Apion. | RHYNCHOPHORA. 149 
larger, with the forehead strongly striated between the eyes and the 
thorax closely, strongly and rugosely punctured; on the rostrum there 
is a distinct central carina prolonged almost to the insertion of the 
antenne, and the thorax is impressed behind on each side at base ; the 
male may be distinguished from the same sex in A. apricans by its 
short, almost subulate, rostrum and longer antenn, and the female may 
be known by its more strongly arched rostrum; all the femora are red 
(the anterior cox and trochanters being also of that colour); the 
anterior tibiz are very dusky testaceous and the other tibiz are black. 
_ 22-3 mm. 
On Ononis spinosa and other species of Ononis ; chiefly on the coast in Britain, 
but it is found throughout the greater part of Europe; locally abundant; Herne 
Bay; Whitstable; Dover; Hastings; Shipley, near Horsham; Isle of Wight ; 
Wallasey, Cheshire; Dr. Sharp has taken it in profusion on the South coast on 
Ononis spinosa and O. arvensis ; the larva lives in the pods of the plants. 
A. trifolii, L. (estivum, Germ., flavipes, Laich, ? F.). This 
species is very closely allied to A. apricans, but may be distinguished by 
having the anterior trochanters pitchy and the four posterior trochanters 
black, whereas in the latter species they are all rufous; the antennz are 
relatively shorter and are entirely black ; the rostrum is very little curved 
in either sex, and the general form is shorter; the average size, moreover, 
is considerably smaller. L. 11-2 mm. 
On the red clover; not so abundant as the preceding, but generally distributed and 
more or less common from the midland couuties southwards; rarer further north. 
Northumberland aud Durham district, rare; Scotland, Solway district, “ Raehills, 
Rey. W. Little, Murray’s Cat.” ; it probably occurs commonly in Ireland. 
A. Ryei, Blackburn. This species may be an extreme form of one 
of the closely allied species, and requires further confirmation ; according 
to the description given in the Entomologist’s Monthly Magazine 
(xi. 128), it may be separated from all the rest in the group with the 
femora and anterior tibiz alone reddish-yellow, by its short, broad, 
sparingly punctured thorax, which is scarcely, if at all, longer than 
broad, and has its sides very evidently rounded ; it is most nearly allied 
to A. apricans (fag), from which it differs in its shorter and more 
strongly bent rostrum, and in its antenne, which have a darker base. 
L. 22 mm. 
Taken sparingly by Mr. C. Lilley and the Rev. T. Blackburn in the Shetland 
Islands, in July, 1874. 
A. dichroum, Bedel (flavipes, Brit. Cat., ? F.). This and the 
succeeding species are easily distinguished from all the others in the 
group by having all the tibie entirely red or reddish-yellow ; from A. 
nigritarse the present species may be known by its larger size, and also 
by having the rostrum black in both sexes, and the anterior coxe yellow- 
red in the male and black in the female ; the forehead is plainly striated 
between the eyes, and the thorax is subcylindrical, very closely and
