little nearer the middle ; the markings, according to Kuwert, are reddish 
in H. flecuosus and yellow in H. femoralis, but this is not worth much 
as a character. I have only seen one specimen of the true H. femoralis, 
which was sent me by Mr. E. Waterhouse (without locality) and 
named by Herr Kuwert; it certainly looks very different from H. 
flexuosus, being shorter, smaller and duller, with the general colour 
dark and the markings hardly visible; H. flexwosus is apparently a 
rather common British species,. but it appears to be rarer on the 
continent, and Herr Kuwert says that he only possesses one specimen 
of it, from Morlaix; H. femoralis would seem to be rare in Britain, 
but there still appears to be considerable confusion with regard to it, 
and considerable doubt as to what really is the true H. femoralis of 
Kiesenwetter ; Herr Kuwert a short while ago sent me a specimen 
named H. femoralis from Pomerania, and now writes concerning it 
that he is inclined to believe ‘‘that the femoralis from Pomerania, 
which has the legs paler and is larger, may perhaps be the arenarius 
of Kiesenwetter.” With regard to 7. arenarius, I cannot discover an 
authentic British specimen ; I believe that light examples of flexwosus 
and levigatus are made to do duty for it; the following is Kuwert’s 
account of the species: “A little larger than femoralis. According to 
Kiesenwetter (I have no examples to refer to) in colour, markings and 
pubescence it comes half way between salinus and femoralis, but the 
colouring is brighter and the legs are entirely yellow ;’ the only 
locality he gives is Ireland ; as, however, I have pointed out (Vol. II. 
p. 386), Mr. Crotch came to the conclusion that the Irish specimens did 
not differ materially from femoralis ; I believe, therefore, that H. arena- 
rius should be regarded merely as a synonym of the last named species. 
Among the insects which I sent to Herr Kuwert are specimens named 
H. rectus, Wat., from Mr. Waterhouse’s and Mr. Champion’s collections ; 
these he is inclined to regard as a new variety or species, and proposes 
that they should be described by me as zntermedius,n. sp., as being 
intermediate between H. salinus and H. fossor ; I prefer to consider 
them as a variety of H. salinus; Kuwert was not, apparently, aware 
that the insect had been described, but, apart from this, there is a 
species of Kiesenwetter’s already in existence, named intermedius, which 
comes near hispidulus, Kies,* 
H. salinus is a rather large species (6-7 mm.), parallel, with bright 
yellow markings and legs entirely yellow ; the elytra are twice as long 
as together broad ; the thorax is short, with the sides strongly rounded 
and the margins more or less broadly yellow; the club of the antennx 
is somewhat long ; the colouring is variable, and the pubescence thick : 
the variety rectus differs in being smaller, with the antenne darker, 
and the legs dark instead of light ; it also has, in the male, two small, 
* Since I wrote the above I have received a letter from Herr Kuwert in which he 
says that he meant to propose “ zutermissus ”’ as the name, but wrote “ intermedius ”’ 
in error.
