158 RHYNCHOPHORA- [ Apion. 
insertion of the antenne ; antennz rather stout, inserted a little before 
middle of rostrum; thorax rather longer than broad, subparallel, with 
the sides a little rounded, slightly constricted in front, finely and not 
closely punctured, more sparingly on disc, central furrow fine usually 
reaching beyond middle ; elytra convex with punctured striz, and broad 
flat interstices, which are wider than the strie; legs rather long and 
robust. L, 3-3; mm. 
On Vicia sepiumand V. cracca ; local, but not uncommon in some districts ; Lon- 
don district, generally distributed ; Dover; Hastings ; Devon; Llangollen ; Cam- 
bridge; apparently rare inthe Midland districts (Repton and Matlock being the only 
localities 1 know of) ; Isle of Man; Northumberland and Durham district ; Scotland, 
very rare, Forth district, ‘“‘ Dalmeny Park, Mr. R. N. Greville,” Murray’s Cat. 
A. pisi, F. (punctifrons, Kirby, wratum, Steph.). A short broad 
species, black with the elytra deep blue; head short and broad with the 
eyes prominent, rostrum rather long, curved, antenne black, often 
obscurely lighter at base ; thorax about as long as the breadth at base, 
strongly punctured, the punctuation being diffuse on disc, furrow before 
scutellum deep; elytra dilated, subglobose, with punctured striae which 
are about as broad as the interstices ; interstices somewhat raised ; legs 
moderately long, black. L. 23-27 mm. 
Male with the rostrum shorter and less curved than in female. 
On Vicia sepium, Lathyrus pratensis, Onobrychis sativa, Trifolium recumbens, 
&c.; the larva, according to Perris, is to be looked for in the pods of Lathyrus 
pratensis ; very common and generally distributed throughout the kingdom ; it is one 
of our most abundant species. 
A. ethiops, Herbst. (subsulcatum, Marsh, marchicum, Gyll., nec 
Herbst., subcwruleum, Steph.). This species may easily be distinguished 
from A. pisi, which it somewhat resembles, by its longer and more 
elegant form, longer rostrum, striate forehead, and much less prominent 
eyes; the elytra are more ovate and more produced behind and less 
short and are of a brighter blue colour ; the interstices also are flatter and 
broader; the coarser sculpture of the thorax and its more conical shape 
will distinguish it from A. punctigerum, which is altogether a stouter 
and more robust insect ; in the female the rostrum is more than double 
as long as the thorax. L. 25-38 mm. 
On Vicia sepium and V. sativa; less common than the preceding, but apparently 
generally distributed throughout England and Wales; Scotland, Solway, ‘Tweed, 
Forth, ‘lay and probably other districts ; Ireland, Waterford and probably general. 
Group 15. 
Species rather large, jet black, without pubescence, with long diffusely 
punctured thorax and very strongly suleate elytral strive (on Vicia). 
A. ebeninum, Kirby (Kwvzei, Schén.). A rather large and some- 
what conspicuous species, jet black, sometimes with a slight geneous 
reflection, glabrous, shining ; head broad, forehead more or less plainly
