vitellina, and Kaltenbach has observed it in a gall on leaves of S. cinerea; M. Bedel 
says that the perfect insect is common “dans les dunes de la Somme ” on S, repens, 
var. argented. 
Group 14. 
Species with at least the elytra strongly meta'lic, blue or greenish- 
blue, glabrous, with the sutural stria of elytra not reaching the base of 
elytra (on Leguminose, chiefly Vicia). 
A. virens, Herbst. (@neocephalum, Gyll.). Black with the elytra 
greenish-blue, head usually more or less eneous, and thorax, as a rule, 
metallic, zneous or greenish, pubescence extremely scanty, almost 
absent, so that the upper surface appears glabrous or almost glabrous; 
head rather large, eyes prominent; rostrum curved, moderately stout, 
slightly dilated at the insertion of the antenne ; thorax cylindrical, 
subconical, finely and sparingly punctured, with a small fovea at base ; 
elytra depressed on disc, considerably widened behind middle, produced 
at apex, with the shoulders well marked, and with strong punctured 
striz, interstices narrow, somewhat raised; legs moderately long. 
i 2=25 mm. 
Male with the rostrum shorter than in female; female with the fore- 
head furrowed between eyes. 
On species of Trifulium ; the larva has been observed in the stems of T. pratense ; 
often taken by sweeping among grass; common and generally distributed throughout 
the greater part of the kingdom. 
A. astragali, Payk. In general form resembling the preceding 
species ; upper surface entirely of a brilliant shining golden bluish-green, 
or greenish colour, sometimes more or less coppery ; head striated be- 
tween eyes ; rostrum moderately long, shining, finely punctured ; thorax 
subcylindrical, about as long as broad at base, coarsely and not closely 
punctured, with a dist:nct central furrow, which in some specimens 
extends for the whole length, and is deepened behind; scutellum 
rather convex; elytra convex but depressed towards base, with 
broad punctured striz and flat, plainly shagreened, interstices ; legs 
moderate, mote or less metallic. L. 2}-2? mm. : 
On the edges of woods on Astragalus, especially Astragalus glyciphyllus (the 
Sweet Astragal or Milkvetch); very rare, although it occurs in moderate numbers 
occasionally where found; Cherry Hinton, near Cambridge (Crotch) ; Guestling, near 
Hastings; neighbourhood of Northampton (Greville) ; Skellingthorpe Wood, Lincoln 
(Rev. H. R. Matthews) ; Barham, Suffolk, and near Leeds (Stephens) ; Scotland, 
extremely rare, Forth district, ‘‘(Queeusferry, Dr. Greville,” Murray’s Cat. 
A. punctigerum, Payk. (sulcz/rons, Kirby). Rather a large species, 
which resembles the two following, but may be easily known by its more 
parallel-sided and much more finely and shallowly punctured thorax ; 
the general colour is black with the elytra dark blue, and the thorax 
sometimes slightly metallic; head striated between eyes which are pro- 
minent ; rostrum rather stout, shining in front, slightly thickened at the
