162 RHYNCHOPHOKA. 



A. vorax, Herbst. ( $ 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 ; 

 antennae 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, slightly rounded and dilated at sides, with punctured striae, 

 interstices rather narrow ; legs very long. L. 2|-3 mm. 



Male with the antennae inserted a little before the middle of the 

 rostrum which is shorter than in the female and more punctured and 

 pubescent ; antennae with the base more broadly reddish-yellow ; anterior 

 tibiae sinuate and twisted. 



Female with the antenna? inserted just behind middle, more smooth 

 and shining, and with only the two or three basal joints reddish- 

 yellow. 



On Vicia oraccaand other Leguminoscs ; 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. G-yllonhali, Kirby (unicolor, Kirby, pars, cethiops, Gyll., nee 

 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 ; antennae 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- 

 tellum ; scutellum very small ; elytra obovate, moderately long, more 

 or less enlarged behind middle, with well marked shoulders, and with 

 plainly punctured stride, interstices flat, shagreened; legs black, long 

 and slender. L, 2|-3 mm. 



Male with the rostrum shorter than in female and slightly gibbose 

 beneath before the insertion of the antennae.

 London district, rare; Whitstable ; Suffolk; Glunvilles Wootton ; Barmouth ; 

 Yorkshire ; Blackpool ; Northumberland and Durham district very rare (Bold) ; 

 Scotland, very local, Sohvay, 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 

 Killaruey and Avoca on everything, on trees more particularly (Power) j Armagh 

 not common (Johnson). 



A. unicolor, Kirby (platalea, Germ., <$ afrum, Gyll., afcr, auct.).
