A. ulmi, De G. Brownish-red, or red, clothed with scanty whitish 
pubescence ; head, rostrum and breast pitchy-black or ferruginous ; 
rostrum long, slightly curved, dull, of equal length in both sexes ; 
antennz reddish-testaceous, darker towards apex, inserted further from 
apex than in A. pedicularius ; thorax closely and rather strongly punc- 
tured; scutellum elongate-oval, thickly pubescent; elytra diffusely 
covered with pale hairs, with a slender band in the middle, and a straight 
transverse fascia of whitish pubescence (also on scutellum) behind middle, 
with finely punctured strie and closely sculptured interstices; legs 
reddish or ferruginous, femora more or less dark, anterior pair with a 
very strong tooth, posterior pairs feebly toothed ; basal half of the tibiz 
strongly sinuate on interior margin. LL. 3-4 mm. 
Male with the antenne inserted further in front of middle of rostrum 
than in female. 
On elms, &c.; not uncommon in many localities in the London and southern 
Gistricts and the Midlands; less common further north; Manchester district ; 
Northumberland and Durham district; Scotland rare, Solway, Forth, Moray and 
probably other districts; Ireland, near Dublin and Belfast. 
The colour of this speciesis very variable, and the points of difference 
which have usually been given as separating it from the following are 
sometimes hard to make out satisfactorily ; as a rule the very large 
teeth of the anterior femora afford a decisive character, but in some 
specimens of A. pedicularius the teeth are very much developed, and 
some of the other distinetions are more or less comparative ; the insect, 
however, may at once be known from the latter species by the strongly 
sinuate anterior tibia and the longer and more slender rostrum, which 
has the autenne inserted further from the apex. Bedel appears to class 
A. ulmi and A. pedicularius as synonymous, but I cannot think that he 
is right ii so doing. Mr. Walton says he has found A. u/mi plentifully 
on elms, but never in company with A. pedicularius ; the latter insect 
appears to occur almost entirely on Crategus. 
A. Rosinz, Des Gozis. Oval, rather convex, of the form of A. ulmi 
and with the sculpture of A. Chevrolati; size small; colour varying 
from reddish-brown to ferruginous ; rostrum almost or entirely black ; 
antenne and legs ferruginous, femora usually dark in the middle ;
