diverging outwardly and terminating on each side in a deep sinus 
for the reception of the antennze when extended forward ; the de- 
curved edges behind each sinus are much produced in the middle, 
curved inwardly, and form the posterior edges of the fovez ; the 
latter have between them a narrow longitudinal ridge; the rostrum, 
when viewed at the sides, has the appearance of being bidentate 
at the base; the antennz are inserted at the under sides of the 
rostrum near the base and within the fovez. 
Apion difficile of Herbst, of which I have specimens from 
Germar, is a distinct species, but closely allied to O. fuscirostris, 
and having the rostrum at the base, as described by Germar, bi- 
dentate. 
I have taken many specimens of this imsect in the Charlton 
sand-pits, and at Shirley Common near Croydon, from the broom 
(Spartium Scoparium) 1 October.

Apion Ulicis, Marsh., Kirb., Germ., Curt., Schonh. 
This insect is densely covered with silvery gray elongate scales. 
The female differs from the male in having the rostrum remark- 
ably longer, the antenne distinctly longer and more slender, 
and as a consequence the length of the articulations is extremely 
disproportionate im the sexes. The rostrum at the base above and 
beneath and its appendages are very similar to the preceding 
species, but it differs m having the foveze strictly at the base, 
with their external decurved edges considerably more dilated in 
the middle, and when viewed laterally it appears to be acutely 
bidentate ; the antennz are inserted at the under sides of the 
rostrum near the base and within the fovez. 
Very abundant in Yorkshire and in the south of England on 
the common furze (Ulex europeus) from February to November. 
Mr. George Luxford, by gathering (on the Ist of August) a num- 
ber of the unopened pods of the common furze, found several 
perfect insects of this species inclosed in nearly every one that 
he examined. 
3. O. Geniste, Steph. 
Apion Geniste, Kirb., Germ., Curt., Schonh. 
Densely clothed with silvery white and fawn-coloured elongate 
scales; the rostrum at the base is constructed like that of fusci- 
rostris, and with a similar process, but the decurved edges of the 
foveze in the middle are less produced, and consequently when 
viewed in profile it appears indistinctly bidentate. 
I found this insect abundant on the north side of the Lake 
House, Wanstead Flats, on Genista tinctoria in September, and 
it is the only locality for it near London that I am acquainted 
with; it appears to be very local and not frequently met with.
