but distinct, prominences on the head behind the clypeus, which are 
scarcely visible in the type form ; H. fossor has lighter legs than the 
var. rectus, and only one small prominence on the head behind the 
clypeus. 
H. marginatus and H. levigatus are often confused ; the latter is a 
little larger on an average and is duller and more plainly pubescent, 
with the markings longer (and more colon-like (colon-artigen) accord- 
ing to Kuwert) on the disc; in marginatus they are smaller and more 
often form spots ; the scutellary region appears to be usually dark in 
marginatus, whereas in levigatus it is often: occupied by more or less 
long yellow markings; in the latter species the second joint of the 
antenne ends in a whitish tuft of hairs, of which the longest reach the 
apex of the club; both these species have the hinder angles of the 
thorax rather distinctly margined. 
The following is Kuwert’s description of H. britannicus -— 
H. britannicus, n. sp.: Thorax plainly broader than the elytra, 
the latter with obscure red spots, and with thick yellowish pubescence ; 
thorax black with shorter and less thick pubescence, with a distinct 
red central line and badly defined reddish sides, very strongly rounded 
and widened in the middle and a little narrowed in front, Male with 
the clypeus raised into a prominence on its anterior margin, and with 
the intermediate tibia strongly widened beneath. Legs and apex of 
abdomen reddish. L. 2 mm. 
Described by Herr Kuwert on a single male obtained through M. 
Bellier de la Chavignerie, labelled ‘ Anglia, Reiche ; ” apparently, how- 
ever, locally common in Britain ; it has been taken in numbers by Mr. 
Lennon near Dumfries, and I have received specimens from Mr. Ben- 
nett of Hastings ; the latter are considerably darker, and I am not sure 
that they ought not to be referred to another species; Herr Kuwert, 
however, has named the specimens from both localities as his britan- 
nicus ; in both cases the specimens have been described as sericans ; 
I have not seen a British specimen answering to the description of the 
last named insect, although it very probably occurs ; it is larger than 
H. britannicus (being 24 mm. in length) and is somewhat differently 
marked, the markings being yellow instead of red. 
#1. obsoletus, Curt., is one of our most distinct species by reason of its 
rather large size (usually about 5 mm.) and coarse punctuation, and 
small, but plain, lighter markings. 
H, fusculus, Kies., isan extremely local species, but occurs abundantly 
at Luccombe Chine, Isle of Wight, on wet and muddy places at the 
foot of the cliffs about thirty feet above high water mark; I sent a 
specimen to Herr Kuwert taken by myself at this locality and he named 
it pulchellus, Kies. ; a specimen, however, taken by Mr. Champion at 
Sandown, a few miles from Luccombe, is returned as JSusculus, and I 
believe that both insects belong to the same species ; another specimen 
of Mr. Champion’s, from Dr. Power’s collection, without locality, is 
returned as pulehellus and another (rather larger) from the London
