162 RHYNCHOPHORA. [ Apion. 
A. vorax, Herbst. (3 fuscicorne, Marsh, ¢ pallicorne, Gyll.). This 
species may easily be known by its long form, rather large size, and 
very long legs; colour dull black, with the elytra bluish, pubescence 
grey, rather thick and distinct ; head depressed and striated between 
eyes which are prominent; rostrum not strongly curved, thickened at 
base, with the punctuation rather diffuse in front and dense behind ; 
antenne inserted near middle, long and slender, dark with the base 
testaceous ; thorax about as long as or longer than broad, plainly 
narrowed in front, closely and finely punctured, with a fine central 
furrow which is often obsolete ; scutellum oval, pubescent ; elytra long, 
subparallel, shghtly rounded and dilated at sides, with punctured striz, 
interstices rather narrow ; legs very long. L. 23-3 mm. 
Male with the antenne inserted a little before the middle of the 
rostrum which is shorter than in the female and more punctured and 
pubescent ; antenne with the base more broadly reddish-yellow ; anterior 
tibiz sinuate and twisted. 
Female with the antenne inserted just behind middle, more smooth 
and shining, and with only the two or three basal joints reddish- 
yellow. 
On Vicia cracca and other Leguminose ; also on hazel, ash, &c. ; somewhat local, 
but rather common and widely distributed throughout England and Ireland ; Scot- 
land, Forth district, but it is probably general throughout at least the southern 
counties, 
A. Gyllenhali, Kirby (unicolor, Kirby, pars, ethiops, Gyll., nec 
Herbst.). Black, rather dull, elytra often with a slight iron-blue or 
iron-grey reflection, finely pubescent; head very narrow, coarsely 
punctured, and striate between the eyes which are flat and not prominent; 
rostrum long and rather stout, punctured ; antennew inserted near 
middle, black or pitchy with the base lighter; thorax about as long as 
its breadth at base, coarsely punctured, with a fine stria before scu-

or less enlarged behind middle, with well marked shoulders, and with 
plainly punctured striz, interstices flat, shagreened; legs black, long

London district, rare; Whitstable; Suffolk; Glanvilles Wootton; Barmouth; 
Yorkshire ; Blackpool; Northumberland and Durham district very rare (Bold) ; 
Scotland, very local, Solway, Forth, Clyde and Dee districts; it has been reared by 
Professor Trail from swellings on the stems of Vicia cracca; Aberlady on Geranium 
sanguineum (Power); Ireland, found most abundantly near Waterford and at 
Killarney and Avoca on everything, on trees more particularly (Power) ; Armagh 
not common (Johnson). 
A. unicolor, Kirby (platalea, Germ., ¢ afrum, Gyll., afer, auct.). 
Very closely allied to the preceding, from which it may be easily dis-
