with at least the elytra strongly metallic, Wue or greenish-

 elytra (on Leguminosae, chiefly Vicia). 



A. virens, Herbst. (ceneocephalum, G-yll.). Black with the elytra 

 greenish-blue, head usually more or less aeneous, and thorax, as a rule, 

 metallic, seneous 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 antennae ; 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 

 stria?, interstices narrow, somewhat raised; legs moderately Ion". 

 L. 2-2^ mm. 



Male with the rostrum shorter than in female ; female with the fore- 

 head furrowed between eyes. 



On species of Trifulium ; the larva Las been observed in the stems of T. pratense ,- 

 often taken by sweeping among grass j 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,

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 Hiuton, near Cambridge (Crotch) ; Gnestling, near 

 Hastings; neighbourhood of Northampton (Greville) ; Skellingthorpe Wood, Lincoln

A. punctigrerum, Payk. (sulcifrons, 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 shallowl}- 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-
