INSKCTA. 
or of a reversed cone; one of the two spurs of the internal extremity 
of the two anterior tibiee is inserted higher than the other, with a 
notch between them. The four or three first joints of the anterior 
tarsi of the males are in general hut slightly dilated. The palpi are 
never elongated. They are shore Insects, and peculiar to Europe 
and Siberia. 
Sometimes the labrum is very short, transversal, and terminated 
by a straight line. The last joint of the exterior palpi is almost obco- 
nical, thicker and truncated at the extremity. The mandibles ad- 
vance considerably beyond the labrum. The anterior tarsi of the 
males are sensibly dilated.

In some of them, and the lasgest — Blethisa, Bonelli — the thorax 
is wider than it is long, plane, bordered laterally, almost square and 
slightly narrowed towards the posterior angles. 
Here, the three first joints of the anterior tarsi of the males are 
strongly dilated and cordiform. They are the Pelophilce of De- 
jean *, 
There, the four first joints of the anterior tarsi of the males are 
slightly dilated — they form the Blethisa, Dejean f. 
In the others, the thorax is at least as long as it is wide, convex, 
cordiform and truncated. The body is proportionably more convex 
than in the preceding subgenera. The four first joints of the ante- 
rior tarsi are slightly dilated in the males. These latter alone com- 
pose his genus Elaphrus. 
E, uliginosus ; C. uliginosus. Fab.; Elaphrus riparius, Oliv., 
Col. II, 34, I, 1, A — E. About four lines in length, of a black- 
ish bronze, with numerous puncta ; little depressions or fossulse 
on the front and thorax, and others with a violent bottom and 
elevated contour joined to each other on the elytra ; tarsi bluish- 
black ; tibiae sometimes of the latter colour and sometimes rus- 
set. These latter individuals have been considered as a distinct 
species — cupreus — by M M. Megerle and Dejean. It is rare 
in the environs of Paris, but common in other parts of France, 
and in Germany, Sweden, &c.

the uliginosus; above, very finely dotted with dead-cupreous, 
mixed with green ; circular green impressions with papillated 
centres arranged in four lines, and a polished, shining cupreous 
spot on each elytron near the suture. Common in the environs 
of Paris 
Sometimes the labrum is almost semicircular and rounded ante-
