Signoret, is a dark 
example of the speckled form of nervosus 9. The true 
carinatus, which is said to resemble nervosus 2, should 
have the crown tricarinaie in both sexes.
