158 RHYNCHOPHORA. [Apion. 



insertion of the antennae ; antennae 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 striae, and broad 

 flat interstices, which are wider than the striae; legs rather long and 

 robust. L. 3-3| mm. 



On Vicia sepium and V. cracca ; local, but not uncommon in some districts ; Lon- 

 don district, generally distributed ; Dover ; Hastings ; Devon ; Llaugollen ; Cam- 

 bridge; apparently rare in the 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, ceratum, Steph.). A short broad 

 species, black with the elytra deep blue ; head short and broad with the 

 eyes prominent, rostrum rather long, curved, antennae 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 

 scutelluin deep ; elytra dilated, subglobose, with punctured striae which 

 are about as broad as the interstices ; interstices somewhat raised ; legs 

 moderately long, black. L. 2|-2| mm. 



Male with the rostrum shorter and less curved than in female. 



On Vicia sepium, Lathyrus pratensis, Onobrycliis sativa, TrifoUum recumbens, 

 &c. ; the larva, according to Ferris, 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. aethiops, Herbst. (subsulcatum, Marsh, marchicum, Gyll., nee 

 Herbst., subcoeruleum, 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 tne female the rostrum is more than double 

 as long as the thorax. L. 2|-3 min. 



On Vicia sepium and V. sativa ; less common than the preceding, but apparently 

 generally distributed throughout England and Wales ; Scotland, Sol way, Tweed, 

 Forth, Tay 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 sulcate elytra! strue (on Vicia). 



A. ebeninum, Kirby (Kunzei, Schon.). A rather large and some- 

 what conspicuous species, jet black, sometimes with a slight aeneous 

 reflection, glabrous, shining ; head broad, forehead more or less plainly
