The Baron Dejean has placed Patrobus near to Pogonus in 
his Catalogue, an arrangement which I am disposed to adopt, 
since it appears to be natural ; I am therefore totally at a loss 
to account for the system proposed in the 44 Histoire Naturelle 
et Iconographie ,” and the 44 Families Naturelles” where Pa- 
trobus is included in a section with Panagreus. 
The anterior tarsi of the males in Patrobus having only two 
dilated joints, it is separated by that character from many of 
the Harpalidee ; and the straight anterior margin of the 
labrum, the slightly emarginate mentum, the more robust 
second joint of the internal, and the more slender terminal 
joints of the external maxillary palpi, are essentially different 
to Pogonus *. 
1. Patrobus rufipes Fab . — excavatus Payk. — var. b. Panz. 
34. 2. 
This insect has only the rudiments of wings, and the thorax 
is longer than it is broad, as shown at fig. 9. It is common 
in Norfolk, and Battersea Fields near London, where it is 
found under stones in moist situations from June to Sep- 
tember. 
2. P. alpinus Nob. 
I have little doubt that this is the Var. c. alatus of Gyllen- 
hal (v. 1. pars 2, p. 98), and although that learned author 
has recorded it as a variety only, I have considered it as dis- 
tinct, for the same reasons that were given for separating 
Clivina , where the two species are characterized precisely in 
the same manner. Both sexes have ample wings, the thorax 
is broader than long, the elytra are less deeply striated and 
of a castaneous colour, having the appearance of immature 
specimens ; but such was not the case, the elytra being per- 
fectly hard when they were captured. The sexes of this rare 
insect, the female of which is figured, I found under a frag- 
ment of rock near the summit of Craig- calloch, one of the 
Dochart Hills, together with specimens of Helobia Gyllenhalii 
(Plate 103), the 21st of July 1825. 
The plant, Saxifraga hypnoides (Moss Saxifrage), was ga- 
thered on the same mountain. 
* In the characters of Pogonus the internal maxillary palpi are represented as 
3-jointed, from the scape, to which they are attached, being more developed than 
usual ; but as that part is generally obsolete, it will be better to describe them as 
biarticulate.
