but distinct, prominences on the head behind the clypeus, which are 

 scarcely visible in the type form ; H. fossor has lighter legs than the 

 >-ar. rectus, and only one small prominence on the head behind the 

 clypeus. 



H. marginatus and //. 1<i-vii~/a(us are often confused ; the latter i.s a 

 little larger on an average and is duller and more plainly pubescent, 

 with the markings longer (and moro 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 Iwigatus it is often occupied by more or less 

 long yellow markings ; in the latter species the second joint of the 

 antennas 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 tibiae 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, Eeiche; "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 Iritan- 

 nicut ; in both cases the specimens have been described as H. seri<:ans ; 

 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 '2\ mm. in length) and is somewhat differently 

 marked, the markings being yellow instead of red. 



H. cbsoletus, 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., is an 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 fusculus, 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 pulchellus and another (rather larger) from the London
