418 Mr. J. Walton on the genus Anthonomus. 
which are constant. I have a Swedish insect sent me by Schon- 
herr as Ant. Ulmi var. 7, which undoubtedly belongs to this spe- 
cies, and which it is evident he has also confounded with the pre- 
ceding. 
Exclusively of colour, it may at once be distinguished by 'a 
comparative examination of the following eharaeters : the rostrum 
is shorter, thieker, and the antennje inserted nearer the apex ; 
the tooth of the anterior femur evidently shorter and not so stout ; 
the tibia of a different form, being nearly straight, except at the 
base whieh is a little bent, and much less dilated within in the 
middle; the posterior femora each with the tooth larger, and 
distinctly visible with a lens of an inch focus. 
I have found this insect on the leaves of the white-thorn 
[Mespilus Oxyacanthd) in hedges on the west side of Turner^s 
Wood, Hampstead, sparingly in April of dark colours, and 
abundantly in September of pale eolours ; and also in many other 
localities in the south of England, but never on any other plant, 
or in company with Ant. Ulmi. 
^ B. Femora minutely dentate. 
4. Anthonomus puhescens ?, Payk., Gyll., Germ., Sehbnh. 
Ovate, testaceous, einereo-pubeseent. Head small, round, tes- 
taeeous, punctulated and pubescent ; eyes globose, brown-black ; 
rostrum rather longer than the head and thorax, slender, a little 
curved, punetulated, deep rufous, shining, and more or less fus- 
cous at the apex. Antennse rather long, slender, rufo-testaeeous, 
clava elongate and fuscous. Thorax transversely impressed and 
constricted anteriorly, a little rounded at the sides, bisinuated at 
the base, moderately convex above, testaeeous, elosely and deeply 
punctured and pubeseent. Seutellum small, elevated and densely 
pubescent. Elytra ovate, very convex above, testaeeous, deeply 
punctate-striate, interstices narrow, eonvex, indistinctly punctu- 
lated and sparingly pubescent. Legs long, testaceous ; anterior 
femora minutely dentate, posterior femora scarcely or very obso- 
letely dentate. Length Inline. 
The form of the rostrum, with the place of insertion of the 
antennse, and the form of the tibise, are very similar to Ant. pe- 
dicularius ; but the absenee of a fascia on the elytra, and the mi- 
nute tooth on each of the femora, at once distinguish this insect 
from the pale varieties of the two preceding, to wLieh it is allied. 
This insect agrees in all its essential eharaeters with Gyllen- 
haPs description of Rhynch. puhescens ; there is however a dif- 
ference in the colour of the head, that of the former being testa- 
ceous, and of the latter black or fuscous ; but colour is so ex- 
tremely variable in these insects that I consider it of very little 
value as a subsidiary specific character.
