(EDEMERID.E. ONCOMERA. 



57 



Green or blue, with a flavescent pile, and very glossy : head and thorax rugu- 

 lose-punctate, the latter transversely coarctate : elytra subulated, coria- 

 ceous, each with a longitudinal elevated line, and a shorter one within 

 towards the scutellum : male with the posterior femora large, curved, con- 

 colorous with the body, the tibite of the same legs robust, bent, compressed, 

 pilose within, and as it were jointed at the base; the anterior tibiae some- 

 times testaceous within at the base ; antennae and palpi blue-green. 



Extremely variable in colour; some examples have the elytra bright violet, 

 and a similar hue on the head ; others are rich grass-green, and some of a 

 yellowish or golden-green. 



The insect described by Linnaeus in Fauna Suecica, No. 716, is evidently not 

 this species, which does not appear to inhabit Sweden, though known to the 

 " great master " as a native of Southern Europe. The Ne. clavipes of 

 Gyllenhal referred to this species, being opaque obscure dull green, with the 

 anterior legs and base of the antennae pale testaceous ; the mouth and palpi 

 ferruginous, &c. 



Very abundant during the summer throughout the south of 

 England. "Bristol.'"' — G. Waring, Esq. "On the blossoms of 

 Geranium sanguineum, Wood Ditton."" — Rev. L. Jenyns. " Wes-

 Ne. marginata. Fabricius. — N. G. marginata. Steph. Catal. 250. No. 2492. 



Head and thorax black, immaculate : elytra testaceous, with the entire margin

An indigenous specimen, I believe, of this species is in the 

 collection of Mr. Haworth, who obtained it from that of Mr. 

 Francillon.
