Cardiophorus. | SERRICORNIA. 85 
clothed with very scanty greyish pubescence; head finely punctured, 
antenne black; thorax as long as broad, convex, narrowed in front, 
finely and thickly punctured, under-side with a longitudinal black 
streak in the middle ; elytra with punctured stri, interstices finely 
and thickly punctured; legs black, apex of tibie, claws, and more or less 
of tarsi, reddish. L. 7 mm. 
Stephens gives the following record of this insect, which is remarkable, as it has 
certainly not been taken for very many years :—‘‘ Rare, but widely distributed, 
occurring within the metropolitan district, in Norfolk, Somersetshire, &c.; Baron 
Wood, Cumberland, T. C. Heysham, Esq.; Windsor, Dr. Leach ; New Forest, 
L. Rudd, Esq. ; Collingbourne Wood, Rev. G. T. Rudd.” 
C. rufipes, Fourc. Somewhat depressed, black, upper surface 
clothed with very fine blackish pubescence ; head thickly and rather 
finely punctured, antenne longer in male than in female, black; thorax, 
as a rule, longer than broad, broadest in middle, very finely and thickly 
punctured ; elytra a little broader than thorax, with strong punctured 
strie, interstices convex, punctured; femora and tibiew reddish-tes- 
taceous, tarsi pitchy, the base of each joint and the claws being red. 
L. 53-65 mm. 
A single specimen was found by Mr. John Dunsmore in 1875 by sweeping rank 
grasses at Corkendale Law, the highest peak in Renfrewshire, about six miles from 
Paisley. Dr. Sharp, however, considers that further captures must be made before 
the species can be considered a native one.) 
CRYPTOHYPNUWS, [schscholtz. 
This genus is more characteristic of temperate and northern countries 
than perhaps any other genus belonging to the family ; it contains about 
seventy species, very few of which occur in tropical climates, although 
four or five have been described from Burmah, Borneo, Java, Para, 
&c.; the northern range of the genus, however, is very wide, as it 
stretches across Northern Europe and Siberia to Kamtschatka and 
Alaska, and is probably generally distributed over the northern hemi- 
sphere. The species vary considerably in size and appearance, and 
Thomson divides them into three genera, Cryptohyynus, Negastrius, and 
Zorochros, the first of which he classes with the Elaterina, and the two 
last with the Cardiophorina; the genus as a whole may be known by 
the spiniform posterior angles of thorax, and by the carina of the same 
angles being large and distinct and parallel to the side margin. Twenty- 
seven species are found in Europe, of which six occur in Britain; 
these may be divided as follows :— 
I. Thorax with the carine of the posterior angles 
ceasing before middle ; size larger. 
i. Thorax shorter, not rugose; elytra unicolorous, 
1. Upper surface and legs black; size smaller ; 
first joint of antenna shorter than third joint C. MARITIMUS, Curd.
